Consumer FAQ

Is a larger HVAC unit better?

A bigger system isn’t always better; a contractor should size the heating and cooling system based on the size of your house, level of insulation, and windows.

Is there a “rule of thumb” or a number of tons required per square feet in the size of my house?

The correct information that a quality HVAC contractor will need to collect to help determine the proper size of the equipment needed for your house would relate to the number of windows in the house, the direction in which they face, the state of insulation of the house etc.

These would enable him to accurately calculate the load, to determine suitable heating/cooling equipment needed for installation.

Beware of any contractor who uses the “rule of the thumb” method for calculations or relies on the specifications of the earlier installed equipment for submitting an estimate.

Should I select the contractor with the lowest price?

A quality contractor will not offer price as the only consideration. While it is a major factor, there often are valid reasons for price differences. Consider the efficiency and warranty as a part of the price consideration.

What does HVACR mean?

HVACR stands for heating, ventilating and air conditioning/ refrigeration (HVACR). Sometimes you see it listed as HVAC heating, ventilating and air conditioning.

When comparing contractors' proposals (bids), what do I need to consider?

Be sure to compare cost, energy efficiency and warranties. A lowest price may not be the best deal if it’s not the most efficient because your energy costs will be higher.
