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.

Loved this company, very professional, friendly, and always got back with me quickly. Out of the 4 other company’s I called they were able to do what the others refused to do. They did it fast, the installation looks great, and looks sooo much better. Would definitely recommend this company.

West Milton, OH
Brad and his team were amazing! They went out of their way to get our furnace installed fast and were very thorough! Customer service and communication was great!!! Thank you!!!

Piqua, OH
Our AC unit broke down on a Friday before Labor Day. I called Roberts Brothers that Friday and they were out there the same day. They ordered the unit we agreed on and had it installed the next business day. In the meantime, they provided a temporary AC unit we used inside the home. This was a blessing to us! The crew was nice and kept us in the loop as the installation was going on.

Troy, OH
We had an A/C unit that was failing on the hottest day of the year and Brad was able to find a replacement and Roberts Brothers techs got it installed the next morning.

Troy, OH
Always great service, communication and response time. A quality, reliable company that we trust with all of our heating and cooling needs!

Piqua, OH
I was unable to get ahold of the service I had previously used. Roberts Brothers were recommended by two different people. They were prompt and solved my problem quickly. I will most definitely call them 1st in the future.
