HVAC Basics

To keep your home cool, your AC system refrigerates, circulates and dehumidifies indoor air. Choosing an energy-efficient cooling unit is key to improving performance and lowering energy costs.

How your central air conditioning system works.


How does my furnace work?

The furnace keeps your home warm during cool months and is the core of your heating equipment. When it is time to replace your furnace, you’ll be replacing all of the “working parts” of your heating system. As with your air conditioner, it is important to consider a range of brands, models, and efficiencies to ensure that your system is cost effective and high performing.


What role does my thermostat play in the heating & cooling process?

Your thermostat controls the temperature of the air, whether you are heating or cooling your home. It measures the room temperature and cues the HVAC system to turn on and off to maintain your designated comfort level. Your Clockwork team will recommend optimal placement for your thermostat so that it can accurately track and maintain your heating and cooling levels.

Consider a programmable thermostat, which can be set to change the temperature of your home when you sleep, awake, go to work or take a vacation. You will save money on your energy bill if your system runs less when you are not home, or when you aren’t awake. Clockwork technicians can recommend an affordable, programmable thermostat that is user-friendly and suitable for your system.
