Heating & Air Conditioning in Maplewood, MN: Choosing a New Furnace

The furnace in a heating, ventilation, and air conditioning (HVAC) system may need to be replaced at some point in its operational lifespan.

Determining which model will work for your house, however, needs some deeper research.

This Old House guest contributor Richard Trethewey says in a reader feedback column that you cannot wait until inclement weather to conduct the replacement.

Minnesota’s northern latitude makes it vulnerable to winter weather until deep into April, thanks to cold air coming in from Canada.

Although temperatures may begin to rise as the season changes, you may have to think ahead about gradual fixes to your HVAC system.

If you feel that the time has come to replace the furnace, experts in heating & air conditioning in Maplewood, MN like Metro Heating and Cooling are the ones to call for the job.

Through a Looking Glass

The selection process for a new furnace is at the least, tedious.

Many HVAC specialists recommend having an experienced service or installation technicians come over to reevaluate the house along a number of factors.

These include:

  • Insulation level
  • Current state of the furnace
  • Recent fuel bill data ( particularly the type of fuel your utility provider supplies)

The technicians will check over your furnace to see whether it really needs to be replaced.

One sign of an older furnace is when it has a lower annual fuel utilization efficiency (AFUE rating), meaning it does not burn a significant part of the fuel.

Output in terms of British thermal units (BTUs) are also considered and matched with the size of the house.

Most HVAC professionals say that choosing a furnace with lower BTU ratings for a large house is often ineffective.

Your furnace specialist will assess the overall size of your house and recommend which furnace type and size will be appropriate.

For the Long-Term

Though a newly installed furnace will not give you a lot of maintenance concerns, it will need to be properly maintained, anyway.

To this end, consult Maplewood, MN furnace repair and maintenance specialists about the kind of care your new furnace needs, and the ideal professional maintenance schedule.


HVAC units do not last forever, even if they have been manufactured with the most advanced technology.

You can be assured, however, that a furnace that was properly vetted and selected for your home by companies like Metro Heating and Cooling will be a fine investment.
