Keep Your Heating and Cooling System Healthy Year-round with Proper Maintenance

At this point in the year, many homes in the U.S. have their heating systems back in action. The start of heating season is a notoriously busy time for HVAC contractors, as homeowners discover issues with their systems or are reminded of problems they put off in the warmer months. For homeowners, this can mean delayed service due to packed schedules, or out-of-stock parts due to high demand, leaving them uncomfortable.

But there’s a better way. Properly maintaining your heating and air-conditioning equipment allows you to enjoy a healthy system without the stress of unexpected repairs or poor performance next time heating season comes around.

Here are some tips to keep your systems running smoothly all year long.

Schedule A Check-Up

Even if there’s nothing wrong with your system, bringing a contractor out to check on things before the heating season starts can make a big difference. Your contractor will ensure everything’s running smoothly. Small ductwork leaks or loose parts in your ductless units may seem innocuous but can grow into bigger issues if left unrepaired.

Some things are best left to professionals, and your system’s annual tune-up is one of them. Contractors will notice and resolve potential hiccups the typical homeowner may overlook.

Ideally, they’ll give your system two thumbs-up and leave you with greater peace of mind.

Clean Those Filters

Here’s something you can do, homeowners: take care of your filters!

No matter what type of heating and air-conditioning system you have, replacing or cleaning your filters routinely is an important part of keeping your system healthy.

Our multi-stage allergen filters do a great job removing contaminants and odors from the air while also trapping dust, pollen and other particles. Still, they need to be cleaned routinely and kept in good shape to be effective. A dirty filter is bad news for your indoor air quality and your system’s performance. Fortunately, most Mitsubishi Electric units have removable, washable filters to make taking care of them a no-sweat, no-stress job.

Protect Your Units

Taking a few simple steps toward protecting your system can go a long way. Your outdoor units should be kept clear from vines and weeds, and if you live in a snow-prone area, additional measures like snow hoods and stands can help lengthen units’ lifespans.

You can help keep the indoor unit clean by wiping the surfaces and making sure nothing is blocking the airflow. Your contractor will inspect the working components inside and clean them as needed. Fortunately, when it's time to upgrade, our new models have a built-in protection against build-up.

For example, our Deluxe Wall-mounted indoor unit features our patented Dual Barrier Coating applied to the heat exchanger, vanes, air duct and blower wheel. The coated surfaces repel contaminants, simplifying system maintenance and helping ensure indoor units run smoothly without collecting damaging particle build-up.

Time for an Upgrade?

Making thoughtful decisions for your system’s longevity can improve year-round performance. However, if you’re struggling with your conventional system’s issues year after year, the time may be right for an upgrade.
