Replacing Your HVAC System

When it's time to replace your system, there are three factors to consider when choosing a replacement system.

Efficiency     Refrigerants     Comfort

When is it time to replace my system?

The decision to replace existing equipment is based on several considerations. The most common is that your present system is broken and there is no economic justification for trying to repair it. Today's higher efficiency equipment with innovative comfort features often convince owners to replace older unreliable systems that have not yet completely failed.


Our constant recommendation to our customers is that the best time to replace your system is when YOU are planning on it, not when the system finally fails and you are desperate. We are happy to give free in-home evaluations when your system is approaching the end of its useful life, 15 to 20 years for heat pumps and 20 to 25 years for gas furnaces with air conditioners.


Regardless of the reason you are choosing to replace your present system, there are three factors you should consider—efficiency, refrigerant, and comfort.

Efficiency

The US Department of Energy sets the standards for rating the energy efficiency of heating and cooling systems. The rating number is an indication of how much energy (electric or gas) it takes to produce one unit of heating or cooling. The terminology differs for air conditioners/heat pumps and gas furnaces.

Refrigerants

Comfort

Innovations in the design of today's heating and cooling systems include features that eliminate the "heat pump chill" associated with older equipment. Two of the most significant are variable-speed blower motors and two-stage gas valves.

The most important consideration— involve your contractor early in the planning process.

Perhaps the most important aspect in planning a system replacement is to involve your contractor at an early stage in the process. There have been changes in building codes over the past years and the newer equipment has more stringent installation requirements. We often find during the evaluation process that home improvements such as finished basements can make the installation of some equipment impractical. Environmental Systems Associates provides free, in-home evaluations to ensure that you are aware of all the choices available to you.
