Professional and reasonable prices

We've been using DiBiase for several years. They've always had competitive prices and are very professional. Brian was out today to perform a checkup. He was here almost an hour, and he appeared to actually do things. He's friendly and kept things clean.

Installed EZ trap that’s ran to a condensate pump and vinyl tubing ran into sewer drain. Installed media filter aprilaire 413 filter. Ran new gas pipe to connect existing gas line and all copper brazes have been pressure tested and put unit on vacuum. Ran tests on unit and ran in heat and cooling. Added charge and adjusted gas pressures.

Cleaned outdoor coil for second floor unit, after cleaning coil check operation of heat pump found system to be low on refrigerant, next step is to find where the refrigerant went, we need to add refrigerant and dye so we can find out where is the refrigerant leaking, manufacture does it cover the cost of refrigerant and dye, customer approved adding refrigerant and dye, we will check for leaks next time we came back for tune up, also check older first floor unit, found unit to be slightly low on refrigerant r22, it is not low to the point where is not cooling, but system is loosing capacity and efficiency, would recommended system replacement we will provided an estimate to replace system

Started propane furnace, after burners light I see the top chamber of the heat exchanger have flame roll out. Checked venting ok. Blew out condensate trap. Heat exchanger is restricted and must be replaced. Recommend replacing furnace. Furnace needs a heat exchanger furnace is installed in attic between truss and has no room to be removed. Recommend replacing furnace. Will have heat until roll out switch trips again
