—Install a programmable thermostat. These can save you up to 10 percent on your energy bills, since they allow you to avoid overheating your house when nobody’s home, for example.
It’s important to hire a well-trained and properly licensed professional to keep your furnace in tiptop shape. Heating and cooling systems comprise one of the home’s most complex systems. Also, many states require heating and cooling professionals to be licensed.
When hiring a company to maintain your furnace, ask for and check references. Also, confirm that the company is appropriately licensed, insured and bonded.
