Our Services

A/C installation

We offer high quality installation of residential and commercial air conditioning with the use of professional equipment and fine materials, at a lower cost.

Maintenance and repair

We provide a full range of repairing and maintenance of air conditioning systems, ventilation systems, light industrial and industrial split systems.

Pre-season preparation

Air conditioning systems are regulated appliances, requiring expert maintenance to properly function at the best rate of energy consumption.

Annual inspections

An annual inspection allows a technician to identify dirty coils and burned out contactors before they cause long term damage to your system.


If your home heating system should break down or stop working properly, it is important to have a company you can trust to perform the heating repair services you need quickly, reliably and affordably.


For larger homes, a whole house fan provides excellent ventilation to achieve lower indoor temperatures. For homes with ducts, an alternative approach uses those ducts to supply ventilation air throughout the home.

Techs are friendly and know what they are doing. It's rare these days to find a company that is genuinely down to earth and willing to work with you. Best customer service attitude I have ever encountered! Will for sure use Falcon for all my yearly HVAC needs.

Efrain kept in constant contact with us as he planned and scheduled the work. Carla was amazing to work with for coordinating technician visits.
There was no issue getting them back on site to finish some work after the drywallers were complete.
Everyone was incredibly kind and respectful of our home, not to mention showed up when they said they would!
I'd highly recommend FalconHVAC for anyone looking for a reliable, straight shooting HVAC contractor/technician - and this is coming from someone who designs HVAC systems every day. The final system looks fantastic and works perfectly.
