Can I install my own furnace?

Yes, furnaces do fall into the permit zone. In most states, a furnace or mechanic permit is a requirement by law for those who need to fully replace a furnace. Furnace replacement and installation is a major home project requiring a great deal of work by installation teams and contractors.

How much is it to install a furnace?

Furnace Installation Cost New furnace installation costs typically range from around $2,500 to $6,000 for labor with professional installation. Prices for installation and labor cost will depend on a number of factors, like brand and unit size, but generally cost average of $4,200.

What size furnace do I need for a 1500 square foot home?

Reference a furnace size chart.
A 1,200-square-foot home will require between 35,000 and 75,000 BTUs. A 1,500-square-foot home will require between 45,000 to 90,000 BTUs. A 1,800-square-foot home will require between 55,000 to 110,000 BTUs. A 2,100-square-foot home will require between 65,000 to 125,000 BTUs.

Are high efficiency furnaces worth it?

A furnace with an AFUE rating of 95% will require significantly less fuel (natural gas) to heat your home than a unit with an 80% AFUE rating. While higher-efficiency furnaces tend to cost more upfront, they allow homeowners to save money on heating costs every year.

What size breaker do I need for a furnace?

Breaker Size Based on Wattage The exact amps an electric furnace requires is solely based on the size of the furnace and its performance capabilities; however, typically electric furnaces require a draw between 60 and 80 amps.

Does a furnace need to be grounded?

The “ground” that is required is the grounding path between the main burner and the board (sometimes called the ICM). Most modern furnaces require this path between the burner, through the chassis, and back to the board so that the flame rectification (flame sensing) will work.

What do thermostat letters mean?

But people are often confused by the system by which the low voltage wires are labeled, which can look different in an old thermostat than it does in a new one. Contrary to popular belief, the letters do not correspond to wire colors, but rather are used to indicate the various function signals controlled by each wire.

How large a furnace do I need?

A good rule of thumb for unit sizing is you will want a system that will provide you 40 to 45 BTUs of heat per square foot of your home. For example: If your home is 3,000 square feet, you’ll want a furnace that produces between 120,000 BTUs and 135,000 BTUs.

How often does a furnace need to be replaced?

How Often Should You Replace Your Furnace? The average furnace lasts approximately 18–20 years, though the actual number depends on the furnace itself and the level of care put into maintaining it during its lifespan.

Should I replace my ductwork?

“If your ductwork is over 15 years old, you probably should replace it. Ductwork has a maximum lifespan of 20-25 years. By 15 years, however, it begins to deteriorate, significantly reducing your HVAC system’s efficiency, so replacement is the prudent option.”

How many square feet does a 60000 BTU furnace heat?

A mid-sized home of 2,000 square feet would need approximately 50,000 to 60,000 Btu to heat it properly. With a less efficient furnace operating at 80 percent efficiency this would require a 60,000- to 72,000-Btu furnace.

How many square feet can a furnace heat?

For cooler climates, a very broad estimate of furnace sizing is to select one that generates 40 to 45 BTUs per square foot. At 40 to 45 BTUs per square foot, you’d need a 100,000 to 112,500 BTU furnace to heat your 2,500-square-foot home.

Should I replace furnace before selling house?

If your furnace is old and you’re looking to sell quickly it might be a good idea to replace it. It may be the cherry on top that a buyer needs to put in an offer. Plus, if the inspection turns up a problem with the furnace — even a minor one — the buyer may use that to negotiate for a lower price.

Are all new furnaces High Efficiency?

The lowest efficiency allowed by law for new gas furnaces is 78 percent, and some new models achieve 97 percent, near-total efficiency. The price of a furnace generally rises in step with its fuel efficiency. A furnace with a 90 percent AFUE might cost $1,000 more than a similar size unit with an 80 percent AFUE.

Should I replace my 30 year old furnace?

Regardless of the logic you follow, the 30-year mark is at or close to the maximum lifespan you should expect from your furnace. Even though furnaces can last 30 years or beyond, most experts recommend that you start shopping for a new furnace when your existing unit is 15 years old.
