Schedule an AC diagnostic service call

A proper repair starts with a proper diagnosis. When you call us for air conditioning repair, our technician will inspect your system, check the equipment, and look for the source of the problem.

Your AC issue may involve a failed capacitor, low refrigerant, a dirty coil, a clogged condensate drain, a bad fan motor, a thermostat issue, electrical trouble, or another part of the system. Once we identify the problem, we will explain what we found and talk through your repair options.

Our goal is simple: get your cooling system working again and help you stay comfortable in your home. We also do AC repair in Covington, Fletcher, Piqua, Tipp City, Troy and West Milton.

Common air conditioning problems we repair

AC blowing warm air

If your air conditioner is running but the air from your vents is not cool, the problem could be caused by low refrigerant, a dirty outdoor coil, poor airflow, a failing compressor, or an issue with the thermostat. Before calling for service, make sure the thermostat is set to cool and the temperature setting is lower than the current indoor temperature. If the system still will not cool properly, Roberts Brothers Comfort can inspect the unit and find the cause.

Poor airflow

Weak airflow can make your home feel warm even when the air conditioner is running. Common causes include a dirty air filter, blocked vents, ductwork problems, a struggling blower motor, or a dirty indoor coil. Try replacing the air filter and checking that your supply vents are open. If airflow is still weak, the system should be checked by an HVAC technician.

AC will not turn on

If your air conditioner will not turn on at all, check your thermostat, circuit breaker, and air filter first. A tripped breaker, loose thermostat setting, clogged filter, or full condensate drain pan can sometimes shut the system down. If the system still will not start, do not keep resetting the breaker. There may be an electrical issue or failed component that needs professional service.

AC short cycling

Short cycling means your air conditioner turns on and off too often. This can make your home uncomfortable, raise energy costs, and put extra strain on the equipment. Short cycling may be caused by a dirty filter, low refrigerant, an oversized system, thermostat problems, or a failing electrical part. Roberts Brothers Comfort can inspect the system and recommend the right repair.

Frozen AC coil

Ice on your air conditioner is not normal. A frozen coil can be caused by restricted airflow, a dirty filter, low refrigerant, a dirty evaporator coil, or a blower problem. If you see ice on the system, turn the cooling off and let the fan run. Then call for service. Running the system while it is frozen can lead to more damage.

Water leaking around the AC unit

Air conditioners remove moisture from indoor air. That water should drain safely through the condensate drain system. If the drain line clogs or the pan overflows, water may leak around the indoor unit. This can lead to water damage, humidity problems, and system shutdowns. We can clear drain issues, inspect the condensate system, and make sure your AC is draining correctly

Strange noises from the air conditioner

Grinding, buzzing, rattling, squealing, or banging sounds should not be ignored. Noises can point to loose parts, motor problems, electrical issues, debris in the outdoor unit, or a failing compressor. Turning the system off and calling for service can help prevent a small repair from becoming a larger one.

Our furnace went out during a very cold snap. A company I was using could not come for 3 days. Roberts came same day. We ended up having to replace but they did a great job start to finish.

Katrin Holmes

Tipp City, OH

Sean from Robert’s Brothers Comfort was absolutely wonderful to work with. After having a bad experience with another company that came out, he was truly a breath of fresh air. He was incredibly kind, courteous, and professional from start to finish. He took the time to thoroughly explain everything to me and even showed me pictures of exactly where the issue was coming from, which I really appreciated. He was patient, answered my questions, and gave me time to take notes so I could fully understand what was going on. What also stood out was how respectful he was of our home – he made sure doors were shut and lights were turned off without me having to worry about it. That level of thoughtfulness says a lot. Sean was very knowledgeable, honest, and genuinely pleasant to have in our home. I would absolutely recommend him and the company to anyone needing HVAC service.
