Thermostats

Thermostats work in conjunction with your heating and cooling systems to help maintain ideal temperatures in the most energy efficient way. Modern electronic thermostats are a huge improvement from earlier and more outdated mechanical styles. Now they have microprocessors which let you program your home’s temperature to match your lifestyle preferences. This allows you to automatically set your temperature to save energy when you are sleeping or away.

Electronic Thermostats

An electronic thermostat works very similarly to an older, manual thermostat. Electronic thermostats have microprocessors that gauge the temperature in the room and compare it to the temperature that you have selected. It then provides a start and stop command to the heating or cooling system in order to maintain the temperature to the one you have set.

Programmable Thermostats

Programmable thermostats work in a similar way to electronic thermostats except that they are much more convenient. After you program the thermostat, you have the capability to customize the system’s operation in order to fit your schedule and lifestyle. The great thing about programmable thermostats is that you only have to program them once until the season or your lifestyle preferences change.

We have radiant floor heat, but added a heat pump. We also needed a new AC. Job took 2 days, since it was such a big job. Very professional & friendly gentleman we had come work. Even had a few new vents put in. The AC has never been cooler...

I had other bids for an A/C and furnace, and Welsh was not the lowest bid, but it was the professionalism and knowledge of Rick (estimator), and the Lennox product that caused me to choose Welsh (for the 2nd time) to install the new system. I was just as impressed...

I would like to again compliment one of your fine employees.  He comes two times a year and is always on time, I told him if he is early come anyway, so now he is a little early, great.  He is very efficient and I think does a good job,...
