Selecting a Reputable Contractor
INSURANCE AND LIABILITY
When considering an HVAC contractor, ask to
see documentation that they carry general liability insurance to protect
your property as well as workers compensation insurance on their
employees. Lack of adequate insurance could be a major problem
for you if someone is injured on your property. An air conditioning
contractor should always have these types of insurance and this will
save you from a claim against your homeowner’s policy in case of an accident.
Choosing an HVAC contractor should include checking with the department of licensing. Be sure that the HVAC contractor’s license is current and check if the department of licensing has a history of disciplinary actions or complaints published on their website.
Another source for finding a competent HVAC contractor is the local permits office for your municipality. The municipal inspectors know the HVAC contractors who do good work from the HVAC contractors who do poor work.
A good HVAC contractor should inspect your existing air conditioner and collect a wide range of information about your home, how many windows and type, which direction they face, and R-value of the insulation. The contractor uses all of this information to calculate the heat load to verify that the existing equipment is correctly sized and proposed equipment is also correctly sized.
