About Us

Furnace Doctors was founded in 1986 as a family-owned and operated business, building on an HVAC tradition that began decades earlier. The family entered the industry in 1953, and that legacy continues today through second-generation ownership and active third-generation involvement. Thousands of completed installations and years of customer referrals have helped us build a business grounded in lasting relationships. From heating and air conditioning service to installation, repair, and maintenance, we’re your one-stop heating and air conditioning shop. We’ve always focused on what matters most: expert service, dependable equipment, skilled workmanship, and results designed for long-term performance. Learn More

Heating Services

Cold weather puts your heating equipment to the test. We install, repair, service, and maintain heating equipment with a focus on reliable operation and quality materials. From sudden heating failures to planned equipment upgrades, our experienced technicians can assess your system and recommend a practical solution.

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. We service all makes and models, applying extensive technician training and real-world experience to every project.

HVAC Installation

Quality equipment matters, but proper design and skilled workmanship are equally important to a successful HVAC installation. Furnace Doctors uses high-quality materials and equipment and has completed thousands of successful installations. With custom sheet metal fabrication available in-house and in the field, we can approach installations with greater control over fit, quality, and performance.

HVAC Maintenance & Repair

Ignoring a seemingly small heating or cooling problem can lead to a more disruptive issue later. Our professional HVAC maintenance and repair services are designed to help heating and cooling equipment continue operating as intended. HVAC trouble doesn’t always follow a convenient schedule, which is why our on-call service department provides after-hours assistance.

Why Choose Us

There’s a reason Furnace Doctors has remained busy for decades without relying on expensive television or radio advertising. Our reputation has been built through quality work and customers recommending us 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. With experienced staff members who have spent decades with our company, customers benefit from knowledge that only comes through years of hands-on HVAC work.

  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.
