Preventative HVAC Maintenance Steps




HVAC, (Heating, Ventilation, and Air-Conditioning) is the system that helps you to maintain a comfortable temperature in your home. It also helps you to maintain optimal air quality and energy efficiency.


There can be a lot of things that can go wrong with your HVAC system, including leaks,

corrosion, and issues with distributing hot and cold air. And everything from clogged filters to dirty coils can lead to a problem and shorten the life of your system. So you must take

preventative steps to maximize the efficiency of your HVAC system.


As a homeowner, there are a lot of responsibilities you have to take care of, and things like

HVAC maintenance might not be particularly glamorous. But this is a part of keeping your home running right and homeowners have to take preventative maintenance steps to avoid issues with their HVAC systems in the future.


The best way to maintaining your HVAC system is to have a set plan that you follow every year. In this guide to HVAC maintenance, we will go over the basic maintenance steps that you need to know to run your HVAC system properly.



5 Preventative HVAC maintenance steps:


1. Clean or Change the filters:

This is the most important step that you have to take care of to prolong the life of your HVAC

system. Regular cleaning and changing your filter are essential for the effective performance of your system. Clogged filters most certainly affect your system's efficiency and capacity.

When to change the filters?

The general rule-of-thumb is to replace the filters of your system every 90 days. If you have pets in your home or some allergy problems then we suggest you change the filters every 45-60 days.


2. Clean Condenser and evaporator coils:

When your unit sits outside, it gathers various dirt particles and coils can become clogged and freeze over. Dirty coils can affect your HVAC system's performance in the same way a clogged filter does.

How to clean coils?

First of all, turn off your AC at the thermostat and shut off the electricity to the HVAC system.

Then remove the evaporator coil access panel to access the coils. Using a can of coil cleaner

sprat it directly on to the coils evenly and thoroughly to clean them.


3. Inspect ducts for mold, dust, and debris:

Make sure you keep the outdoor unit clean of dust, grass clipping, and weeds so that it can

breathe properly. Look at the air handler, supply vents, and any visible areas of ductwork for evidence of debris, dirt, or visible mold.


4. Replace worn belts in the air handler:

The belt on the blower of your air handler will need replacing occasionally (every three years). Turn off the power to your system before changing the belts. Do not just pull the old belt off the system, it can damage the shaft or the motor of your air handler. You can also use a marker to mark the location so that it can be set to its original position.


5. Clean Blowers:

An indoor blower pushes the air out of the system. It may be sound like your system is on, and the motor might be running, but when the blower is dirty, air does not come out the way it should. Frequently check for dust collection to avoid any blower blunders.


If you would rather not take on the above-mentioned steps of HVAC maintenance on your own, please do not hesitate to call the professionals at air handler systems.
