Very happy with service- very prompt- courteous technicians- did a great job

The owner of the business couldn't have been nicer- he had been recommended to me by my neighbor who was also very happy with the service and product. The technicians showed up promptly- they were very courteous and very informative. They did a great job- and checked and rechecked everything. I have already recommended them to another neighbor.

Performed Precision Heating Tune Up on Oil Fired Furnace. Replaced 16x20x1 Air Filter. Furnace had a washable filter installed in the Blower Cabinet also. Removed the washable filter from the unit as it is not needed with the replaceable filter. Replaced Oil Nozzle and Pump Strainer. The oil line does not have an oil filter installed on it. Would recommend installing an Oil Filter on the system to help keep debris and dirt from getting into the the Oil Burner and Pump. Cleaned Flue Pipe, Chimney Base, and Heat Exchanger. Put system in operation and performed Draft Test, Smoke Test, and Combustion. Measured Air Temperature readings on Oil Furnace. System is a hybrid heat pump/oil Furnace. Switched over to heat pump and measured Air Temperatures. Measured a 25 Degree Split on the Heat Pump. Performed Heat Pump tune up on the second system. Replaced 16x25x1 Air Filter. While testing system, found outdoor unit was going off on high pressure. Removed refrigerant from the system to test wh

Returned to site to install a new Humidifier. Disconnected and removed existing Humidifier. Installed new Aprilaire 600M Bypass Humidifier. Ran new Water Line and installed Control above Humidifier. Ran new Wiring to Furnace and wired into system. Sealed Humidifier around ductwork. Cleaned Condensation Pump and blew through vinyl tubing. Condensation Pump was extremely dirty and does not have a safety float. Filled pump multiple times to test operation. Due to how dirty condensation pump was and not having a safety float replacing with a new Pump is highly recommended. Spoke with homeowner about concerns and included an Estimate for replacement. Turned heat on and tested Humidifier. Set control to 35% upon completion.

Service call that the Heat Pump was running non stop. Upon arrival found thermostat set to 65 Degrees and temperature was satisfied. Turned temperature up to test operation. Measured air Temperatures and was measuring about a 15 Degree Temperature rise. Checked refrigerant pressures and system appeared to be low on refrigerant. On previous visit had added refrigerant and leak dye to system. Used UV Light and searched indoor and outdoor unit for signs of a leak. Could not find any leak point in the system. To get system back up and running began adding refrigerant to system. Found the Suction Refrigerant pressure was not increasing and the high pressure was rising. The Outdoor TXV is restricted and is not allowing the proper amount of refrigerant to flow through the system. Will need to replace TXV for the system to operate properly. As system needed refrigerant charge on last visit, system may also have a leak that would be an additional repair once the leak point has been determined.

Checked no heat complaint, found furnace switch off on first floor furnace, turned on, furnace started and ran. Checked air filter, getting dirty. Checked operation ok. Checked second floor furnace found furnace switch off. Turned furnace on, could heat banging coming from the furnace. Checked furnace, found off on limit. Reset limit. Furnace tried to light but a large flame roll out occurred. I can see soot in the primary heat exchanger. I recommend replacing furnace due to to scooted and restricted heat exchangers. Shut furnace off until repairs are made no heat on the second floor at this time.
