Frequently Asked Questions

Why is A-TEMP available seven-days a week, from 7 a.m. to 7 p.m.?


We believe homeowners deserve flexible options that fit their schedules. When the heat stops working in the dead of winter, or your home won’t cool down during the dog days, the last thing you need is the added inconvenience of having to take time off from work or rearrange your schedule to let us in your house.

Sometimes scheduling issues can’t be avoided. However, by being available seven-days a week, we provide you with more flexibility than other HVAC contractors in the area. And we never charge overtime. So if a job keeps us at your house past 7 p.m., our rates won’t change.

How often should I change my filter?


On standard filtration systems it is recommended to inspect and or change your filters ever 1-3 months. Some higher end filtration systems may only need to be changed every 6-12 months. Regardless what filtration system your home has it is important to inspect it frequently.

Is annual maintenance recommended?


All manufactures highly recommend an annual safety inspection and tune-up of your heating and cooling equipment.

Why should I clean my ducts?


The American Lung Association in their consumer awareness bulletin #1001 says microbes and fungi find nourishment in improperly maintained air ducts, air conditioners, heat pumps, evaporator coils and furnaces. Cleaning your system removes these harmful agents.

How can I reduce my heating costs?


By installing a state of the art home comfort system you could reduce your heating cost by as much as 50%. Is your home comfort system old?

How does an air conditioner work?


An air conditioner cleans, circulates, cools and dehumidifies (removes undesirable moisture from) indoor air. A filter cleans the air by trapping dust and other small particles. An air handler (blower built into the system) circulates it, while the cooling and dehumidifying are accomplished by a process called refrigeration.

How does gas heat work?


If it is a gas furnace, the heat is supplied by the burning of natural gas. A mixture of gas and air flows into the heat exchanger and is ignited by the pilot light or hot surface ignitor. Combustion occurs, and warm air from the burner flame rises to fill a chamber known as a heat exchanger. The heat exchanger becomes hot. Air passing around the heat exchanger absorbs that warmth, continues into the air ducts and the heat is distributed through your home. The by-products of combustion pass upward through a venting system and escape through the flue.

How does an electric heat work?


If the furnace is electric, heat is generated by an electric heating element. Electric current traveling through the element creates heat. By the heat transfer processes called conduction and convection, heat is transferred into the air stream and flows through the air ducts into the rooms of your home.

What is a thermostat? Do I need one in every room?


Whether you heat your home with gas or electricity, a wall thermostat will be installed. This measures room temperature and turns the central heating system off or on as the temperature rises or falls to designated levels. Careful location of the thermostat is an essential consideration in maintaining maximum comfort levels in your home. Typically, only one thermostat is required. However, homes that have multiple furnaces or zoning systems, will require more.

How can I heat or cool my house efficiently?


Set thermostat at one temperature. Constant adjusting can cause higher utility costs. If using your thermostat as a setback type, limit the setbacks to twice a day such as when you are at work and when you are sleeping. Only setback the thermostat 6% of desired temperature (approximately five degrees). In heating, try not to set the thermostat below 65 degrees. In cooling, try not to set the thermostat below 70 degrees. Besides higher utility costs, this can cause the indoor coil to freeze and cause condensation in the house.
