Frequently Asked Questions


What does HVAC stand for?

HVAC (pronounced h-vac or spelled out) stands for Heating, Ventilation and Air Conditioning. 


What is meant by a ton of cooling?

Confusingly, the unit has nothing to do with weight, as used in everyday language. One ton of refrigeration is the term used to refer to 12,000 B.T.U.s/hour (British Thermal Units/Hour) of cooling effect. Thus, a condensing unit with a cooling capacity of 60,000 B.T.U.s/hour is said to have a capacity of 5 tons.


Where is my filter located?

Usually there is a removable filter in the return air duct near the furnace. Sometimes the filter is located in the furnace itself next to the blower motor.


How to keep my second floor from getting too hot?

It is common to find the upstairs 10 degrees hotter in the summer than the 1st floor. One of the best way to help even out the temperature is to turn your blower to the “on” position and run it all the time. Even if the thermostat isn’t calling for cooling the cooler 1st floor temp will be pushed upstairs. 


How often should I replace my air filter?

There’s no one-size-fits-all answer. The frequency of filter changes is driven by how much your heating and air conditioning system operates, which is also driven by your individual climate. Start by checking the system’s filters at least once a month. Hold the used filter up to the light and compare it to a clean “spare.” When light is obscured by captured dust and dirt particles, the old filter should be changed. At a minimum, it is always a good idea to change filters at the start of the heating and cooling seasons and then in between according to your need. 


How long does a furnace or air conditioner last?

This is a hard question to answer. Some brands last longer than others. Units that are maintained regularly tend to last longer. In general a furnace and air conditioner last 15 to 20 years.


How often should I have my equipment serviced?

Regaudless of the kind of HVAC equipment you have, it should be inspected and serviced at least once a year. We recommend having your heating system checked in the Fall and your air conditioning inspected in the Spring. Annual check-ups will increase the dependability, prolong the lifespan of your equipment and help maintain a safe and healthy operation.
