Read on to learn more.

1. Fluctuating Energy Bills

AC units use about 6% of all electricity produced in the US. Take a look at your energy bill. Does the amount seem to fluctuate year-over-year?

If you’re noticing major jumps in your energy bills, consider HVAC repair services. You can improve your unit’s energy efficiency to cut costs. Otherwise, there’s a chance your unit is working harder than necessary to expel cool air.

It could break down sooner than expected as a result.

2. Constant Breakdowns

Is your AC not cold? Does it seem to break down too often? You might need to call someone who can fix air conditioners.

They might realize there’s a bigger issue with your unit.

Consider scheduling preventative maintenance checks. An HVAC technician can review your unit once a year. They can detect any small issues before they become big, costly problems.

3. Strange Noises

Take a moment to listen to the noises throughout your home. You might hear:

Rattling
High-pitched whistling
Loud pops
Humming
Buzzing
Metal clanging

These sounds could indicate there’s an issue with the AC ventilation. For example, a loud pop might indicate a clogged filter. If you hear whistling, it could mean a blocked duct.

4. Failure to Cool

Is your AC not cold? If the unit isn’t producing cool air, it could indicate a number of issues, including:

Condenser issues
Duct leakage
Leaking refrigerant
Low refrigerant

Consider calling an HVAC technician right away. They can improve your AC ventilation before the unit breaks down completely.

Otherwise, dirty coils, a sluggish fan, or other issues could impact your unit’s ability to function properly. There’s a chance cool air isn’t circulating through your vents. The HVAC unit will work twice as hard to try and achieve desired temperatures.

Your energy bill might start to rise as a result.

5. Allergy Flare-Ups

Have your family members started sneezing and sniffling more often than usual? It’s likely allergens are filling your air. Make sure to check your air filter.

It’s important to change your filter every three months. Otherwise, dust mites, dander, and pollen can build against the filter. You could start breathing in those allergens.

Meanwhile, the unit will have to work twice as hard to push clean air through the dirty filter. Replacing your filters regularly can help you avoid costly repairs.
