1. Turn on the furnace and listen for noises. Squeaks and rattles could indicate a mechanical problem, lack of maintenance or just be symptomatic of an older furnace that is showing its age.
2. Ask the real estate agent or homeowner for the age of the furnace. A gas furnace will typically last 15-20 years. Also, keep in mind that older furnaces can be more expensive to operate.
3. Check the unit’s EnergySTAR® rating. If you’re lucky the label will still be attached to the unit. If not, the unit’s serial number can be used to contact the manufacturer for efficiency information.
Finally, for your peace of mind, it’s a good idea to have the home’s heating and cooling system inspected by a knowledgable pro. MR Plumbing Heating, Air Conditioning and Electrical can help check all your home’s vital systems to ensure there are no surprises down the road.
