When to Replace a Furnace
Many times it is more cost-effective to have a furnace repaired, rather than replaced. It may be best to buy a new one if the furnace is over 15 years old, if there is a common problem in the neighborhood with the furnaces placed in by the builder, if the heat exchanger or control module no longer work. The three basic types of heaters include gas, oil, and heat pumps (these are systems that have heat and air conditioning connected to the water pipes). Below are a few of my tips that I used when buying a new furnace for my home. Depending upon your skill level and time you may wish to install your own furnace.
1. Replace your furnace before needed, in the summer you may find lower prices and better availability of days and times for estimates and installation.
2. Check with the Better Business Bureau before calling for an estimate.
3. Have the model, serial number, and photo of your current furnace ready before making a call.
4. Make sure the salesman comes in person to calculate estimate.
5. Ask as to the length of time for installation.
6. If a pump furnace/heat pump is being installed, be aware of water shut off valves and inform neighbors of water shut off as needed.
7. Be home, watch the process, and take photos as the unit is being installed.
8. Make sure paint is available for any possible touchups to surrounding drywall or furnace door.
9. Mark your calendar to replace filter (typically every thirty to sixty day--see manufacturer’s instructions). Filter replacement will depend upon use, climate, geography, allergies, pets etc.
10. Purchase extra filters and store them for easy replacement.
11. Use LED (light-emitting diode) candles, as wax candles produce soot that clog filters.
