Great & speedy service with most knowledgeable tech.




Parts are on order and furnace is working for now, parts to come next week. Dan explained things in terms I could understand and am following his recommendation to the letter. May be pricey, but get only what you pay for today.

Very pleased with the service




We were happy with the service provided and the explanation of our problem with our AC and then having the manager come out to also take a look to see if he agreed with the issue. Nice to know they have our back.

Boiler would make a whiny noise. I cycled the boiler. When it had an output of 150000 btu the exhaust blower shroud would vibrate and make a noise. I removed the shroud. We will need to order a new exhaust blower and come back to install it. The boiler is heating at this time.

No heat on oil furnace. The burner was locked out. I checked the cad cell, it was good. Checked clean outs, they were clear. Cycled burner. The burner would try firing but it wasn’t getting constant oil flow. I bled air from the oil line. Cycled the furnace multiple times. It’s heating properly now. No charge since I just cleaned it and forgot to bleed air out of oil line.

No heat on geo unit. I checked unit for fault codes. Found a flow switch fault code. I cleared the code and cycled the geo. It cycled through hydronic heat normally. I checked the flow switch, found it wasn’t aligned correctly on the pipe. I corrected the flow switch alignment. Checked flow center water level. Water is to the top. Level is good. Cycled geo in forced air heat. It’s working properly.

Performed air conditioner clean and tune. I checked the filter and blew out the drain. Performed a leak search on the system. I found the evaporator coil was leaking refrigerant. I cleaned out and tested the electrical components. Washed the condenser coil. Cycled the system and checked the refrigerant charge. The air conditioner is getting low on refrigerant. Dan will be out to verify the leak and give options to move forward. Unit is 13 years old, average life is 12-15 years.

The 2nd stage cooling wasn’t working. Found the thermostat wasn’t working properly. I replaced the thermostat and connected to the WiFi. Also found the drain wasn’t trapped. I put a trap in the drain line. Cycled the geo it’s cooling properly at this time. This is covered under warranty.
