An efficient working HVAC system is most desirable in a home. The comfort that comes with having sufficient heat in the winter and a flow of cool air in the summer cannot be overrated.
However, this is dependent on a number of factors. The first being the consistent maintenance of the system and another is the system’s inspection on a regular basis. HVAC inspection is recommended as a twice a year service. This can identify minor issues that may escalate into major problems in the future with a much higher cost to fix.
HVAC inspection should be conducted by a professional. A homeowner DIY inspection is limited to eyeballing the system and doing simple clean up jobs. A comprehensive inspection is handled best by professionals who prepare a report with recommendations on how best to improve the system, increase its productivity, and fix any highlighted issues.
The different components of an HVAC system that require inspection are as follows:
1. Air Filters
The air filter in these systems ensures that the air returning to them is cleaned. These are the easiest components that make up the system that is easiest and most obvious to inspect. Air filters should be free of dust and dirt. The filters should be cleaned or replaced at least once every couple of months.
2. Ductwork problems
A visual inspection of exposed ductwork found in the basement or attic is conducted. Items that are looked for include loose fittings around seams, streaks of dirt that are indicative of escaping air from the system, dents on the metal, as well as sections of the flex ducts that may have collapsed or are torn.
3. Furnace flames
HVAC inspection includes a furnace check. Ideally, the furnace flames are supposed to be a steady blue and not a flickering yellow. The inspector will fire up the furnace and assess the flame,
4. Grills and registers
The HVAC grill and registers are inspected for dust, dirt as well as pet hairs that may end up obstructing the flow of air into the system. The registers should be opened and shut to ensure they operate smoothly.
5. Air Conditioning Compressors
Compressors found outside the house will be inspected as well. The air conditioning compressors should be unobstructed by things like shrubs and vines. The units should also be checked for any kind of tilt and their fans to be undamaged. Any bent blade should be repaired or replaced .
The thermostats will also be checked by removing their covers and cleaning them from any dust or debris.
