Two Stage Air Conditioning System Advantages
What is the advantage of a two stage air conditioning system compared to a a single stage air conditioning system?
Benefits of a Two Stage Air Conditioning System Verses a Single Stage AC Unit:
A two stage air conditioning system has many more comfort features, one of the best features is the on-demand dehumidification feature. The on-demand dehumidification feature will allow you to feel more comfortable at a higher temperature set point with a lower percentage of humidity in the air. Comfort aside, when moisture levels are high, there’s a higher potential for mold and other pollutant problems that could potentially lead to health issues.
How does it work?
The air handler fans speed ramps down into a lower speed utilizing a variable speed motor, when it ramps down to a lower speed it starts pulling more humidity out of the home.
Here is an Example
When you set your thermostat to 76° on the single stage system the air-conditioner will continue to run at 100% capacity in order to bring it down to 76°. However, on a 2 stage system with the humidity control feature you can set your thermostat to 78° and then set the humidity at 45%. Once the air-conditioner reaches 78° The two stage air conditioning unit will drop down into first stage and the fan speed will drop down as well, this allows the air conditioning unit to begin the dehumidification process and then starts to pull the humidity level down until it reaches 45% humidity in the home. Once it reaches 45% humidity the AC unit will shut down and it will feel like 76° even though the temperature is actually 78° in the home. This is because the humidity is only at 45%. This will save you money on your electric bill because your air conditioner does not have to operate at 100% capacity all the time of time in order to bring your home temperature down 76°
A two stage air conditioning system works 2 stages on the compressor mode, it starts up at 66% drawing less amperage upon start up and this is where you consume most of your energy costs. If the heat load in the home calls for more cooling 15 seconds later the 2nd stage kicks in the 100% capacity mode. Example, if you have a 4 ton air-conditioner with a 2 stage system it will start up as if it were a 2.5 ton drawing the amperage of a 2.5 ton system and then 15 seconds later it will go to 100% (only if the heat load in the home calls for 100% capacity) which will be a full 4 ton capacity however on a single stage system it will always start up at 100% capacity and draw the amperage that a 4 ton compressor will need and that 100% capacity is what winds up costing you more money on your energy bill. Dual stage air conditioners also tend to last longer because they are not running at full capacity all the time.
Two stage cooling means the air conditioner or heat pump has a compressor with two levels of operation: high for hot summer days and low for milder days. Since the low setting is adequate to meet household-cooling demands 80% of the time, a two-stage unit runs for longer periods and produces more even temperatures.
Longer cooling cycles also translate to quieter, more efficient operation, enhanced humidity control, substantial savings on your annual energy costs and extended lifespan of your cooling and heating system. Compared to a single-stage unit, a dual stage air conditioner or heat pump can remove twice as much moisture from the air. This is important because when moisture levels are high, there’s a higher potential for mold and other pollutant problems.
Purchasing a new air conditioning system is one of the most costly home improvement investments you will make so when it’s time to replace you air conditioning system or heat pump, call a name you can trust.

Keep cool, save money
Mike Thompson, of Universal Air and Heat, answers some questions that will help readers ensure their heating and cooling systems are running as efficiently as possible – and what to do if they’re not
Living in South Florida, it is nearly impossible to overstate the importance of a properly functioning air conditioning system. Not only is it necessary to keep you cool during nearly year round hot temperatures, but it will keep your monthly electric bill under control.

Living in South Florida, it is impossible to overstate the importance of a properly functioning air-conditioning system. Not only is it necessary to keep you cool during nearly year round hot temperatures, but it will also help keep your monthly electric bill under control.
Question: What are SEERS?
Answer: SEER stands for “seasonal energy efficiency ratio.” The SEER rating is the BTU of cooling output during its normal annual usage divided by the total electric energy input in watt hours during the same time frame. SEERS range from 13 (lowest) and 21 (highest). The higher the SEER rating, the more energy efficient the system is.
Question: I bought my first house and am now responsible for air-conditioning care. What is the difference between all these stage systems and compressors, and what will help me with my electric bills?
Answer: A two-stage system is a much higher-quality system than a single-stage system. Most people purchase single-stage air-conditioning units because they are less expensive than a two- stage, but aside from the price factor, most people are not properly educated on the benefits of having a two-stage system. A single stage starts up at 100% capacity while two stages start up at 60% capacity, and 15 seconds later go into 100% capacity. A two-stage system draws less amperage on start up, which helps you save money on the electrical bill. Other added benefits of the two-stage system include on demand de-humidification features. If your home reaches the desired temperature set point but the humidity level is very high in the home, the system will go into de-humidification mode that brings the humidity levels down to the requested level. This allows you to have your home set at a higher temperature set point with less humidity in the air, so you are more comfortable in your home at an even higher temperature set point because there is less humidity in the air.
