Ask the Right Questions Before You Hire

It’s important to get all the facts so that you can make informed decisions and avoid costly mistakes, before any work begins. Ask every potential contractor for:

  • A list of references and credentials regarding the quality of their installation and/or services. 
  • A written, itemized and dated estimate. Never accept estimates by phone. Instead, ask the contractor to send you a copy of their estimate with details of what you have discussed. When comparing estimates, consider the entire cost, which also includes energy efficiency and warranties, not just price. A cheaper, but less energy-efficient, product could raise your energy bills.
  • A written contract that includes specified project costs, model numbers and job schedule, as well as and any warranty information.

Also, make sure that the contractor you’d like to hire has a demonstrated commitment to quality. Be friendly, yet persistent, when you discuss options, and don’t sign any contract to begin work until you feel confident that you’ve hired the best person and/or company. 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. Keep in mind the adage “Measure twice, cut once.”

Heating and Cooling Equipment

For heating and cooling equipment, you will need:

  • Your contractor to perform a load calculation, that which 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 necessary sealing, repairs or modifications.
  • Confirmation that new cooling equipment will be installed according to the manufacturer's specifications. This includes verification that the system airflow across the coil and the refrigerant charge are within the manufacturer's specifications.
