Ac maintenance should at minimum include a full inspection of the electrical components including amp draws and voltage readings, capacitor readings, refrigerant levels, super heat and sub cooling, condenser and evaporator temperature differences and airflow readings.
It is also a good idea to back flush the outdoor condenser coil and clean the condensate drain line at the indoor unit. Usually you would expect to get a discount on AC Repairs in Frederick
Heat pumps should have these same services performed in the spring.
A yearly combustion analysis should be a part of every gas furnace inspection. Also a thorough visual or camera inspection for holes or cracks of the furnaces heat exchangers.
Other readings should include testing for proper gas pressure, taking flue draft readings as well as testing for Carbon Monoxide. An often overlooked part of a furnace inspection is inspecting the furnace flue or chimney. It is very common to be in need of cleaning or repair.
Testing safety switches such as the furnaces high limit, draft safeguard and pressure switches.
Testing electrical components such as the blower motor, inducer assembly and capacitors.
Testing for proper airflow and heating temperature differential.
Heat pump maintenance should include a full inspection of the electrical components including amp draws and voltage readings, capacitor readings, refrigerant levels, super heat and sub cooling, condenser and evaporator temperature differences and airflow readings.
The defrost cycle and auxiliary heaters should be tested.
It is also a good idea to inspect the indoor coil and clean as needed.
Most humidifiers require a yearly replacement of the water panel. They should also be cleaned of scale and tested for water leaks.
The humidifier control or “Humidistat” should be tested for accuracy and also the water supply opened before each heating season.