Question: It’s 98 degrees outside and my AC is not blowing. What do I do?
Answer: Check the breakers, and if it is not related to an electrical short, call for service. You can check to see if you have a dirty filter, as this may cause the unit to freeze up.
Question: How do I care for the filter?
Answer: Filters should be changed or cleaned once per month. You can clean them by vacuuming it off and washing it with water (if it’s a washable filter). Let it dry completely before placing it back in. Use a good quality filter like an electrostatic washable, which we sell and can have custom made to fit in the AC unit. If you prefer to change the filter every month, invest in a sponge pad smart filter that has a custom-made aluminum frame and a rubber seal gasket that goes along with the top of the filter. With filters removed, check the coils by shining a flashlight. If they appear to have microbial growth on the coils or appear to be clogged in any way by dog hair or dirt impacts, have a specialist come in for a coil acid cleaning. The fan blower inside the AC should also be removed and cleaned once every two to three years.
Question: How often should I clean my air ducts?
Answer: If you have a really good filter and a UV light, you should only have to clean your ducts every three to four years. If you have a standard filter and no UV light, you should probably clean your ducts every one to two years. Different air-duct cleaning packages are available, depending on how dirty the ducts are. Call our experts and we can help determine how severe the air-duct buildup is.
Question: How do I care for my AC’s drain line?
Answer: Pour a little bit of bleach down the drain line pipe every six months — that will reduce the amount of algae build up in the drain line and reduce the chance of the drain line filling up with water.
Question: How often should I have my AC tuned up?
Answer: It is recommended that you check your unit every six months. We perform a 21-point inspection, and make recommendations on anything that needs to be done. Our service professionals arrive with fully- stocked trucks with all the common parts and standard tools needed for complete coil cleaning, fan cleanings, drainline cleanings, UV light installations, etc.

22 Energy Saving Tips To Save You Money
Little changes that can add up to big savings on your annual cooling costs
With energy prices on the rise, these energy saving tips can amount to big savings on your cooling and heating expense. Energy costs in South Florida are 40% higher than the national average, according to EIA’s Residential Energy Consumption Survey. Your air conditioning system is responsible for up to 60% of your energy consumption in South Florida. With just a few simple changes to your lifestyle and your home, you could be saving hundreds of dollars on your annual energy bills.
- Use ceiling fans to cool off for less. Ceiling fans use no more electricity than a standard light bulb. However, be sure to turn fans off when you leave the room- a fan that runs all the time costs up to $7 a month.
- Switch your ceiling fan to turn in a counter-clockwise direction In the summer; in the winter, run it at low speed, but clockwise.
- Cool your home at 78 degrees or higher with the thermostat fan switched to auto. For additional savings, raise your thermostat to 82 degrees or higher when you’re away.
- Install a programmable thermostat to adjust your temperature during the day.
- Close your exterior doors and windows tightly when the AC is on. Save even more by turning off kitchen and bath exhaust fans.
- Window tinting can help reduce room temperature in rooms that have a sunny exposure. Especially a south west exposure in late afternoon when the outside temperature is at its highest.
- Clean or replace the A/C filter at least once per month to help your unit run more efficiently and trim cooling costs.
- Consider purchasing an lifetime electrostatic air filter. It will do a better job of keeping your coil clean and trap allergens better than the thick hypoallergenic disposable air filters that restrict air flow.
- If you have an older air conditioner with a SEER rating of under 16, consider upgrading to a higher efficiency model. Not only will your AC be more efficient, you could also be eligible for a utility company rebate and Energy Star Federal Tax Credit of up to $300. The higher the SEER rating, the more your will save. Consider a two stage or multi-stage AC unit for even more saving.
- If you have a manual thermostat be sure the fan switch is set to “auto” to save energy. Leaving it in the “on” position keeps air running constantly.
- Block the sun from overheating your home! Inside, use shades, blinds and drapes. Outside, use awnings, trees and shrubs..
- Get a AC tune-up. Running an inefficient AC system can result in high monthly bills.
- Open interior doors so that cooled air flows freely throughout your home.
- Repair leaky ducts to reduce heating and cooling costs.
- Install attic insulation to reduce high home cooling costs up to 20%. You’ll save money each month and may qualify for a rebate.
