Regular maintenance is essential to keep your HVAC system running efficiently, extend its lifespan, and prevent unexpected breakdowns. A.H. Brenner Heating & Cooling offers residential maintenance plans tailored to your home's needs.
If your AC is blowing warm air, running constantly, turning on and off frequently, leaking water, making strange noises, or not turning on at all, it likely needs professional repair. Increased humidity or a spike in your energy bill can also signal a problem.
While you can check for a dirty air filter or adjust thermostat settings, most AC repairs should be handled by a licensed HVAC technician. Improper DIY repairs can cause more damage and even void your warranty.
We recommend scheduling central AC maintenance once per year, ideally in the spring before cooling season begins. Regular tune-ups improve efficiency, extend equipment life, and help catch problems early.
Our maintenance service includes coil cleaning, electrical checks, refrigerant level inspection, thermostat calibration, filter evaluation, condensate drain cleaning, and performance testing. We ensure your system is clean, safe, and operating as it should.
Repair costs vary based on the issue and parts needed. Minor repairs may be relatively inexpensive, while compressor or refrigerant issues can cost more. We provide upfront estimates so you're never surprised.
With regular maintenance, a central AC system can last 12 to 15 years. Neglected systems often wear out sooner, while well-maintained systems may last longer with consistent care.
