The regular maintenance visit of an HVAC technician is not complicated or even long, but it is unmeasurably important.
The inspection will be scheduled months in advance and it is good to have an inspection two to four times a year.
The HVAC technician will always check the filter in both your furnace and air conditioner. This is a small matter yet it can save you from a load of trouble. The technician will also check to make sure all moving parts are well lubricated and moving the way they should. Fans and vents will be checked to ensure there is no leakage, bends, or rust. He will then check the thermostats and thermometers to ensure that they are in sync and not costing you more money than necessary. Sometimes the thermometer will break and need to be replaced altogether. Next he may check all wiring to ensure there are no disconnects or damage to them. To ensure that the HVAC system will continue to produce heat and cool air the HVAC technician will inspect the heater and coolant levels and consistency. If repairs need to be made, the technician will talk with you first and make sure you are ok with the cost and his decision. Repairs may take anywhere from a few minutes to a few hours depending on the size of the repair. The goal of these small HVAC maintenance checks is to avoid a large problem like a system shut down. Nevertheless, in some circumstances, large problems will come anyway. Overall, an annual HVAC checkup will do you more good than harm for the long haul.
