HVAC 101:

A Quick Guide

Repair or Replace?

Replace your existing system when repairs cost 30% of a new purchase or when utility bills have increased 50% as a result of your older, less efficient system.

Best Thermostat?

Look for a programmable thermostat for accurate, reliable, energy-saving performance. Our Wi-Fi Communicating Control lets you easily program your system from wherever you are. 

How do I Improve Indoor Air Quality?

Indoor air can be 5 to 100 times more polluted than outdoor air. Adding a humidifier, UV light and air purifying technology can improve your indoor air quality (IAQ), removing molds, bacteria and viruses from the air you breathe.

How Much Can I Save?

Air conditioning and heating equipment consumer about 44% of your home's energy bill. An ENERGY STAR qualified system is 60% more efficient than 10-year-old equipment

How do I choose a Contractor?

Seek out a contractor who is associated with a recognized brand. If they are backed by the product and training resources of a major manufacturer, you can feel confident you're getting a system that meets your needs.
