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.

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.

  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.
