Repairing, maintaining and replacing your comfort system requires choosing the right contractor to achieve your personal comfort.  When scheduling a free quote for a system replacement, it is best to set aside about 2 hours to allow for the comfort consultant to collect the necessary data you will need to receive a thorough proposal.  Our comfort consultant, Rusty Bailey has over 30 plus years in the industry and will discuss your comfort needs and expectations.  He will also perform a load calculation to measure indoor space, airflow, windows/doors, roofing and to help determine the correct equipment sizing and duct-work capacity.  Laying out a job requires precise measurements to ensure equipment dimensions fit in your access spaces.  Every home is different which makes every quote custom to your home.  Many think it is a simple process to give a price for a new system, however, there are many layers involved in providing that quote.  Equipment and technology changes and improves annually, so existing equipment is likely outdated and not compatible with new product lines.   Incorrect equipment capacity sizing can lead to comfort issues such as humidity problems, inefficient operation, higher utility bills, excess condensation and possibly over working a system which leads to higher failure rates and shortened equipment life.  Allowing time for your quote to be prepared accurately will help you get a return on your investment.

About R-410 RefrigerantWhat is R-22 refrigerant?

This is the chlorine based liquid gas used in air conditioners and heat pumps typically installed in residential properties prior to 2010. Without it your system will not comfort you. The EPA required R-22 systems to be phased out in 2010 and R-410 to be introduced which is more environmentally friendly than R-22.

Why is the price of R-22 refrigerant skyrocketing?

According to ACCA (Air Conditioning Contractors of America) the price of R-22 refrigerant has risen as much as 400% since early 2012 and we are not sure the price increase has hit the ceiling yet. The Environmental Protection Agency controls the production and import of R-22. They set limits on how much can be produced and imported each year, but failed to set limits for 2012. Until the EPA set these limits, manufacturers must produce 45% less R-22 than they did last year. This creates uncertainty in the marketplace and the manufacturers have increased their prices. The earliest the EPA will announce its decision is summer 2012 and nobody knows what the final 2012 limits will be.

As a professional contractor, our goal is to provide you with the best possible products, service and value so considering the unfortunate price increase with R-22 we feel it is important to inform you of the situation. We hope that Washington resolves this issue soon.

If you have a system that requires R-22 and it is aging or experiencing increasing refrigerant leaks or other failures, consider investing your money in a new, higher efficient system that handles R-410 which is more cost effective than experiencing expensive R-22 leak repairs. System replacement quotes are free and installations are performed by Kellam Mechanical technicians who are NATE and EPA refrigerant certified.


The U.S. Department of Energy is mandating that new installations and replacements of air conditioners and heat pumps are required to be 14 SEER or higher.  This applies to southern states and Virginia is listed in this requirement.  This will meet Energy Star standards.  Call Kellam Mechanical to get your high efficient system quote and start saving energy and money.
