Our Reviews by City
Heating repair: no heat main floor system zone. Found no signal from the thermostat to the system. Bypass thermostat to test and system came on and shut off. Replaced flame safety sensor and system came on. Thermostat did not send a signal to the furnace to operate. Reset thermostat and now working normally. Suggest replacing the thermostat.
2 system furnace prepaid preventative maintenance service. Replaced filters, checked electrical and safety switches all ok at this time. Both systems need a combustion calibration, to get CO levels within safe range. Both systems heating normally.
Installed Guest room HVAC system
3 heating system preventative maintenance check complete. Changed upstairs and guest house filters. Found guest room system shutting off on low-pressure lockout due to it being void of refrigerant. Having no refrigerant in the system indicates a major leak. Recommend upgrading system. Found main level/ upstairs furnace with very high, unsafe levels of carbon monoxide, recommend recalibration to reduce co levels down to safe levels. The furnace also has a worn ignition system and weak blower motor controller. Basement system is also going off on low pressure due to it being void of refrigerant. Replaced blower motor controller and ignition system, and recalibrated CO levels from 133 ppm down to 22 ppm.
