When you convert to natural gas, you'll want equipment that is dependable, economical and long lasting. With O&R and PCL&P's reliable gas delivery system, plus a quality home heating appliance installed by a qualified contractor, you'll have the winning combination.

As manufacturers incorporate more technology into their processes, many top furnace and boiler brands are similar in overall performance. The one variable, therefore, is how well the system is installed. If a system is correctly sized, installed and maintained, it will perform at peak efficiency for many years.

Tips for selecting the right contractor

• Get estimates from at least 3 contractors who have done an onsite audit of your home or business to assess your specific needs.
• Before final selection, get written proposals clearly describing work to be done, equipment price and labor costs.
• Ask contractors to do a heat loss analysis to determine the right equipment size.
• Ask about manufacturer and contractor warranties; know what's covered and for how long.
• Make sure estimates are all for the same things: same size system, same efficiency and same accessories, such as thermostats and wiring.
• Ask how long you have to cancel a contract and find out if there's a penalty for doing so.
• Ask for at least three references and check customers' satisfaction with the contractor's services.
• Find out if the contractor offers annual maintenance service. This is recommended.
• Make certain the contractor is insured and bonded. Verify workers' compensation and liability coverage.
• Other questions to ask: Is a permit required from your local government? Who will be supervising the work? Will the contractor clean up and remove your old equipment? What is the timeline for the work? Will you be without heat or hot water for any length of time?
• Find out if a contractor is affiliated with a manufacturer. You may want to select a contractor who is factory-trained in working with a particular brand of heating system.
• Lastly, get a written contract. Understand payment terms and financing options before the job begins. This is in the best interest of you and your contractor.

Following these suggestions should help you hire the right contractor to work on one of the biggest appliances in your home or business. For homeowners, a heating system is one of the most expensive appliances purchased in a lifetime.
