Heating Services

Cold temperatures can quickly reveal problems with your heating system. We install, repair, service, and maintain heating equipment with a focus on reliable operation and quality materials. Whether you’re dealing with an unexpected failure or planning an equipment upgrade, our experienced technicians can identify the problem and provide a practical path forward.

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. 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. Thousands of completed installations have given Furnace Doctors extensive experience working with high-quality HVAC equipment and materials. 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. Our professional HVAC maintenance and repair services are designed to help heating and cooling equipment continue operating as intended. 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

Furnace Doctors has stayed busy for decades without depending on costly television or radio advertising. Quality workmanship and customer referrals have built the reputation we have today. Because we keep our work in-house instead of subcontracting it, we can oversee quality from start to finish. Our extensively trained, factory-certified technicians are supported by an in-house fabrication shop, mobile sheet metal capabilities, and a licensed electrician for more demanding HVAC projects. Some team members have been with Furnace Doctors for decades, giving customers access to extensive knowledge developed through real-world HVAC experience.

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.
