HVAC Maintenance

Around 42% of homeowners say they call a professional HVAC service to perform routine maintenance on their equipment.

Every HVAC system is an investment so it’s important to properly look after them and recognize when they need to be fixed. Perhaps you’re unfamiliar with the process and want to learn more about HVAC maintenance.

If that sounds familiar, you’ve come to the right place. Here’s everything you need to know.

What Is in an HVAC System?

Before diving into the HVAC tips, it’s important to understand what’s in the system. If you don’t know, HVAC stands for heating, ventilation, and air conditioning which are installed in both residential and commercial buildings. We need HVAC systems because they provide better indoor air quality and heat or cool our homes depending on the season.

Common HVAC Problems 

Not sure how to take care of an air conditioner? Know there is a list of HVAC problems that you should look out for. Once you pinpoint an issue, you can either fix it or hire a professional to help you. For instance:


Your system may leak depending on the connection of the HVAC connector and drain line. If this happens, your system will work in overdrive and break a component that you must replace.

To prevent this, check the refrigerant lines and make sure there are no leaks from the AC condensate line.


It’s also a risk combining wiring with moisture because there’s a chance of corrosion. This could happen anywhere in your HVAC system especially on wires or terminals and cause it to turn on and off on its own. Like leaks, this will force your system to work harder and in some cases, cause it to break down.

Dust and Debris

When you undergo air conditioner maintenance, check whether there’s any debris caught in between the wires or the electric panel as it’ll stop your system from running efficiently. Plus, grimy air filters will pump dust and allergens into your room thereby reducing the air quality.

Regular DIY Maintenance

One of the most important AC tips is to conduct several mini maintenance sessions in between formal visits. For instance, swap out the filter every month especially when the unit’s indicator light flashes as it means the airflow is blocked. Instead, get high-efficiency filters as it’ll save you money in the long run. 

You should also remove debris or dust from your outdoor unit and trim foliage so it can’t get caught in the system. As a general rule, make sure there’s nothing within two feet from your outside unit. 

For additional AC maintenance, check that the refrigerant lines aren’t leaking and clean the condensation drain line with bleach so there’s no debris clogging it. If you’re not sure whether your unit needs service, check out this post

Maintenance Professionals Help With

Homeowners can handle superficial tasks but it’s important to hire a professional to thoroughly service your HVAC system. Heating and cooling units are complex so you’ll need an expert. The technician will check the intricate details like checking every component is running smoothly.

Further, HVAC pros will check the thermostat so that your household is comfortable in every season. They’ll also tighten loose electrical connections, lubricate moving parts, and check that the condensate draining runs away from your property.

The maintenance check also includes adjusting the blow, cleaning the evaporator, and ensuring the gas pressure and heat exchanger are working well. If you’ve got a new system, get it professionally checked once a year whereas older units need to be maintained twice a year, mainly in the spring and the fall.

Benefits of Annual HVAC System Maintenance 

A major advantage of signing up for a regular maintenance plan is lower energy bills. If your system isn’t functioning properly, it’ll take more energy for your home to heat or cool. But when it’s regularly maintained, you’ll save money because the HVAC won’t require as much power. 

You won’t have sky-high repair bills either. This is because a technician can notice problems before they happen so you’re not lumbered with expensive repairs or paying for new parts. You’ll also have peace of mind knowing that the system won’t crash in the middle of a winter’s night. Plus, you won’t have to pay extra for an emergency fix. 

Another important benefit of regular HVAC maintenance is that it keeps your family safe. If you’ve got a family member who suffers from asthma or allergies, your HVAC system’s filter must be pumping clean air into your home instead of dust or mold. 

An ancient HVAC system may have a dodgy component that may short circuit and break out into a fire, especially hazardous if you have children. And if you have a separate furnace that hasn’t been maintained, it may develop problems like carbon monoxide which can have fatal consequences.

That’s Everything About HVAC Maintenance

Now you know the benefits of HVAC maintenance and what to expect during the process. 

Regardless of how old your system is, it’s important to regularly check the outdoor unit for debris and make sure there are no leaks. Then, hire a technician for an annual inspection as they have the knowledge and equipment to handle complex problems.

Otherwise, your unit may be faulty and cause an accident so it’s safer to sign up for a maintenance plan. Good luck!
