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.

Today i had an appointment with Roy's to troubleshoot my AC unit. Manny was the repair technician that arrived right on time and was very friendly and he was able to diagnose the issue with the AC unit right away and he explained everything to me and what repair needed to be made to get the AC running efficiently again. He was very professional and very detailed in his repair and the price was fair for what needed to be replaced and when Manny was finished with the repair he explained what he did and asked me if I had any questions or concerns. While he was here he also set an appointment for a furnace check up in the fall. I appreciate Manny's professionalism and attention to detail with my appointment today thank you so much ☺️

I woke up to a broken air conditioner and immediately called Roy’s. They were able to come out same day. The service technician Ryan Bigelow was very polite, friendly and helpful. He offered me options to replace the parts in my very old unit, but I’m going to opt to purchase a new one since the unit is so outdated. Ryan was able to schedule someone to come out same day to price a new unit for me. I’m very pleased with the efficient turnaround and look forward to using Roy’s to install my new unit.

Josh Butry was our tech and I highly recommend him. We’ve had other company techs here for quotes but they do not compare to Josh’s professionalism and knowledge. He is very thorough, explains everything and quoted reasonable pricing and service dates. Roy’s also offer a yearly membership for discounted services.

I had two separate appointments, one to install a GFCI outlet and a second for A/C maintenance. Nick installed the outlet, did a great job. Dominik completed a/c maintenance, also did a great job! Both were friendly, explained every step of the process, explained pricing and any recommendations. Friendly, on time and a reasonable price for the work completed. Highly recommend and will be calling Roy’s for future needs.

Tim our plumber showed on time and explained what he was going to do to solve our problem. His solution was 10 times better than mine. He told us the price once I signed off, he immediately started work and finished in the time period he told us. Everything was cleaned up.

Roy's accommodated my request for a later time window and I was notified when the technician was on the way. Josh B arrived and attacked the problem from every possible angle. He narrowed down the issue and offered multiple solutions. We don't know which we will go ahead with, but Josh provided us with what we need to make an informed decision. Recommended!
