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. From sudden heating failures to planned equipment upgrades, our experienced technicians can assess your system and recommend a practical solution.

Our team installs, maintains, services, and repairs air conditioning systems for residential and commercial properties. With experience across all makes and models, our trained technicians provide knowledgeable, professional attention to your cooling equipment.

HVAC Installation

A new HVAC system is only as good as the equipment, design, and workmanship behind it. We use quality materials and equipment backed by experience gained through thousands of successful HVAC installations. Our in-house and mobile custom sheet metal capabilities give us additional control over installation fit, workmanship, 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.

  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.
