The way we see it, cool breezes are best left outside in winter. That’s why our innovative gas- and oil-fired boilers are designed to spread nothing more than consistent warmth—not to mention peace and quiet—through your radiant system.

In-Floor Heating

Dale’s Service & Refrigeration provides quality customer service for In-floor radiant heating, Air cleaner replacements, and Commercial Refrigeration repairs and installation.


Think of your furnace as the heart of your home. In the winter, it’s essential to radiating warmth. During the summer, it plays a vital role in moving refreshing, conditioned air from your cooling system. And all year long, your furnace could provide constant air circulation to keep you more comfortable.

Air Conditioning

What kind of condition is your air conditioning in? Noisy? Uneven? If your old system just doesn’t make you feel the way you used to, we can help. Refreshingly energy efficient, quiet and durable, therefore, our air conditioning systems are meticulously designed to keep you cool.


If you’ve been holding your breath for cleaner air, the wait is over. Our state-of-the-art air purifier systems trap and kill bacteria, viruses, mold spores, allergens and other pollutants in the conditioned air—and keep them out of the air your family breathes.


No one likes too much humidity. But too little can be just as irritating, especially in winter. When humidity drops too low, you might notice sore throats, chapped lips, itchy skin and sinus problems. To help, we offer a variety of products designed to keep your home at a comfortable humidity—and everyone in it feeling great.

Home stand-by generators

For uninterrupted power supply and for the comfort of your home, home standby generators are suitable. As soon as there is a power supply outage they are turned on automatically within seconds.

Air to air exchangers

If your home has ductwork, forced-air or water-to-air heat pump models can supply treated air to heat and cool your home all year long.

Geo-thermals heat pumps

Forget oil or gas, geothermal systems tap into the relatively consistent temperatures of your yard, pond or well and runs on electricity but uses the earth’s thermal energy to so you can enjoy higher energy efficiency inside—no matter how extreme the weather gets outside.
