Why Consider a Thermostat Installation with a New HVAC System Installation?

Thermostats are one of the most important parts of any HVAC system. The thermostat is the control center of your heater and air conditioner, responsible for determining when they activate and for how long. Despite being so vital, however, thermostats are among the most neglected when it comes to maintenance and replacement. Many homeowners have thermostats that are significantly older than the heating systems they operate, and for no other reason than they aren’t considered a problem as long as they’re working properly. Actually, there are a number of very good reasons to have a new thermostat installed along with a new HVAC installation. Let’s examine some of those reasons now.


If you opened up a thermostat from 30 or 40 years ago, you’d find that it was more or less entirely mechanical. Most thermostats in those days used temperature sensors that were extremely inaccurate, despite being the best available at the time. Ampules filled with mercury and heat-sensitive coils did the job decently, but they had huge dead zones where they were not sensitive enough to activate the heater or air conditioner when needed. Later electronic thermostats had a huge advantage in terms of sensitivity and energy efficiency, which is why you’ll find them in most homes today. However, a lot of homeowners seem content to use a thermostat that’s over a decade old, despite much more accurate models being available.

Modern thermostats are leaps and bounds better than older electronic thermostats, just as those thermostats were better than the previous generation of mechanical thermostats. New sensor technology gives more modern thermostats even greater control over a home’s climate, making your living space more comfortable.

Some thermostats are even becoming adaptive, able to learn and anticipate your heating and cooling needs. With these systems, you barely have to touch the thermostat to achieve a comfortable home climate. The options that these new thermostats present make them worth using, both because they’ll save you money and make your home more comfortable.
