About Us

The family entered the industry in 1953, and that legacy continues today through second-generation ownership and active third-generation involvement. Our company has completed thousands of successful installations while growing primarily through word of mouth and trusted customer relationships. With heating and air conditioning installation, maintenance, service, and repairs available from one team, we’re equipped to handle your ongoing HVAC needs. 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

Your heating equipment has to perform reliably when colder weather arrives. We install, repair, service, and maintain heating equipment with a focus on reliable operation and quality materials. 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

As indoor temperatures rise, our technicians can help restore the dependable cooling your property needs. 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

The performance of a new HVAC system depends heavily on its equipment, design, and installation quality. We use quality materials and equipment backed by experience gained through thousands of successful HVAC 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

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. With an on-call department offering after-hours service, Furnace Doctors can provide experienced assistance when problems occur outside normal business hours.

Our reputation has been built through quality work and customers recommending us to others. No phase of our work is subcontracted, allowing our team to maintain control over quality throughout the job. 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.

Thank you!

  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.
