What are the most common AC problems that require repair?

Common AC issues include warm air, weak airflow, refrigerant leaks, frozen coils, clogged condensate drains, thermostat malfunctions, capacitor or contactor failures, fan motor problems, and electrical issues that prevent the system from running properly.

How can I tell if my AC needs repairs or a full replacement?

Repairs are often suitable for newer systems with a specific fix. Replacement may be a better option if the unit is older, breaks down frequently, struggles to cool consistently, or needs a major component replacement.

Why does my AC keep freezing up?

Freezing is usually caused by restricted airflow (dirty filter, blocked vents, blower issues) or low refrigerant. Turning the unit off to thaw and scheduling service is recommended to prevent further damage.

What should I do if my AC won’t turn on?

Check the thermostat settings, replace batteries if applicable, confirm the circuit breaker hasn’t tripped, and verify the system’s disconnect is on. If it still won’t start, a technician can diagnose electrical or component-related issues safely.

Why is my AC running but not cooling my home?

This may be caused by low refrigerant, dirty coils, restricted airflow, a failing compressor, or thermostat issues. A professional diagnostic can identify the cause and restore proper cooling.

Can running my AC with a dirty filter cause damage?

Yes. Dirty filters restrict airflow, reduce efficiency, and can contribute to coil icing or overheating. Replacing filters regularly helps protect your system and reduce the risk of repairs.

What causes strange noises coming from my AC?

Unusual noises can indicate loose components, fan or motor issues, debris in the unit, or electrical problems. It’s best to have the system inspected to avoid more extensive damage.

How long does an AC repair usually take?

Many AC repairs can be completed the same day, depending on the issue and part availability. After diagnosing the problem, your technician can provide a clearer timeframe.

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.

Everything about my experience with Roy’s is positive. The original estimator who came out, and the three man crew who did the job All highly professional. Did their work impeccably, as promised, no hidden charges or add-ons like with so many contractors, they cleaned up after they were done. Top-notch. Angelo, Joel and Kyle were the contractors and if I need more work at my house, I’m going to request that specific crew. A+.

Fiushed my water heater. Done a great job. Very polite. Had to call Roy's. My basement water coming up the drain. Josh B came out. Josh and Eric B.jetted my clean out pipe. Found my sewer had dropped six inches. Which means had to dig up and get sewer rerouted. Josh did an excellent job laying out what needed to be done. Plus had to relocate my sump pump drain. Got everything together. Next day the whole team came out and got started. One crew in basement. Other crew outside. What a BIG job. They all worked together. Everyone of the guys were great. If I could give them 10 stars I would. You want a job done the right way. Call Roy's plumbing.

Josh B came out to my house to provide an estimate for a few projects. Off the bat, he was professional and explained his background which instilled my trust in his expertise. He was patient when I asked a bunch of questions and gave some advice on items that we didn’t necessarily need to hire him for. The icing on the cake was that he brought in my recycling bin from the street! My husband and I will be using Roy’s for our garage project because of how great Josh was. Highly recommend!
