Frequently Asked Questions


You have a problem when your AC freezes up, either inside or at the outdoor unit. When your AC is frozen, you could subject your system to serious damage if it isn't addressed promptly.

Many homeowners have difficulty deciding whether to keep pouring money into their aging air conditioning system for costly repairs or upgrade to a new, more efficient AC.

First things first, you shouldn't attempt to fix your noisy air conditioner on your own! Unless you have professional knowledge of HVAC electrical system layouts and the proper meters to test all the working components of your AC, you are putting yourself and your air conditioner at significant risk for harm.

A dual-zone air conditioning system is a network of thermostats and duct dampers that regulate the amount of cooled air each zone (one or more rooms) receives throughout the day. Zoning technology allows homeowners to cool only the occupied areas of living space at any given time or to set different temperatures in different areas of the home.

Saving money on your monthly electric bills in the summer is important—so what is the best thermostat setting during the hottest season of the year? We recommend keeping your thermostat set to 72 degrees (at the lowest) with the fan set to AUTO rather than ON.

Money is always a big concern for homeowners all over the country—but how can you lower your electric bill this summer without sacrificing comfort? You can do a few things to lower your energy usage, from raising the temperature to closing the curtains.

HCFC-22, commonly called R-22, has been a common refrigerant used in residential heat pumps and air conditioners for more than 40 years. But releases of R-22, such as those from leaks, contribute to ozone depletion, and the making of R-22 results in a byproduct that contributes to global warming. The EPA is now phasing out this refrigerant. By January 2020, chemical manufacturers will no longer be able to produce R-22.


Many homeowners are concerned about their growing utility bills with home heating fuel prices rising! Find out what you can do to lower your costs!

Since boilers have very few moving parts, they tend to be incredibly durable and reliable throughout their life. However, even the most dependable appliances will eventually reach their end.

Gas boilers can be more affordable to operate, but there are also differences in utility line requirements and fuel storage (natural gas has no onsite storage needs).

We have a few tips on what you should do when the heat goes out, including layering your clothes, calling the power company, etc.

A hydronic system, also called radiant heating, circulates hot water or another heated liquid through plastic piping installed beneath the floors, baseboards, or radiators. Hydronic heating allows you to control the temperature in specific zones throughout your home precisely.

Heat Pumps

A heat pump works by transferring heat energy from one source to another. In the winter, when your heat pump acts as a heating system, it extracts heat energy from the outside air (even in near-freezing temperatures) and transfers it into the air in your home. When summertime rolls around, it's as easy as flipping a switch to change your heat pump to cool mode.

Heat pumps are one of the most energy-efficient HVAC systems available because they don't burn fuel to provide heat. In addition to their high efficiency, they can operate as both a heating and cooling system, thus reducing the number of systems that require maintenance, repairs, and replacements.
