Improve your Furnace's Performance

Your furnace's performance is dependent on every component working to full capacity, so before you start shopping, check to see that your thermostat is properly programmed, your duct work is sealed, and your attic and walls are properly insulated. If those components aren't working as they should, you won't notice the benefits of your new furnace and will continue to see high bills without enough warmth.

In addition to the money you'll save in utility bills, a new furnace will also come with a valuable warranty that will protect you from paying money for service calls over the next several years. Today's furnace systems are also safer than they were in the past, so you and your family can enjoy the peace of mind that comes from knowing your home is safe.
They were wonderful, from the owner, Mr. Popp, Kristen in the office and both of the young men who installed my new heat pump, they were professional, friendly and more than knowledgeable. I have heat and it's wonderful. I would highly recommend AJR Heating Air Conditioning and Refrigeration for any one needing their help.
