Older heating and cooling systems may run for years without major mechanical problems, but even so, they use so much energy that they become very expensive to operate. Equipment of fifteen years ago, like the automobiles of that era, is much less efficient than that of today.

In fact, most older furnaces are vastly less efficient than the models that Lennox now offers. For example, a typical gas furnace more than ten years old may operate at only half the efficiency of some new Lennox high-efficiency models.

Older heat pumps and air conditioners have the same drawback. Even units only five years old may operate at very low efficiencies, compared to today's Lennox models. In addition to costing you more to operate because of its low efficiency, every day you operate your old heating and cooling equipment, you run more of a risk of breakdown.

So whether you're faced with a breakdown or just know that your heating and cooling equipment is getting old, now is the time to replace it with a Lennox high-efficiency system.

Diagnosed the problem quickly and fixed it right away. We had burned up contacts in our ac unit and he also did a great tune up. Derek was very professional and was a pleasure to have around for the short time he was here.

Customer Testimonials

Steven and Rob made the installation experience very pleasant and went above expectations to ensure the installation went well. The installers were very good about answering any questions and ensured that everything was installed correctly. The wrong furnace model was ordered and Steven and Rob went and picked up the correct model. They were very apologetic about the mix-up. There was also an error with the original order in that a new line set was not part of the original estimate. The company was very good about making everything right with the project. I would highly recommend this company for your heating and cooling needs.


What a relief to have real professionals who don't just hand you a quote, but explain what things mean and why. They took the time to make sure I knew not only how everything worked, but why it works that way. Courteous, polite, organized AND efficient...and that's saying something because our situation was a mess due to fault of the previous company. You can't go wrong with Littleton!


After having several companies come quote me for a new A/C and furnace, I settled on Littleton Heating and Air Conditioning based on their ability to explain to me what my house needed. It's hard to find companies that won't take advantage of someone with no knowledge of their industry and they answered every question with courtesy and took the time to explain it to me. When they were in my house and after they finished they were very courteous, clean and helpful. I would recommend them to everyone I know.


Dan was very informative and helpful in servicing my furnace. He encouraged me to ask questions and I learned some easy but important maintenance tips to ensure my heating and cooling systems will be efficient and reliable!
