How can you tell it is time to replace your furnace?

Repairs every winter

When you call for repairs each heating season, the furnace may be telling you it is done. We check the whole system to see if replacement makes more sense than another fix.

Bills climbing

Your energy bills go up even though your habits have not changed. We check whether the furnace is losing efficiency and costing you more to run.

Rooms never warm

Some rooms stay cold no matter how high you set the thermostat. We check whether the furnace can still deliver heat evenly through your home.

Furnace outlives the house

The furnace has been there longer than you have owned the home. We check its condition against what modern units can provide.

Heat exchanger flagged

A technician found a crack or damage in the heat exchanger. We check this component carefully because it affects safety and performance.

More dust than before

You notice extra dust settling on surfaces since the furnace started running. We check whether the unit is pushing debris through your ducts.

Noisy start-up

The furnace makes loud pops, rattles, or groans when it fires up. We check what is causing the noise and whether the unit can run safely.

Remodel changed the load

You added a room, finished a basement, or changed your home's layout. We check whether the old furnace can still handle the new size of your home.

Another company's quote

You have a replacement quote from another contractor and want a second look. We check the proposal and give you our honest opinion at no charge.

Why does Utah's climate and code decide furnace size?

Salt Lake City airport records 5,154 heating degree days; Provo records 4,968; Ogden records 5,508. Bountiful sits at about 4,298 feet elevation; Provo sits at about 4,554 feet. Utah law requires load calculations by a qualified person. The ENERGY STAR program reports that improper installation can cut efficiency by up to 30 percent.

Sizing by the standards

The industry standard Manual J is the load calculation. Manual S governs equipment selection, with size limits against short cycling and an altitude appendix. Manual D covers duct design. Utah law requires load calculations by a qualified person. Amana lists a high-altitude kit.[1]

Efficiency tiers

AFUE stands for Annual Fuel Utilization Efficiency - the share of fuel turned into heat. Federal rules set 80% AFUE as the minimum today. A 95% minimum applies to furnaces made from December 18, 2028; a petition to delay to 2030 is pending, with no decision yet. Lennox offers a lineup from 80% to 99%.[2]

Venting and combustion air

Condensing furnaces vent in PVC, using 2- or 3-inch pipe, with one pipe or two. Utah adopts the 2024 fuel-gas code and the 2021 residential code. Combustion air is provided per manufacturer and local code. A Utah amendment allows existing Category I furnaces in living space to stay under six conditions.[3]

Permits and licensing

Utah law requires a licensed HVAC contractor for installation, repair, and replacement. Gas work must be done by a trained and certified person. Permits are required in Salt Lake City, Davis County, Ogden, and West Valley City. Operating without a permit when one is required is unlawful.[4]

[1] ENERGY STAR - replacing heating and cooling equipment. [2] ANSI/ACCA 4 QM – 2019 (R2024), Maintenance of Residential HVAC Systems. [3] Utah Code Title 15A, Chapter 3 - statewide amendments to the building codes. [4] Utah Code Title 58, Chapter 55 - construction trades licensing. [5] Full source list: data-sources

We show you options - 80%, 90%, or 96%, furnace or heat pump - with one flat all-in price. We also offer a free second opinion on any competitor's replacement quote.

Which heating option fits your home?

Here is how the three main gas furnace options compare for a Wasatch Front home.

80% AFUE furnace

  • ✓Best for: Homes with metal venting already in place.
  • ✓This is the current minimum under federal rules.

90%-class furnace

  • ✓Best for: A step up from an 80% furnace.
  • ✓Amana models reach up to 92% and Lennox 93%; these are condensing units with PVC venting and a condensate drain.

96% or higher furnace

  • ✓Best for: Homes where efficiency matters most.
  • ✓A condensing model; Amana requires PVC venting, 2- or 3-inch, and condensate drained.

Dual-fuel pairing (heat pump plus furnace)

  • ✓Best for: Homes that want electric heat most of the time.
  • ✓Amana and Lennox make dual-fuel capable models; a dual-fuel kit is needed. We file rebate paperwork where a program applies.

What does a proper furnace installation deliver?

Sized to your home

We size the furnace to the house and its elevation. Utah law requires sizing by a qualified person.

Verified performance

Improper installation can cut efficiency by up to 30 percent, according to the ENERGY STAR program.

Ductwork checked

Ducts lose 20 to 30 percent of the air they carry, per the ENERGY STAR program. Sealing can improve efficiency up to 20 percent.

Code-compliant setup

Combustion air follows manufacturer requirements and code. We handle venting and condensate to code, pull a permit, and coordinate inspection.

