AC Installation & Replacement

When buying a new AC, proper sizing and installation are essential for performance and efficiency. If the system is too small or too large, it will not sufficiently cool your home and the life of the equipment may be shortened. We will explain your options and help you select a unit with the right capacity for the size of your home.

Heater Replacement & Installation

We offer installation of high-quality heating equipment, including furnaces and heat pumps from the best known and most respected brands in the industry. When the time comes for a new heater, we can explain your options to help you select the right equipment for your home. We offer free estimates on all installation and replacement services.

Factors that determine whether repair or replacement is the right choice include:

  • The age of the equipment
  • The condition of your current system
  • Whether your equipment has broken down in the past

All Fairfax heater and AC services are performed by our highly trained and experienced NATE certified technicians. Our technicians are professional, polite, arrive on time, and respect your home. We use floor mats, shoe covers, and leave your home as clean as we found it. After the installation is complete, we will provide a full explanation of how everything works on your new system.
