What we do

Our services

Heat Pump, Furnace, & Air Conditioning Sales, Installation, and Maintenance​

Call us out to your home so we can discuss what model of heating system will work best in your home. After conducting a heat gain and loss evaluation of your home, we will show you the benefits of each system and how they differ from each other. Once you decide on the system you want, you’ll receive and estimate right on the spot.

After determining which system is best for your home, we are able to install your system in 6 to 7 hours. For most homes, we recommend Amana systems because of their reliability and lifetime replacement warranty.

Proper maintenance is the best way to extend the life of your system. Our spring maintenance check involves examining your entire system to ensure that it will function properly when the summer heat arrives. We’ll check freon levels, electrical components, filter, and fan motors.

Keep Your House Warm

You may not pay much attention to your furnace — other than to turn it on in the winter and off in the summer — but the truth is, a lot goes into making sure this machine keeps working. From the ignition to the filter, from the burner to the blower, your furnace is made up of many different parts, each of which must be in good condition in order for the furnace to work effectively.

If any one of these individual components breaks down, it could significantly impact the operation of your furnace.

At Gregory Heating and Air, we can quickly diagnose and repair your furnace so that you don’t have to deal with a cold home any longer than is necessary. If your furnace smells odd, sounds strange, or isn’t keeping your house as warm as it used to, get in touch with us right away.
