Heating and Air Conditioning questions, answered by experts

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

Yes, through thorough cleaning and inspection, optimizing functionality, and reducing energy use.

The higher the BTU rating an air conditioner has, the more effective it can be at cooling your space. It will cool off your room faster in the short term. However, over the long term, if the unit has too many BTUs for the space, it can wear down the unit faster and shorten its life span.

Yes. Your air supply should be balanced. The return and supply ducts need to maintain that balance, and this only occurs because an equal amount of air should be entering and leaving your HVAC system. Changes in pressure, extreme weather, and blocking vents with furniture or your stuff can make the air supply unbalanced and cause your home to get too cold or hot.

During the summer, it’s best to set your AC to 78 degrees when you’re home and awake, according to the Department of Energy (DOE). For better energy efficiency, raise the temperature slightly to 85 degrees while you’re out of the house. The National Sleep Foundation advises lowering your thermostat to between 60 and 67 degrees when you’re asleep.
