Heating & Air Conditioning Faqs
     Willis Carrier discovered the principles of air conditioning in 1902. Since that time, the company that bears his name has been the leader in indoor comfort. Today, Carrier Corporation holds more than 800 U.S. patents, and its engineers continue to build on the legacy of innovation.
     Providing indoor weather solutions means more than supplying heating or cooling when you need it. Carrier offers a total system of high-efficiency products designed to give you customized control of your indoor weather to precisely fit
the needs of your lifestyle.
Mr. Willis Carrier

What is a SEER?
Seasonal Energy Efficiency Ratio.
This is like a MPG rating on a car. The higher the number the more energy efficient. New units have ratings from 10 to 17 SEER, older units had ratings as low as 6 SEER.

What is an AFUE?
Annual Fuel Utilization Efficiency.
The higher the number the more efficient it is. New units have ratings from 78% to 96%. Older units have ratings of 55 - 60%.

What is HSPF?
Heating Seasonal Performance Factor
The higher the number, the more efficient. New units have ratings from 7.0 to 9.4.

Which is best, Heat Pump or Natural Gas Heat?
That depends on many things. The price of Natural Gas & Electricity, how well your house is insulated, how your duct is installed and insulated.

When I buy a new Air Conditioning Unit, do I need a new indoor coil?
In most cases yes. If you don't, the life of your Air Conditioner may be shortened, not work properly and it could use more electricity than necessary.

What is the best way to clean duct?
Power vacuum with HEPA filtration along with a reversible power brush. The HEPA filter cleans the air and the brush scrubs the duct clean.

Is there an Air Conditioner available that uses a new, safe type of Freon?
Yes. At this time Carrier has had a unit available since 1996.

Do you have maintenance plans?
We have 4 residential maintenance plans. We can customize a plan for any commercial or industrial need.
