Most Homeowners Don’t Know They’re Making These Common HVAC Mistakes
HVAC techs see it time and time again. They show up at a home to address an HVAC emergency to find that the homeowners are surprised that something is wrong. They think they do everything right to keep their HVAC system running smoothly and operating efficiently. Unfortunately, this is not the case much of the time. The homeowners may think they’re doing everything right, but they’re often misinformed or have simply adopted bad habits. To start the year off right, this article will clear up any doubts and steer homeowners in the right direction when it comes to good and bad HVAC habits.
Utilizing the Wrong Air Filter
There are a couple of different ways homeowners go wrong with air filters. The first is by using the wrong size filter. Even a slightly smaller air filter can make a world of difference in terms of air quality. It’s a no-brainer that homeowners want the best quality air possible in their homes, and the correct size air filter helps to make this happen. The filter should fit snugly into place and shouldn’t have much space around the sides at all. When in doubt, homeowners should measure their filter’s holding area to make sure they have the right size.
The second way to go wrong with air filters is the MERV rating. This is the Minimum Efficiency Reporting Value, and it ranges from 4 to 12 for residential filters. However, using a filter that’s too thick can stress the system, while using one that’s too thin can allow pollen, dust, and other airborne pollutants into the home. Homeowners should consult an HVAC professional to find the optimum filter for their system.
Forgetting Regular Maintenance and Inspections
It’s easy to forget or dismiss regular maintenance and inspections. But doing so regularly can be a costly mistake. HVAC systems need to have maintenance and inspections done at least twice a year, typically in the spring and fall. This allows homeowners to stay ahead of the curve by catching small problems before they turn big.
When the system isn’t cared for properly, it tends to have a snowball effect. Pretty soon, everything is breaking down, and the costs are skyrocketing. Plus, visits from a professional tech can help homeowners ensure that they have the proper filter, that their thermostat is set for maximum efficiency, and that the entire system is running smoothly.
Not Having a Professional Work on the Unit

Lastly, the bad habit of not hiring a professional to work on the system is a huge mistake. By hiring a professional company that is certified and insured, homeowners protect themselves and their biggest investment: their home. The “handyman” or “uncertified” company may have cheaper rates, but there’s definitely a reason for it. Hiring professionals who specialize in HVAC and have the certifications to show for it will ensure the job gets done right the first time.
