Heating and Air Conditioning questions, answered by experts

Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.

If you’re planning an AC replacement, choosing an AC with a higher SEER rating may save you money in the long run. Tax credits could cover as much as 30% of the job, and you’ll notice smaller utility bills (particularly if you live in a hot climate where you need to constantly run the AC). Generally, you can expect to pay between $350 and $1,500 for each SEER rating increase. Weigh the cost against your typical utility bill to figure out what’s worth it to you.

HVAC pros recommend that you replace your AC filter every one to three months to maintain optimal indoor air quality and ensure your HVAC system operates efficiently. However, factors such as filter type, household size, and environmental conditions may influence the frequency of replacement. Regular filter changes help prevent debris buildup, maintain airflow, and prolong the life span of your air conditioning unit.
