Frequently Asked Questions

 

When do I know it's time to replace my system?


When the system starts giving you more problems than seem cost-effective to fix, particularly when major components such as the compressor start making unusual noises or otherwise indicating need for a service call. When faced with major repairs, we can help you make the right choice. Replacing a compressor is somewhat less expensive than replacing the entire unit, but new units may give you greater efficiency and lower operating costs in the long run.

 

My present heating and cooling system does not keep us comfortable. Should I have a larger system installed?
In most cases no. Usually the problem is due to poor system design or installation. More likely you will need duct work modifications, a manual heat load calculation, or possibly an energy audit to find the problem areas and correct them.

What is the average life of a central air conditioning system?
It can vary, depending on how much the system is used and how regularly it is checked or serviced. Generally, the average life of cooling units built in the 1970s and 1980s is about 15 years, but individual units may vary and last much longer, depending on use and how well they are maintained. Heat pumps have about the same life span -- an ARI survey showed average heat pump life to be about 14 years when recommended maintenance procedures were followed. Newer units are expected to last even longer.

Can homeowners repair their own air conditioners?
In most cases, definitely not. Cooling systems today are more complicated to service and usually require expert attention in order to comply with federal regulations, such as the Clean Air Act which prohibits releasing refrigerants into the atmosphere. An EPA - certified air conditioning contractor or service technician should be called at the first sign of trouble.

What is the best type of system to meet all indoor comfort needs?
The best system depends on many variables, including family size, house location and design, and utility cost and availability. The optimum indoor comfort system might include high efficiency central air conditioning and heating, a high-efficiency air cleaner, and a central humidifier.

How often should I change the air filter in my system?
Check it at least every month during peak use, and replace it when it looks dirty enough to significantly impair the air flow through it. Some filters, such as media filters or electronic air cleaners are washable, others are disposable and must be replaced.
