You know you need AC repairs when your air conditioning system is not producing the cool air it should. This can lead to several problems that will make your life miserable, such as uncomfortable temperatures in your home or office, high energy bills due to the constant use of the unit, and potential health risks. Thankfully, there are some warning signs you can look out for that may mean you’re on track for an AC repair. Keep reading to learn more about three signs you need AC repairs today!

1. A Funny Smell

Does the air coming out of your vents smell funny? If you detect a strong, pungent odor when you turn on the unit, there could be something wrong with it. Odors like these can originate from mildew or mold inside the ventilation system, leading to serious health issues.

The smell could also be caused by burning electrical components. Switching off the unit is necessary if you notice this smell. You should never attempt to clean or repair it yourself – contact HVAC contractors so they can diagnose the problem.

2. Odd Sounds

Does your unit make strange sounds when it’s running? If you hear loud, unusual noises coming from your HVAC system, there could be something wrong with the hardware. High-pitched whistling, popping, gurgling, or rattling noises are all signs there might be a problem. HVAC technicians have the equipment to identify which parts are causing these sounds and advise you on repairs.

3. Cool Air is Weak

Does your unit’s cool air seem weaker than usual? If you feel like the cooling power of your AC has decreased, it could be time for AC repairs. Weak airflow can come from several different sources, including low refrigerant levels, clogged filters, and dirty evaporator coils. A professional will need to inspect your unit and do a thorough diagnosis before determining what’s wrong. The good news is that weak airflow is much easier to fix than mechanical failures or other issues, so it should be one of the first AC problems you address.

According to the U.S. Energy Information Administration, only 42% of homeowners hire HVAC contractors to maintain their air conditioners. What most of the other homeowners don’t realize is that ACs that are properly maintained last 40% longer. So don’t wait until it’s too late. Hire reputable HVAC contractors whenever you notice any of these signs.
