Indoor Air Quality Solutions

Your home’s indoor air quality can impact both your comfort and your health. Hancock Refrigeration offers air purifiers, air ventilators, air cleaners, and home humidifiers to help you address a variety of air quality concerns. We can assess your home and help you decide what you need so you get the perfect fit for your situation.

Ductless Air Conditioning

Ducted air conditioners are prone to air loss and inefficiency. With a ductless system, you can customize your comfort at every individual unit in the home. This solution eliminates the ductwork for affordable comfort. Reach out to our team to learn more about whether a ductless installation is right for your needs.

Routine HVAC Maintenance

You should schedule maintenance services for your heater and air conditioner once a year. Our maintenance plans are designed to make it easy to stay on top of this regular maintenance appointment. A system that’s well-maintained will have fewer repair needs, greater energy efficiency, and a longer lifespan. Make your appointment now!
