HVAC Installations and Replacements

If it's time for a new HVAC system, have us perform an in-home assessment. We'll help you compare your options, whether you're looking for a traditional single-stage unit, a variable-speed system, or a ductless mini-split. New heating and cooling technology can increase comfort and lower energy bills by 15% or more.

HVAC Diagnostics and Repairs

If your heating or cooling system is not functioning as expected, contact Wintri for responsive diagnostic services. We'll pinpoint the problem and explain the best way to correct the issue depending on the age of your AC system. Plus, in-stock replacement parts help us complete repairs faster while minimizing inconvenient delays.

Heating and Cooling Maintenance

For more reliable heating and cooling, have your air conditioner or heater serviced once per year at the beginning of the season. Our service technicians will evaluate every part of your system, from the capacitors and electrical connections to the heat exchanger and controls. When properly maintained, your heating and air system will last longer and perform more reliably and efficiently.

Indoor Air Quality Services

A whole-house filtration system or ventilator can take your comfort to the next level while reducing allergy symptoms and controlling excessive dust. Air cleaners remove up to 99% of airborne pollutants, including pollen, smoke, and germs. Professional duct cleaning services remove contaminants that build up in your ductwork to help improve your home’s air quality even further.
