There are several factors to keep in mind when selecting and working with a heating and cooling (HVAC) contractor. The following tips can help you make an educated decision and recieve quality service:

1. Ask for a certified HVAC technician. Keep in mind that not all states require certification.
2. Your contractor should be licensed, well trained, and experienced to provide quality installations. Ask your contractor about his or her training, experience, and membership in contractors associations. Ask if he is insured and bonded.
3. Good contractors own and use refrigerant recovery equipment and are certified to handle refrigerant in cooling systems. Ask for proof of certification if applicable to your state.
4. Contractors should know how to properly size your home heating and cooling system(e.g., determine whether you need a two-ton or three-ton cooling system). Don’t use a contractor who wants to size your unit solely on the square footage of your house.
5. Ask your contractor to inspect your ducts for leaks, incomplete connections, and compatibility with the rest of your system.
6. Your air conditioner condenser should always match the indoor coil.
7. Have your contractor select an install location that provides for ease of maintenance. Make sure the inside coil can be reached for cleaning.
8. Always obtain a written contract or proposal before allowing your contractor to install a new system and be sure to ask about warranties.
9. Remember, the contractor who gives you the lowest bid may not be the best choice for you. Paying slightly more may get you better equipment and better service. Carefully evaluate a contractor’s proposal to ensure you get the equipment and service that best meets your needs.
10. Most contractors offer maintenance agreements to keep your system running smoothly for years to come. Also ask about the warranty length, what it covers and if there are extended labor warranties available.
11. Be sure to ask your HVAC contractor about Energy Star®-labeled heating and cooling products.
