THE VARITECH DIFFERENCE
Why Choose Varitech Commercial Services For HVAC?
When your rooftop unit, exhaust hood, or make up air system goes down, comfort and code compliance are both on the line in a Tucson summer. Here’s what sets Varitech Commercial Services apart for HVAC service.
Highly-Skilled Technicians
Our Tucson based HVAC specialists receive ongoing training and certification from leading manufacturers, so the technician who shows up already knows your rooftop unit or exhaust system.
We Stock the Most Commonly Used Parts
Our Tucson based technicians stock the most frequently used genuine manufacturer parts on their service vehicles. No generic substitutes, only parts that meet factory specifications.
90-Day Guarantee
Our technicians arrive in GPS equipped vans with the tools and parts for same day service across Tucson and Southern Arizona. We back their work with the Varitech guarantee (90 days parts and labor).
Planned Maintenance Programs
Rooftop HVAC units run nearly year round in a market where summer temperatures routinely top 100 degrees, and that extra runtime wears components down faster than in a milder climate. Our PM programs include burner and heat exchanger inspection, thermostat and control calibration, belt and filter checks, refrigerant and gas pressure testing, and coil cleaning to catch that wear early.
All Fuel Types & Configurations
Gas, electric, and dual fuel, we service every configuration, from rooftop package units to split systems, across Tucson’s commercial buildings. Our technicians are trained on gas fired and electric heating systems across all major HVAC brands.