- Check for household leaks to make sure air isn’t escaping through openings such as fireplace dampers, doors and windows. Make sure your weatherstripping is not allowing air to escape. If it is, replace it.
- Decorate for a cooler home by hanging light-colored curtains that allow light to enter a room while blocking some of the sun’s rays, and light-colored paint to reflect heat.
- Close unused air vents. If you have central AC you can close air vent and doors in rooms you’re not using so you’re not paying to cool them.
- Plant trees to provide shade on the sunny side of your home. Use large potted plants that can provide adequate shade (Ficus Trees) if you have a patio apartment.
- Install more ceiling fans. Because the breeze of a fan can make you feel three to four degrees cooler, you can raise that thermostat and still stay comfortable.
- When you have your roof replaced, go with a lighter color. The more reflective the color the lower your attic temperature. One study showed a 20 degree temperature difference in the attic when the homeowner changed from dark grey roof tiles to white.
- Have your AC system evaporator coils cleaned, if needed. Restricted air flow will not only cause your air conditioning unit to freeze up, it will impact your cooling costs. An air conditioner with restricted air flow causes your air conditioner to work much harder and can potentially damage your air conditioner and reduce its lifespan.

Comparing R22 with 410a Refrigerant
My Air Conditioner Uses R22 Refrigerant, Can I Top It Off With R410a?
The two refrigerants are completely incompatible. It would be the equivalent of topping a car off with synthetic oil when it uses regular motor oil. The two can not be mixed without causing severe damage to your air conditioner or heat pump.
All air conditioners use an oil to keep the compressor lubricated during operation. R22 air conditioners use mineral oil and R410A systems use synthetic oil. The synthetic oil is generally more soluble with R410A than mineral oil is with R22. This means the R-410A system operates more efficiently reducing wear and tear on the compressor.
In the past, having a Freon leak in your air conditioner wouldn’t be that expensive, but that was before the prices of R22 Freon went through the roof. At around $75.00-$100.00 a pound of R22 and the average fill up being around 2-5 lbs, topping-off an air conditioner with a Freon leak is now a very expensive option.
Freon leaks only become worse over time and the cause of the leak needs to be addressed before it damages your air conditioner or heat pump. Refrigerant doesn’t dissipate or break down over time and heavy use. Air conditioners and heat pumps, like refrigerators, use a sealed system. If you are low on refrigerant, it is because you have a leak in your air conditioning or heat pump system.
Why is R22 Refrigerant So Expensive?
R22 is a common refrigerant that is currently being phased out in the U.S. due to its very high potential to exacerbate ozone-depletion. R22 is known as a global warming gas. U.S. EPA has tried to reduce use of this material by imposing strict quotas on its production.
R22 Vs R410a Refrigerant; What You Need To Know:
As of 2010 is no longer allowed to be used in newly-manufactured air conditioners
Contributes to the depletion of the ozone layer
Is less capable of absorbing and releasing heat than R410a refrigerant, making it the less efficient refrigerant
Is becoming more and more expensive as its use is phased out
Is approved for use in all newly-manufactured air conditioners
Does not contribute to the depletion of the ozone layer
Is better at absorbing and releasing heat than R22 refrigerant, making it more efficient to use
Requires the use of tougher and more durable air conditioner parts, which reduces the risk of your system overheating and breaking down
Is It Normal For Air Conditioners to Lose Freon Over Time?
Does Refrigerant Dissipate or Beak Down?
The short answer is, no. Air conditioners and heat pumps do not lose refrigerant due to hard use after a hot summer season or over the course of time. The Freon, or refrigerant, is only the medium used to transfer heat from the inside of the home to the outside. Like refrigerators, air conditioners and heat pumps have a sealed refrigerant system. Freon does not dissipate or breakdown.
So where did it go? If you are low on Freon, it is because you have a leak somewhere in your air conditioning system or heat pump.
Freon leaks are typically found at the schrader valve, valve cores, evaporator coil, copper lines, “U” connectors, weld joints, electrical connection to the compressor body, or the copper tubing. Most of the time, the leak will usually occur in the evaporator coil.
The coil is made up of straight tubes, fins, “U” connectors and various other refrigerant carrying pieces that are welded together at the factory and should remain leak proof for the life of the AC unit. However, that’s not always the case.
Why is My Air Conditioner Leaking Freon?
The welds and parts are made up of different metals that expand and contract differently when exposed to extreme temperature fluctuations. These welds sometimes start to fail or crack resulting in a refrigerant leak.
There is also some long term deterioration that comes along with copper coils. Formic Acid, a byproduct of building materials, is released and is corrosive to copper. Over time it can etch away at the copper tubes and create microscopic leaks in the tubes themselves.
