When your air conditioner stops cooling properly, makes unusual noises, cycles frequently, or won’t turn on, our technicians identify the source of the problem and complete lasting repairs. We service all major residential air conditioning systems and repair components such as compressors, blower motors, capacitors, contactors, coils, and electrical controls to restore dependable cooling.

AC Maintenance

Routine maintenance helps keep your air conditioner operating efficiently while reducing wear on critical components. During a maintenance visit, we inspect the system, clean key components, check refrigerant levels, verify airflow, and identify small issues before they develop into larger repairs.

If your existing air conditioner is no longer operating reliably or repairs are becoming more frequent, we can help you determine if a new system is the better investment. Our technicians recommend properly sized equipment, complete professional installation, and test your new system to verify reliable cooling and efficient performance.

Additional Cooling & Comfort Solutions

In addition to central air conditioning systems, we also install and service ductless mini-splits for homes that require flexible cooling solutions. We also offer indoor air quality services that can improve filtration, humidity control, and overall comfort while your cooling system operates.

Common Air Conditioning Problems We Repair

Air conditioners experience normal wear over time, and even minor issues can reduce comfort, increase energy use, and place additional strain on the system. Identifying and repairing problems early can help restore reliable cooling and prevent more extensive damage.

Our technicians repair a wide range of residential air conditioning problems, including refrigerant leaks, frozen evaporator coils, clogged condensate drains, faulty capacitors and contactors, blower motor failures, compressor issues, thermostat malfunctions, electrical problems, restricted airflow, and systems that won’t turn on or cool properly. After completing the necessary repairs, we test your system to verify it’s operating safely and delivering dependable cooling throughout your home.

Had Harris out to do an assessment on my heater and the technician Chris found a dangerous situation with my heater exchanger that could have slowly put carbon monoxide into my house. I’m grateful that Lee was able to come to the house right away and provide me selections and options. I was able to get a new HVAC system the next day and my family can safely sleep in our home. Everyone from Mathew and Chris M to Lee and the install guys, Louis, Mike and Jhar were amazing and genuinely great people I would have in my home any time.

I was quite satisfied with meeting with Josh, yesterday. While I didn't care for the price, I had to expect things would be that high of a cost. Still, Josh's professional conduct while he was inspecting my tank made it that much easier to say, "yes," and go ahead with the installation request. I am not concerned, at this point, about the job itself. The heater installation, earlier this year was very nicely done and the unit is working great.

The technician first of all was polite, he put his booties on. And I appreciate that because I have hardwood floors original. The technician looked at the situation was able to fix the issue and showed me what can be another possible problem if not addressed.

Requested same day service in the AM and Scott was at the house by 3:00. He was very knowledgeable and professional, making sure that he understood what I wanted regarding the outdoor outlet and the line to it. He worked quickly and left the patio cleaner than when he arrived. I would highly recommend Harris for electrical work.
