Most homeowners don’t have the HVAC knowledge to repair their heating and cooling systems, but they can still be proactive about preventing HVAC repairs by creating an HVAC preventative maintenance sheet. Once created, homeowners can use a preventative maintenance sheet to carry out their own maintenance, or use it as a checklist for when HVAC professionals perform maintenance. If you want to create your own maintenance sheet but you don’t know where to start, we list some critical aspects of HVAC maintenance that you should place on your list.

1. Inspect Blower Assembly

A blower assembly includes a blower wheel, blower motor, and the assembly that houses them. The chief concerns with blower inspection are three: ensuring the assembly is free of dust and dirt; ensuring the fan belt is in good condition; and lubricating the assembly by applying oil to oil ports. Because a blower is what moves air through your dwelling, ensuring its good condition is critical to maintaining temperature control.

2. Inspect Evaporator Coil and Related Equipment

When evaporator coils become clogged with dirt and debris, they can malfunction, causing your air conditioner to run non-stop or not run at all. Cleaning an evaporator coil is a delicate job that can usually be done with water. After inspecting the coil, make sure that the condensate drain pan and drain lines are free of dirt and debris as well.

3. Inspect Air Filters

Clogged air filters are one of the biggest causes of frozen evaporator coils, and they can also become so clogged that they (1) cause your blower to work harder than necessary, making it more prone to breakdown, (2) cause your home to have dust ridden air, and (3) decrease your home’s force of airflow. If you have a central blower, changing the air filter is usually as easy as removing a small panel, sliding the old filter out, and sliding the new filter in.

4. Inspect Flue System on Central Heating Furnace

One of the biggest reasons why central heating furnaces fail to deliver the proper temperature is leakage where the flue connects to the furnace. Perhaps the easiest way to check for leaks in your flu is with smoke pencils, which use smoke to detect the slightest air leakage. If you find that that your flu has a leak, having an HVAC technician do a professional repair job is recommended.

Trusting the Professionals for Your Repairs

While some homeowners opt to perform their own HVAC maintenance to the extent that they can, HVAC repairs should always be left to the pros, especially considering the potential danger of some repair jobs, such as gas furnace repair. Hiring a professional HVAC technician for repairs will do more than ensure repairs are done safely and effectively; it will also prevent new problems due to amateur repair jobs, which could easily cost thousands of dollars to repair. When shopping for an HVAC contractor, always hire a contractor that is licensed, bonded, insured, and whose record at the Better Business Bureau shows no unresolved customer complaints.