Newer homes are often notorious for developing Freon leaks quicker than older and more established homes because of the presence of more chemicals, such as Formaldehyde, in the building products.
Where Are Freon Leaks Typically Found?
Freon leaks are often found in the evaporator coil. The weakest areas are generally where the metal is stressed the most, the “U” joint, weld points and areas that are subject to the most vibration.
Other places include the schrader valve. The same type of valve you would find on your tire to fill it with air. Sometimes the rubber seals deteriorate or the schrader valve gets stuck and allows Freon or refrigerant to leak out of the air conditioning system.
If you have a heat pump, heat pumps have accumulators. Accumulators are necessary for the heat pump to provide heat in the winter are usually made from steel and after a few years they can begin to rust.
A capillary tube leak on the inside evaporator coil, or if you have a heat pump, on the outside heat pump condensing unit.
Filter dryers are installed in all refrigeration systems and are necessary for absorbing minute amounts of moisture in the system. They also filter out contaminants before they get into key components which would otherwise be damaged or plugged. These filter dryers have screens and desiccant inside them and the outer shell is made if steel. Over Time, Steel can rust.
The line set which carries refrigerant back forth from the condenser to the evaporator coil has been pierced or damaged. Damage can occur from a lawn mower or someone piercing the line set.
How Do You Find a Freon Leak?
There are several ways to test the lines in order to determine where the leak is.
The most precise method for locating Freon leaks is for the technician to install a liquid tracer into the air conditioning or heat pump system, and allow it to circulate about two weeks. A small amount of fluorescent dye is added to an air conditioning system or heat pump and allowed to circulate. The dye escapes with the system’s refrigerant or fluid and remains at all leak sites. When the system is scanned with an ultraviolet inspection lamp, the dye fluoresces brilliantly to pinpoint the exact source of every leak. Proven to find multiple and intermittent leaks undetectable by any other method. Even leaks smaller than 1/8 ounce per year.
If your air conditioner or heat pump is is losing Freon, it will require a professional air conditioning technician to accurately determine where the leak is occurring and recommend the most effective solution to repair the problem.
The following issues may indicate a refrigerant leak:
- Your home takes a long time to cool
- Warm air is coming out of your air registers
- Your evaporator coils are frozen over
- You hear a hissing sound
R22 Freon Is Expensive; Can I top It Off With R410a?
Unfortunately, R22 is incompatible with R40a. R22 Freon is mineral oil based and R410a refrigerant is synthetic based. Mixing them together will cause a great deal of damage to your air conditioner or heat pump. It would be like using synthetic oil to top off a car that uses regular oil.
R22 refrigerant costs around $100 per lb and the average fill up is 2-5 lbs, topping-off an R22 air conditioner can be very expensive.
The reason why R22 has become so expensive is because it is being phased out in the U.S. due to its very high potential to exacerbate ozone depletion. U.S. EPA has tried to reduce use of this material by imposing strict quotas on its production.

Energy Efficiency Ratings
Energy-efficient heating and cooling products make home comfort more affordable. Understanding efficiency ratings is an important first step in choosing the system that’s right for you. Let’s decipher the standards used to measure the efficiency of furnaces, air conditioners and heat pumps, and how they impact your monthly utility bill:
Furnaces: If you have an older furnace, you could save considerably on your heating bill by upgrading to a higher-efficiency model – start by checking out the AFUE rating.
AFUE (Annual Fuel Utilization Efficiency)
Standard measurement of efficiency for gas and oil-fired furnaces
Tells you how much of your fuel is used to heat your home and how much is wasted
The higher the rating, the greater the efficiency
Minimum required rating is 78%
Many manufacturers offer a full line of furnaces with AFUE ratings of up to 98.3%
Air Conditioners and Heat Pumps: Upgrading to high-efficiency heat pumps and air conditioners requires an initial investment, but you’ll quickly see payback in the form of lower, annual utility bills for the life of your system. To compare the efficiency of these products, look for two numbers –SEER rating for cooling, and if you’re considering a heat pump, HSPF for heating.
SEER (Seasonal Energy Efficiency Ratio)
Standard measurement of efficiency for the cooling process of air conditioners and heat pumps
The higher the number, the greater the efficiency
Minimum required SEER rating is 13
Many manufacturers of residential cooling systems have units with SEER ratings of up to 20.5
HSPF (Heating Seasonal Performance Factor)
Standard measurement of the efficiency of the heating mode of heat pumps
The higher the number, the greater the efficiency
Minimum required HSPF rating is 7.7
Many manufacturers of residential heating and cooling systems make heat pumps with HSPF ratings from up to
Cost Savings: Upgrading to high-efficiency heat pumps and air conditioners requires an initial investment, but you’ll quickly see payback in the form of lower, annual utility bills for the life of your system.
