Mason, OH HVAC Repair

If your heat or AC isn’t working the way it should, you’re probably already feeling it—rooms that won’t warm up or cool down, uneven temps, strange sounds, or barely any airflow. These kinds of issues don’t sort themselves out. Call us for HVAC repairs in Mason when you notice:

• Sudden increase in energy bills
• Uneven temperatures from room to room
• Weak airflow or barely any air coming from vents
• Strange sounds like banging, rattling, or buzzing
• System short-cycling or constantly turning on and off
• Water leaks or pooling near the indoor unit
• Bad smells coming from vents or the unit
• Thermostat not responding or showing inaccurate readings

If your system has completely stopped—or your home is getting dangerously hot or cold—you may need emergency HVAC repair, which we can also help with. Contact Hill-Air Heating & Air Conditioning today for HVAC repair in Mason, OH, and get your system back up and running.

Homes in Mason don’t all heat and cool the same way—some use gas furnaces, others have heat pumps, and plenty rely on older boilers or newer ductless setups. Whatever your system looks like, one thing’s certain: when it breaks, you need someone who knows how to fix it. At Hill-Air Heating & Air Conditioning, we’ve been repairing heating and cooling systems in all kinds of homes for over three decades. No matter what you use to stay comfortable, we can get it working again.

Furnace Repair

From faulty ignitors and cracked heat exchangers to bad blower motors and dirty flame sensors, most furnace repairs come down to a few key parts wearing out or failing. We’ll inspect the system, identify what’s gone wrong, and get your heat back on safely and quickly. Our furnace repair service is available for gas, electric, and propane models.

Air Conditioning Repair

AC units in Mason take a beating during the summer. Common calls for air conditioning repair include refrigerant leaks, frozen coils, failed capacitors, and clogged drains. We’ll diagnose the issue, check for airflow problems, and get your home cooled down without delay.

Heat Pump Repair

Heat pumps are efficient, but when they fail, you lose both heating and cooling. We handle all types of heat pump repair, from reversing valve issues to fan problems and low refrigerant levels. If your system is stuck in one mode or not keeping up, we’ll get it sorted out quickly.

Ductless Mini Split Repair

Mini splits are great until something’s off, like zones not responding, indoor units dripping, or unusual error codes. Our ductless mini split repair service covers indoor and outdoor units, electrical components, fan issues, and more. We get each zone working the way it should.

Boiler Repair

Older homes in Mason often use boilers for radiant heat. If yours isn’t producing heat, is leaking, or making banging sounds, we can help. Boiler repair typically involves checking the pressure, valves, circulation pump, or thermostat controls—and we’re equipped to handle it all.

We also repair air handlers, which are the parts of your HVAC system that move air through your home. If your system turns on but you’re not feeling much airflow—or if it’s making unusual noises—the air handler could be the problem.

If you’ve installed indoor air quality equipment—great move. These systems make a big difference in how your home feels and what you breathe every day. But just like your heating and cooling system, they need occasional attention to keep doing their job. If something isn’t working quite right, Hill-Air offers fast, reliable indoor air quality repair services in Mason and the surrounding areas.

Air Purifier Repair

Air purifiers can stop working if the filter is clogged, the unit loses power, or internal sensors fail. Our air purifier repair service includes a full inspection of the system, filter replacement if needed, and electrical diagnostics to make sure it’s cleaning your air like it should.

Dehumidifier Repair

If your dehumidifier isn’t pulling moisture from the air, it might have a clogged drain line, sensor failure, or compressor issue. With our dehumidifier repair, we troubleshoot the entire system and get it back to keeping your home dry and comfortable.

Humidifier Repair

Low humidity in the winter is uncomfortable, but so is a humidifier that stops working. Whether it’s a stuck valve, faulty solenoid, or dirty water panel, we offer complete humidifier repair to get moisture levels balanced again.

Media Air Cleaner Repair

Media air cleaners are low maintenance, but they still need attention once in a while. If your system isn’t improving air quality like it used to, we’ll check for airflow issues, replace the filter, and handle any mechanical problems during your media air cleaner repair.

Thermostat Repair

A thermostat that’s reading the wrong temperature or won’t respond can throw your whole system off. We provide thermostat repair for smart, programmable, and manual models—fixing wiring, sensor issues, and more to keep everything running smoothly.

UV Air Cleaner Repair

UV air cleaners rely on working bulbs and solid electrical connections. If yours has stopped running or isn’t making a difference anymore, our UV air cleaner repair includes checking the ballast, replacing the bulb, and testing the entire system.
