Maintenance of your heating and air conditioning system is important to ensure it continues to work efficiently. Regular maintenance will help prevent sudden breakdowns and costly repairs. Here are some common signs that your HVAC system needs maintenance.

1. Increased Energy Bills

Up to 70 percent of a home’s total energy costs go towards heating and cooling, so if you’ve recently seen a spike in your energy costs, there’s a good chance your HVAC system is working overtime to heat or cool your house. To prevent continued high energy bills, it would be wise to call an experienced HVAC technician to diagnose and fix the problem before it gets worse.

2. Inconsistent Temperatures

Uneven temperatures throughout your home might signal an issue with airflow or thermostat calibration. At your next maintenance appointment, be sure to point out any noticeable hot or cold spots to your HVAC technician.

3. Unusual Noises

Strange banging, rattling, or squealing noises usually indicate that your system has a mechanical problem such as loose parts or motor issues. If you hear a noise that concerns you, call your HVAC company right away.

4. Low Airflow

If there is little air blowing through your vents, you should first always check your air filters. Dirty filters may be the source of your issue, and for most homes, replacing or cleaning air filters is a simple and inexpensive household task. 

If the problem persists, your system may be suffering from a bigger issue such as clogged ductwork or a rusty compressor. Call your HVAC company to determine the cause of the reduced airflow.

5. Short Cycles

How long your unit runs to reach your desired temperature depends on many factors: the size and condition of your unit, the size of your home, the temperature outside, your desired interior temperature, and home insulation quality, to name a few. As a homeowner, you should familiarize yourself with the length of your unit’s cycle. That way you can recognize if your system begins turning on and off too frequently. 

Short cycling could be an indication of an improper thermostat, malfunctioning sensor, or an overworked system. Your HVAC company can help identify the issue and get your system running properly again.

6. Bad Odors

You deserve fresh, clean air in your home, so any unexpected odors coming from your vents, such as musty, burning or other foul smells, could be cause for concern. Common problems that result in unpleasant odors include mold growth, electrical malfunctions, or system components that have burnt out. Let your HVAC company know of any smells you’ve noticed in your home.

7. Excess Humidity

If your home feels muggier than usual, it indicates that the HVAC system isn’t removing humidity as well as it should. While a dehumidifier may improve your comfort, you should still have your heating and cooling systems looked at to prevent greater issues from developing.

8. Bad Air Quality

Dusty, debris-filled, or allergen-loaded air may indicate that your system’s filters or ducts need cleaning or replaced. Your HVAC company can help improve the air quality in your home.

9. Water Leakage

Pooling water in the area around your HVAC unit may indicate a clogged or damaged drain tube. Leaks can cause serious damage to you home, so contact a trusted HVAC professional as soon as possible

10. Aging System

As HVAC systems get older, they naturally decrease in efficiency and are much more likely to develop issues, requiring much more maintenance. If your system is more than 10 years old, make sure you schedule regular maintenance appointments (twice a year is recommended) to catch potential problems before they happen.

If any of these issues have been occurring in your home, now is the best time to have your HVAC system serviced.
