Your heating equipment has to perform reliably when colder weather arrives. Furnace Doctors handles heating installation, maintenance, service, and repair with dependable performance as the priority. Whether your heater has unexpectedly failed or you’re considering an upgrade, our technicians can diagnose your needs and explain the next steps.

Air Conditioning Services

When indoor temperatures start climbing, Furnace Doctors can help restore reliable cooling. We service, repair, maintain, and install air conditioning equipment for homes and businesses. Our technicians work with all makes and models, bringing extensive training and proven experience to each job so your system receives knowledgeable, professional attention.

HVAC Installation

The performance of a new HVAC system depends heavily on its equipment, design, and installation quality. Furnace Doctors uses high-quality materials and equipment and has completed thousands of successful installations. Because we can fabricate custom sheet metal both in-house and in the field, our team can better manage the fit and quality of an installation.

HVAC Maintenance & Repair

Minor HVAC problems can turn into much bigger headaches when left unresolved. We provide experienced repairs and ongoing maintenance to help keep HVAC equipment performing properly. Our on-call service department also offers after-hours service, giving customers access to experienced help when HVAC trouble doesn’t happen during ordinary business hours.

Why Choose Us

There’s a reason Furnace Doctors has remained busy for decades without relying on expensive television or radio advertising. Our reputation comes from doing quality work that customers feel confident recommending to others. Because we keep our work in-house instead of subcontracting it, we can oversee quality from start to finish. Factory-trained technicians, custom sheet metal fabrication, mobile fabrication capabilities, and an on-staff licensed electrician give us the resources to tackle complex work properly. Some team members have been with Furnace Doctors for decades, giving customers access to extensive knowledge developed through real-world HVAC experience.

  I had a great experience with Furnace Doctor.
Rhett arrived on time, quickly diagnosed the issue, added refrigerant, and had my AC running properly again in no time. He was professional, efficient, and explained what he was doing without trying to upsell unnecessary work. The whole process was smooth and stress-free.

  Had a great experience with Furnace Doctors. Technician JJ was extremely knowledgeable and took a very systematic approach to troubleshooting and diagnosing our HVAC issue. He carefully checked all components, including temperatures, capacitor functioning, and coolant levels, and thoroughly tested the system after the repair to confirm everything was working properly. JJ explained the process clearly and was professional throughout the visit. Really appreciated the attention to detail and confidence in the work performed. Highly recommend! The poor ratings online did not reflect the experience I had.
