Ask the right questions before you hire.

It is important to get all the facts in order to make informed decisions and avoid costly mistakes. Ask every prospective contractor for:

• A demonstrated commitment to quality.  Insulation and windows and heating and cooling equipment must be properly-sized and installed to provide the efficiency and performance they were designed to deliver.
• A list of references and credentials regarding the quality of its installation and/or service work
• A written, itemized estimate.  Never accept estimates by phone. When comparing estimates, consider cost, energy efficiency and warranties—not just price. A cheaper but less energy-efficient product could raise your energy bills. 
• A written contract, before work begins, that includes specified project costs, model numbers, the job schedule and warranty information.

For heating and cooling equipment

• A load calculation that uses your home’s design data to determine correct equipment size. Never hire a contractor who sizes your unit based solely on your home’s square footage.
• An agreement to properly inspect your home’s duct system and provide any needed sealing, repairs or modifications.
• Confirmation that new cooling equipment will be installed according to the manufacturer’s specifications. This includes verifying that the system airflow across the coil and the refrigerant charge are within the manufacturer’s specifications.
