The Importance of HVAC Preventative Maintenance

Here are 6 reasons why HVAC Preventative Maintenance is so important.

1. Saves You Money

Here are the ways preventive maintenance benefits your family’s bottom line.

  1. Prevent costly breakdowns
  2. Reduce your energy bills
  3. Extend the life of your HVAC system
  4. Keeps you protected under warranty

Regular HVAC maintenance can reduce the risk of costly breakdowns by as much as 95%. 

Chances are you would never drive your car for 30k miles without getting an oil change; you’d be looking for trouble. 

This holds true for your heating and cooling system too. 

Cut your energy bills. 

Preventive maintenance helps to ensure your HVAC system runs at peak efficiency, which can mean a savings of up to 30% on your energy bill, according to the U.S. Department of Energy. 

Extend your system life  

Regular preventative maintenance extends the life of your system, reducing the chance that you’ll need to spend big money on an HVAC repair soon. 

It’s like how annual checkups can help us be healthier and live longer, except your HVAC Dr. makes house calls. 

Stay covered under your warranty.

It’s important to know that most HVAC manufacturers require proof of annual maintenance when a repair claim is submitted under warranty.

Some of the components that make your HVAC system work can be expensive, so investing in annual preventative maintenance to keep them covered under your warranty can save you a significant amount should something goes wrong.

2. Improves Your Air Quality

The EPA reports that the indoor levels of airborne pollutants in your home maybe 2-5 times higher (in extreme cases more than 100 times higher) than outdoor levels – even in the most polluted urban areas. 

This is even more significant if you or any family member suffers from respiratory issues, such as asthma. 

Though we are not aware of it daily, we share our homes with a variety of substances that we would rather not breathe in. 

These common indoor allergens range from regular household dust that can contain dozens of respiratory issues to pet dander, dust mites, cigarette smoke, pollen, mold, and more.

If a musty odor in your home has you concerned about mold, it may be time to have the air ducts professionally cleaned. 

Preventive maintenance helps ensure the warm or cold air pumping through your home’s vents is as clean and as well-filtered as possible. 

3. Improves Your Home’s Comfort

You depend on your HVAC system to keep your family comfortable year-round.

Regular preventative maintenance helps your system distribute and produce warm and cool air more steady and even. 

It also reduces the chance that you’ll come home from work one cold winter day to find frigid air pulsing through your vents. 

It can be easy to take maintenance for granted or get used to the idea that a particular room is just too hot in the summer or chilly in the winter.

Preventive steps like cleaning your ductwork can help ensure that your home heats and cools as evenly and efficiently as possible.

Regular maintenance will also minimize the chances that HVAC noises or smells will disrupt the comfort of your home. 

4. Keeps Your Home Safer

I’m sure you’ve heard the horror stories. 

Someone you know went away during the holidays and returned to find a frozen and severely damaged house. 

If you’re away from home and your heat stops working during a cold snap, the result can be a domino effect of frozen or burst pipes, extreme water damage and even worse. 

The cost of the repairs in this situation can be excruciating.

Preventive maintenance also helps safeguard your family against the risk of carbon monoxide – the colorless, odorless gas whose effects can be deadly.

According to the Centers for Disease Control, exposure to even the lowest levels of carbon monoxide can cause serious health issues. 

The most common cause of a carbon monoxide leak is a cracked or failed heat exchanger.

An HVAC maintenance checkup typically includes a carbon monoxide test that would detect any potential hazard in your home.

Your HVAC professional can also talk to you about the benefits of installing a carbon monoxide detector.

5. Helps the Environment

For those concerned about their green footprint, keep in mind that a well-maintained HVAC system consumes considerably less fuel – and that’s good for the planet. 

Such homeowners will also want to be aware of what kind of refrigerant is used in their system since the EPA has been working to phase out substances that harm the environment. 

HVAC technicians handling controlled refrigerant are required to have EPA Section 608 Certification. 

They can help you understand what kind of refrigerant you’re using, its impact on the environment, and your options.

Your HVAC contractor can also talk to you about the benefits of using a programmable thermostat or switching from oil heat to natural gas so you can take to reduce your system’s impact on the environment. 

6. Gives Greater Peace of Mind to Your Family

Finally, investing in a preventive maintenance plan gives you the comfort of knowing that if something goes wrong, you’ve already taken steps to make the situation as safe and painless as possible.  

This air conditioner coil, located inside the home near the furnace, was so plugged with filth we had to remove it, and acid wash it clean.
