Expect a home evaluation:
- The contractor should spend significant time inspecting your current system and home assessing your needs.
- The heating and cooling system size is based on the size of your house, level of insulation, and windows.
- An inspection of your duct system (if applicable) for air leaks and insulation and to measure airflow.
Get written, itemized estimates:
- Compare cost, energy efficiency and warranties of at least 3 contractor’s bids.
- A lowest price may not be the best deal if it’s not the most efficient (your energy costs will be higher).
Get it in ink:
- Sign a written proposal with a contractor before work gets started.
- The contract protects you by specifying project costs, model numbers, job schedule and warranty information.
Purchase ENERGY STAR products:
- They meet strict energy efficiency guidelines set by the EPA.
- They offer significant long-term energy savings.
- Contractors should be able to show you calculations of savings for ENERGY STAR heating and cooling equipment.