Warranty registered

Lennox offers a 5-year base parts warranty, or 10 years with registration within 60 days. Amana offers 5 years unregistered, or 10 years registered within 60 days. We register your manufacturer's warranty for you.

Safety verified

Carbon monoxide is checked during commissioning. The CPSC recommends alarms on every level of the home. Utah code requires alarms on each level.

What installation problems do we solve?

Oversized old furnace

The industry standard sets size limits to prevent short cycling. We size the furnace to your house.

Venting a condensing furnace

Amana specifies PVC, 2- or 3-inch, sized by input, elbows, and run length, with one pipe or two and condensate drained. We route both.

Furnace in a closet or living space

Utah's building code amendment allows existing Category I furnaces in occupiable rooms under six conditions. We check them before quoting.

Elevation adjustment

Bountiful sits at about 4,298 feet and Provo at about 4,554 feet. The industry standard includes an altitude appendix, and Amana offers a high-altitude kit. We adjust for it.

Electrical circuit

Amana calculates circuit ampacity from blower and inducer amps, with wire size per the electrical code. We confirm the circuit.

Dual-fuel pairing

Amana makes dual-fuel capable furnaces with a dual-fuel kit and a switchover setting. We pair and program it.

What moves the price of a furnace install?

We give one flat all-in price in writing, with options shown. There is no pressure and no quote that expires tonight. The drivers that set the price are published for you to see. Blue Best quotes an exact price in writing before any work begins.

The price drivers are duct work, electrical work, the efficiency tier, the heat load, and venting changes. We file rebate paperwork where a program applies and offer a free second opinion on any competitor's replacement quote.

Quoted free

Written options - you see every choice in plain terms.

Quoted upfront

80% furnace - a like-for-like swap of the old unit.

Quoted upfront

Condensing furnace - a 90% or 96% model with new venting and condensate.

Quoted upfront

Dual-fuel pairing - a furnace matched with a heat pump.

Quoted upfront

What does Blue Best guarantee in writing?

On new equipment installs

a 1-year labor warranty - extendable for customers on a Blue Best Maintenance Plan - the parts warranty (typically 10 years on qualifying Lennox and Amana equipment) registered for you, and no-lemon coverage on major components like compressors and heat exchangers.

On any quoted work

the price you sign is the price you pay - change orders require your approval before we do the work. Plus a free second opinion on any competitor's replacement quote (no blanket price-match - sometimes our honest answer is "take their deal").

What we won't promise

real-world comfort depends on duct condition, insulation, and infiltration, so we disclose those dependencies rather than guarantee a number. The 5.0 rating from 2,900+ reviews is the audit trail.

What homeowners ask about furnace installation

The install includes the unit, venting and combustion air, and a thermostat. We pull the permit and coordinate the inspection. We haul away your old furnace. Commissioning covers gas pressure, temperature rise, and a carbon monoxide check. We register the manufacturer's warranty for you. A 1-year labor warranty on the install is included.

AFUE stands for Annual Fuel Utilization Efficiency, which is the percentage of fuel turned into heat. Federal rules set 80 percent as the minimum today. A 90-percent-class furnace is condensing and typically achieves 92 to 93 percent AFUE. A 96-percent model is also condensing and requires PVC venting and a condensate drain. We price the options.

Amana specifies PVC pipe, either 2-inch or 3-inch. The size is based on the input, number of elbows, and run length. The system uses one pipe or two. Condensate is drained away. Utah adopts the 2024 fuel-gas code. We install venting and condensate to code.

Lennox offers 5 years parts base, or 10 years with registration within 60 days. Amana offers 5 years unregistered, or 10 years registered within 60 days, and a heat exchanger warranty of 20 years unregistered. We register the manufacturer's warranty for you. A 1-year labor warranty on the install is included.

Sometimes. We file rebate paperwork where a program applies. Programs vary by utility and equipment. Ask when you call.

Manual J is the industry standard for sizing heating and cooling equipment. It calculates how much heat a home loses and gains. Manual S sets size limits for the equipment. Utah law requires load calculations by a qualified person. The ENERGY STAR program states that improper installation can cut efficiency up to 30 percent.

Federal rules require 95% AFUE for furnaces made from December 18, 2028. A petition to delay the standard to 2030 is pending with no decision yet. The standard is on the books today. Existing 80% furnaces are unaffected by this rule.

Yes. Utah law requires a licensed HVAC contractor. Gas work must be done by a certified person. Permits are required in Salt Lake City, Davis County, Ogden, and West Valley City. We pull the permit and coordinate the inspection.

Yes. Amana and Lennox make dual-fuel capable furnaces. A heat pump can be paired with a gas furnace using a dual-fuel kit. We price a furnace or heat pump. We file rebate paperwork where a program applies.
