The modern buildings and houses today have very sophisticated plumbing and mechanical systems apart from centralized cooling, heating and ventilation mechanisms.
There are different methods and measures which are available for evaluating the effectiveness of your air conditioning and heating units. For the air conditioners, this efficiency is usually measured in terms of SEER and for the heat pump it is usually measured by the HSPF.
Whether you are going for a fresh installation of the air conditioning or heating unit or are on lookout for efficient air conditioning or heating services, getting the services of a good contractor is as much important as the choosing these units. Proper maintenance is also as necessary as installation itself for the unit to function with safety, reliability and maximum efficiency.
Few suggestions for selecting a good Air conditioning and Heating Contractor:
When you are on a lookout for a air conditioning and heating contractor, you should seek opinion of your relatives as well as friends living in same locality as you, who would be able to recommend you the one's they had a nice experience with.
There are two associations: Air Conditioning Contractors in America (ACCA) and Sheet Metal and Air Conditioning Contractors national Association (SAMCNA) to which many of the reputed and big contractors belong. The websites of these associations would provide you with all details of heating, cooling, ventilation and refrigeration contractors for all areas of USA. You should choose the contractors who have technicians who have certifications from some reputed agency.
Please ensure that the contractors for air conditioning and heating personally visit the installation site and provide you with the requisite quote.
An experienced estimator will visit your hose for survey and will base his proposal on the proper heat load calculations. If old installation is to be repaired, estimator will enquire you about the problems and would offer intelligent solutions along with estimates on cost.
A experienced contractor will give you estimate on the yearly operation cost for the equipment he is going to install on the basis of cooling/ heating load calculations.
It is good to seek estimate from several contractors but you should not base your decision just on low cost being offered. Reliable contractors are expensive and usually have some staff and office.
Payments schedule of the contractors vary from company to company but is not too difficult to understand. You must insist on receipts of all payments you make to the contractors.
It is also essential that these contractors have property damage insurance and have the public liability. If you want, you can ask for the references and also any questions if you have.
