What Are the Most Common AC Problems That Require Repair?

Some of the most common AC issues include refrigerant leaks, frozen coils, electrical failures, and faulty thermostats. Weak airflow, warm air coming from the vents, or frequent cycling can also indicate a problem. Addressing these issues early can prevent bigger, more costly repairs down the road.

How Can I Tell If My AC Needs Repairs or a Full Replacement?

If your AC is over 15 years old and constantly breaking down, it may be more cost-effective to replace it. Frequent repairs, poor cooling performance, and rising energy bills are signs that a new system might be the best option. A professional technician can assess your unit and help you decide on the most practical solution.

Why Does My AC Keep Freezing Up?

An air conditioner can freeze up due to restricted airflow, low refrigerant levels, or a dirty evaporator coil. If the airflow is blocked by a clogged filter or a failing fan, the system can become too cold and ice over. Regular maintenance, including filter changes and coil cleanings, helps prevent this issue.

What Should I Do If My AC Won’t Turn On?

First, check your thermostat settings, circuit breakers, and air filter to rule out simple fixes. If the unit still won’t start, it could be due to a faulty capacitor, compressor failure, or an electrical issue. A professional technician can diagnose the problem and restore your cooling system.

Why Is My AC Running But Not Cooling My Home?

If your AC is running but not providing cold air, it may have a refrigerant leak, dirty coils, or a failing compressor. A clogged air filter or blocked ductwork can also reduce cooling efficiency. Professional servicing can pinpoint the issue and restore proper performance.

Can Running My AC With a Dirty Filter Cause Damage?

Yes, a dirty filter restricts airflow, forcing your AC to work harder and increasing wear on the system. This can lead to overheating, frozen coils, and even compressor failure. Regularly changing your filter improves efficiency and extends the life of your unit.

What Causes Strange Noises Coming From My AC?

Banging, rattling, or screeching noises can indicate loose or broken components, such as a failing fan motor or compressor. Buzzing sounds may signal an electrical issue, while hissing could mean a refrigerant leak. If you hear unusual sounds, it’s best to schedule a repair before the problem worsens.

How Long Does an AC Repair Usually Take?

Most AC repairs can be completed within a few hours, depending on the complexity of the issue. Simple fixes like capacitor replacements or refrigerant refills are usually quick, while major component failures may take longer. A skilled technician can assess the problem and provide an accurate repair timeline.

Josh Butry came out and replaced my outdoor faucet and indoor shut off valve. He was mindful of the house taking care when he was working. He explained my options clearly and without high powered sales pitch to opt for the most expensive fix. He did a great job. I would recommend him.

Christian just stopped by to help out with a tricky clog in our tub that was giving us problems. He arrived early, even better than on-time. He was fast and professional and did a great job of explaining what he was doing and what I can do to help prevent the problem from returning. The price was great and after having a pretty negative experience with Roto Rooter recently Roy's has definitely won my business today. When I inevitably have another plumbing issue I can't fix someday I'll be calling them again for sure!

After having been out of town for two weeks, my husband and I came home Friday night to find a cold house waiting for us as the heating system wouldn’t turn on. I frantically searched online Saturday morning to look for a heating and cooling company that would offer 24/7 emergency HVAC services and found Roy’s. They sent over their technician quickly, who diagnosed the problem, offered a couple of solutions for us to choose from, and installed a new system on Monday! We had a great experience with Roy’s and appreciate their professionalism, swift problem-solving practice, and transparency in pricing. Thank you so much!
