The HVAC system in your home is a crucial piece of equipment that needs regular maintenance. Performing these inspections can help to keep your unit functioning efficiently throughout the year and help it last longer. If you have a limited budget, there are ways you can perform your own inspections.
Turning Off The Power
When it comes to HVAC inspections, the more proactive you are, the better. This can save you money in the long run by preventing costly system breakdowns and energy spikes. Before beginning your DIY HVAC inspection, turn off the power to the unit. You can find this in the service panel or by removing the main breaker. Afterwards, unplug the unit.
Removing The Access Panel
In order to do a good job of inspecting your furnace, you must be able to remove the access panel. This allows you to see the fan and the fan motor. To do this, you’ll need a power drill and a 3/8-inch drill bit. After that, you’ll need a good pair of pliers to remove the screw. You’ll also need a jigsaw and some paper to trace the duct’s outline. Next, use a wet/dry vacuum to remove any leaves or debris that may have made their way inside of the fan cage. Also, clean the fins with a sprayer hose and gentle stream of water.
Removing The Evaporator Coil
The evaporator coil is usually attached to the furnace and can be accessed through an access panel. This panel is typically removed with a nut driver or screwdriver. Once the panel is removed, spray a no-rinse evaporator coil cleaner on all exposed surfaces of the coil. Let it sit for a few minutes, then wipe away any excess debris. Reapply the cleaner as needed, until it’s fully clean.
Removing The Evaporator Drain
If your unit doesn’t seem to be running well, it could be due to a clogged evaporator drain line. If the clog isn’t removed, it could affect the efficiency of your system and lead to expensive repairs down the road. Clean your evaporator drain line regularly so that mold, algae, and bacteria can’t develop into clogs. This can save you money on expensive AC repairs down the road.
Removing The Air Filter
Air filters help filter out dust, dirt, pollen, dander, and other airborne debris from entering the furnace unit. They should be changed every three months or so, depending on the type and how frequently the family uses the system. Most systems have a removable air filter access door in the return air duct near the blower. Some also have a vent in the ceiling that houses the filter.
