On Energy Efficient Air Conditioning Systems

How Old Is Your Home’s Central Air Conditioning?

Did you know that if your central air conditioning unit is over 8 years old, replacing it could cut your cooling costs by 30% or more? Since heating and cooling account for nearly half of the average homeowner’s total energy bill upgrading to an energy efficient AC system can save some big bucks.

Our heating and cooling experts can help you select the best air conditioner for your home taking all the important factors into consideration. We’ll consider the size & number of rooms you wish to cool, as well as the, orientation to the sun, types of windows in the home, quality of insulation, and many other factors that determine your residential load.

Whether you are installing a new system or upgrading an existing heating and cooling system, installing equipment properly is essential to getting the best performance. According to

Energy Star Air Conditioning  “Nearly half of all heating and cooling equipment in U.S. homes never performs to its advertised capacity and efficiency due to incorrect installation.”

We use only the best equipment and our experienced installers make sure that your system is set up properly to ensure maximum performance and the longest lifespan possible for your new system.

Check Out What Some Of Our Air Conditioning Clients Had To Say About Our Work

Always on time and finished ahead of schedule. Very pleased with the entire process. The installers were very considerate of the potential for dust and debris in the house. They covered everything and left things better than when they arrived. I would use Haddon again for any future heating and cooling project. They were great.

Ron F. – Benicia, Ca

They were great. Their proposal came in substantially lower than any other. They were very helpful in redesigning my ductwork to make it much more efficient. My wife was very happy that their crew did a good job of cleaning up after each work day. I recommended them to a friend recently and would definitely recommend them to anyone.

Vincente A. – Dublin, Ca

I would definitely recommend using Haddon Heating and Cooling. The representative was very knowledgeable, did not try to sell me things that I didn’t need, very confident in his work as well as the company that he works for, quoted one price, gave an exact time line of the work to be done, and delivered on time. Hassle free!!!!!
