Frequently Asked Questions

Heating and Air Conditioner FAQ’s

How much will my new air conditioning system cost?

The answer is “That depends.” There are many factors which must be considered: the efficiency of the equipment, the size of your home, is the duct work installed and in good condition, do you need a thermostat or electronic air cleaner. In most cases, replacing your whole system, indoor and outdoor components, will result in a more efficient, longer lasting system but will also cost a little more.

How often should I change or clean my filters?

Filters should generally be replaced every month when the system is running. Replace filters with the same kind and size as original filter. If your filter is not disposable, follow the manufacturer instructions for cleaning.

Should I cover my outdoor unit in the winter?

Covering the unit is not necessary. Air conditioners are manufactured to withstand all possible climate changes. In fact, rain helps keep your unit clean. Of course, because heat pumps run all year long, they should never be covered.

Is there any advantage to setting my thermostat fan to “ON” so the fan runs constantly?

There are a couple. One is that you get constant filtering of the air in your home. The other is that because the air is moving, you have a more even temperature throughout. I’ve heard a lot about new refrigerants. Do I need to think about them when buying a system?

How close to the outdoor unit should I plant shrubs or flowers?

Manufacturers generally agree that plants should not be closer than 18 inches. Air conditioners need to take in and exhaust air to operate efficiently. If air cannot circulate, the unit could build up heat and require service.

I need a new outdoor unit, but my indoor unit works fine. What are the advantages of replacing my whole system at the same time?

Air conditioners are designed as matched systems, with an efficiency rating given for the whole system. If you replace only one part, you do not get the advantage of many technology changes that make the system work efficiently to ensure comfort. Also, the indoor system contains a cooling coil which may be partially blocked by particles that will decrease efficiency. Further, if your whole system is replaced, you will be less likely to need service in the near future.

What size system do I need for my home?

There are many things which will determine the size (capacity) system your home requires. Some of these are: square feet to be cooled, climate, humidity, number of windows, insulation factors, which direction your home faces, heat producing appliances, and even the number of people who will be in the home.
