Choosing an HVAC Contractor

"I couldn't be more pleased with the recent HVAC system replacement your company performed at my home. ESA's professionalism and attention to detail was evident throughout the entire process—from the initial quote through the actual install."
— S.W., Ellicott City

Many factors go into a decision to modify or replace your heating and cooling system…

the age and condition of your existing HVAC system
the size and age of your home;
existing characteristics such as basements, attics, and insulation;
specific problems such as uneven air or heat distribution in your home or excessive indoor humidity;
and personal lifestyle.

The contractor you choose should take the time to visit your home and examine all of these factors. He should then provide you with a detailed, written plan to meet your individual needs.

Recommendations from The Air Conditioning Contractors of America

The Air Conditioning Contractors of America (ACCA) suggests that consumers also consider the following items when choosing a contractor:

Your contractor is properly licensed. In Maryland, this means having a Master's "HVACR" license, as well as an electrical and/or a gas fitter's license. Your contractor's technicians should all carry an apprentice or journeyman's HVACR license and be certified to handle refrigerant.
Your contractor carries adequate business and workers compensation insurance. In Howard County, a performance bond is not a requirement.
Your contractor has adequate technical and practical experience. Technicians who are "NATE Certified" have passed rigorous exams by the North American Technician Alliance to certify that they have the necessary mechanical knowledge and expertise to service heating and cooling systems.
Your contractor provides you with a detailed written contract that specifies the manufacturer and model numbers of the equipment to be installed, whether the old equipment will be removed, what the warranty covers, and any applicable rebates or tax credits.
Your contractor is willing and able to provide warranty service.

Be sure that you examine factors such as references, reliability and quality of service in addition to price.
