Research Lennox Thermostats

Comfort and affordability are number one for A-1 customers. Our technicians recommend programmable thermostats, because it’s estimated that programmable thermostats can cut approximately $180 from your energy bill annually, by reducing heating or cooling when you need it least. Using a programmable thermostat, allows you to adjust the times you turn on heating or air-conditioning according to a pre-set schedule. These settings can be stored and repeat by certain days or hours (six or more temperature settings per day), and can be manually overridden without cancelling a daily or weekly set program. By setting your thermostat back 10-15° for eight hours or more, you can save 5–15% a year on your heating bill. This is a savings of as much as 1% for each degree, if the setback timeframe is at least eight hours long.

A common myth associate with programmable thermostats is the belief that a furnace or air conditioner is forced to work harder than normal to warm a space back up or cool it down to a comfortable temperature after a thermostat has been set back. The fact is when your house drops below or above its normal temperature, it will lose energy to the surrounding environment more slowly. So, the longer your house remains at a lower temperature (or higher temperature if cooling), the more energy you save, because your house has lost less energy than it would have at the higher (or lower) temperature.

There are some exceptions and limitations for the use of programmable thermostats for homes with heat pumps, steam heat, radiant floor heat, or electric resistance heating.

A1 did an excellent job on our furnace and ac replacement after our old unit failed. The new unit also seems to be keeping the temp better regulated and the filter already looks filthy indicating it is doing its job unlike the last setup. I really appreciate everyone that works here and what they do! Update: at my new house I had them assist in putting ducting in the basement as I work towards finishing it. They were prompt and courteous and the work was excellent as always.

Update 2/15/2022: I will continue to rave about this company! Super fast and friendly service! They ALWAYS find the problem and have been so kind and understanding every time! The Owners are wonderful and they do a fantastic job finding wonderful employees to represent their company! I still continue to ONLY use A-1 and recommend them any chance I can get. ............... A-1 has always been Fantastic to do business with. We got our central A/C system installed by them and they even came out to inspect it when things weren't working right. Turns out the issue was user error but they did such an amazing job of being patient with us to explain the issue, educating us on how to better care for our system, and even made sure the entire unit was updated and running smoothly before they left. They are fast in their responses and their 24 hour service is great highly recommend A-1. We won't use anyone else!

I have used this business twice now to repair and tune my furnace. Both experiences have been exceptional. Both of the guys who came at the two different appointments were extremely courteous, very professional, knowledgeable, and timely. For both appointments I have had they were able to come to my home based on what worked best with my schedule and were very flexible. They arrived when they said they were going to and fixed everything that needed to be fixed without taking an entire afternoon. They explained things in a way that made me feel like I understood what was being worked on without feeling like I was being talked down to. I will continue using this company for all of my air conditioning and furnace tuneup and needs in the future!

Aaron did such a super job for us and was so energetic and friendly. He quickly diagnosed the problem, fixed it and assured us that he would return if needed. I am sure he even saved us some money. He called ahead and arrived on time. Can't say enough about this young man and his work ethic.

Got the new furnace seamlessly scheduled for replacement and promptly installed by tech Hunter,new furnace is quieter, more efficient then the old one A-1 installed 29 years ago. Very proffesional service !
