Most people take for granted the comfort provided by their central air conditioner, heat pump or furnace until something goes wrong and the unit needs to be serviced or replaced. When this happens it’s important to contact a quality heating, ventilation, air conditioning and refrigeration (HVACR) contractor who is knowledgeable, skilled and qualified for the job.

The HVACR industry is highly technical and can be intimidating to those that know nothing about how the equipment works in their home. It’s important that consumers are educated about the product they are buying or having serviced. The first step is to understand what is required of the contractor by the local jurisdiction. To insure satisfaction the following questions should be asked of a prospective HVACR contractor.

Are you licensed? 


The State of Maryland requires that all HVACR contractors be licensed. If they cannot produce proof of licensing, this should raise a red flag. Written estimates and contracts should have the license number of the contractor on them.

Are your technicians CFC certified? 


Any technician working with refrigerant needs to have a certification mandated by the U.S. Environmental Protection Agency showing that he or she is trained and certified in the proper techniques for recovering, recycling, reclaiming and disposing of used refrigerant.

Do you carry the proper business and workman’s compensation insurance required to do the work?

The State of Maryland requires that all HVACR contractors have the proper insurance to do business.

Are you going to give me your quote in writing? 


It is the practice of an HACC Contractor to provide clear and thorough estimates of the work to be performed in writing. This document will outline what the responsibilities are for both the contractor and you the customer.

Do you perform warranty service throughout the warranty period? 


Some contractors only install – they don’t service the equipment.

Don’t consider price only. 


Be sure that you are comparing “apples to apples” when considering more than one contractor. Be sure they are quoting the same size unit and offering the same level of service.

Will you provide references? 


Finding out if other customers are satisfied is a great way to decide which contractor is best for your situation.

And, finally, ask if the contractor is a member of the Heating and Air Conditioning Contractors of Maryland trade association.