Matching Your System for Optimum Efficiency
An additional factor that affects the efficiency of your system is your indoor coil (also called an evaporator coil). In order to maximize SEER and HSPF ratings and ensure proper performance, your air conditioner or heat pump unit must be matched with the correct indoor coil. When you replace an existing system, make sure you consider replacing the indoor coil so you get the most efficient performance.
Universal air and Heat only sells and installs matched heating and cooling system components in accordance with manufacturer specifications.

Energy Savings Tips – Air Duct Cleaning Saves At Least 11 Percent On Your Annual Energy Costs
Heating, ventilation and air conditioning a home or small commercial building is requires a lot of energy.
Your HVAC (heating, air conditioning and Ventilation) system accounts for 30 percent of the energy used in an average home or small building. In addition, heating and cooling larger dwellings accounts for up to half of the energy use. On the whole, heating, ventilation and air conditioning systems are by far the largest sources of energy use within a home or building. Heating and air conditioning systems tend to be the most important and expensive investment we make to our property but somehow, we take it for granted and most heating and cooling systems tend to be poorly maintained. These systems, which are used every day of the year, get dirty and can become heavily contaminated with dirt, dust, animal dander, and more.
Your HVAC (heating, air conditioning and Ventilation) system accounts for 30 percent of the energy used in an average home or small building.
Believe it or not, heating and cooling systems in new homes and buildings are often heavily fouled before occupants move in due to construction debris. Contaminated heating and cooling systems contribute to poor indoor air quality in the form of increased airborne particulates and reduced comfort. Fouled systems have to work much harder due to decreased air flow which makes them more prone to failure. When it comes to having a productive, energy-efficient heating and air conditioning system, air flow is king. Increased air flow equals better performance. When HVAC systems become fouled, air flow is reduced. Dirty filters, clogged coils, fouled blowers and other components impede air flow and and make your air conditioning unit work harder and result in increased energy costs.
The solution is to have the heating and air conditioning system professionally cleaned by a NADCA certified Air systems Cleaning Specialist. Professional cleaning for a heating and air conditioning system entails cleaning not only the ductwork, but also the vents, registers, blower, coils, and other complete cleaning of the heating and air conditioning system is a highly specialized duct cleaning service that differs from the routine maintenance provided by the air conditioning technician sent out to clean and adjust the air conditioners. Complete cleaning of the heating and air conditioning system is important to ensure your air conditioning system continues to operate at peak efficiency. Call Universal Air and Heat to thoroughly clean your air handler components. 866-999-2665
So how much does it cost to operate a fouled heating and cooling system?
That is the question asked by the National Air Duct Cleaners Association (NADCA), a not-for-profit association representing companies around the world that inspect, clean and restore heating and air conditioning systems. In 2008 NADCA initiated a project with researchers from the University of Colorado at Boulder (CU) to conduct an in-depth study of this issue. Researchers conducted two field trials to assess the accuracy of the computer model.
Through this process, researchers came to realize that there was no comprehensive data available to quantify the savings that can be achieved through cleaning of heavily-fouled systems, typical of systems regularly encountered by NADCA members. (For purposes of this research, “Heavily-fouled” systems are defined as systems where complete cleaning results in a pressure change of at least 30 percent. Pressure change is simply an easier way to measure air flow.)
The calculations in the computer model were based on data collected from lightly-fouled systems – systems that are not very dirty.
According to the results of the study, cleaning even lightly-fouled systems can produce substantial energy savings. These findings are based on complete cleaning of heating and air conditioning systems in accordance with NADCA’s ACR 2006 Standard, which includes cleaning ductwork, coils, blower, other air-side system components, and changing the filter. Based on the initial research, cleaning a lightly-fouled system provides, on average, an 11 percent savings off of the energy used for heating and air conditioning systems.
Researchers have proven that cleaning even lightly-fouled heating and cooling systems can result in energy savings of 11 percent. Cleaning heavily-fouled systems is expected to produce an even greater savings than cleaning systems that are essentially clean. In addition to these savings, consumers who have their heating and cooling system cleaned can benefit from improved indoor air quality, reduced maintenance costs and extended life expectancy for the heating and cooling system. While not yet confirmed, cleaning
heavily-fouled systems is expected to produce even greater energy savings.
