ABOUT THIS SERVICE

FURNACE INSTALLATION & REPLACEMENT
SIZED RIGHT FOR UTAH WINTERS

When your furnace fails at the worst time or repair costs rival replacement, installing new equipment right matters. Utah's -10°F to 107°F swings stress heating systems harder than mild climates. Elevation at 4,200–4,800 feet reduces air density. This affects how the furnace burns gas. Manual J load math accounts for home square footage, insulation, duct sizing, and Utah's extreme winter lows. This stops undersized units that can't keep up during January cold snaps. It also stops oversized systems that short-cycle and waste gas.

You might be replacing a 25-year-old Lennox with a cracked heat exchanger. Or upgrading a 70% efficiency Carrier to a 96% unit for lower Dominion Energy bills. Or switching from a boiler to forced-air. Or installing in new builds. The scope covers gas line checks, electrical work, ductwork changes if needed, city permits, combustion tests, and carbon monoxide testing. Most swaps finish in one day.

Installs use Lennox, Trane, Carrier, Bryant, Rheem, York, and Goodman furnaces. All backed by maker warranties. Financing is available with $0 down and 90% approval rate. Serving Salt Lake County, Utah County, Davis County, Summit County, Wasatch County, and Tooele County.
WHAT'S INCLUDED

COMPLETE FURNACE INSTALLATION & REPLACEMENT
COVERAGE IN UTAH

From a full furnace replacement to upgrading to high-efficiency equipment, we handle every step of residential furnace installation across the Wasatch Front. Our licensed technicians size equipment correctly for Utah's elevation and extreme winters, and complete most installs in a single day.
🏠
New Furnace Installation
Installing a furnace in new builds or a home that used boiler heat requires running new gas lines. We add or change ductwork, install the furnace and air handler, and wire to your electrical panel. We add combustion air and route condensate drains for high-efficiency models. Full-load testing happens before final sign-off. Manual J sizing stops undersized equipment failures. Builders often install stock 80,000 BTU units in homes that need 100,000+ BTU for Utah's sub-zero overnight lows. Carbon monoxide testing verifies safe operation. City permits and checks come with every install. No cutting corners on safety or code.

Second Opinion on Replacement
Got a quote for furnace swap but not sure it's needed? A full check covers heat exchanger look with camera proof, burner flame analysis, gas pressure testing, blower motor amp draw, limit switch operation, and vent draft measure. Then we give you an honest view of whether repair or swap makes financial sense. If your furnace has 5+ years of safe, reliable service left, you'll hear that upfront. No pressure into unneeded equipment buys. Cracked heat exchangers and failed gas valves need quick swap for safety. Minor issues like ignitors or flame sensors are cost-effective repairs. Check fee applies. Waived if you proceed with swap or major repair through the same visit.

Furnace Sizing & Load Calculation
An oversized furnace short-cycles, wears out blower motors, and gives uneven heat. An undersized unit runs nonstop during -10°F January nights. It never hits thermostat setpoint. In Draper and South Jordan, we often find builder installs undersized by 20,000 BTU. The furnace runs nonstop during a cold snap and utility bills spike. Manual J load math runs on every install. We factor in home square footage, insulation R-value, window U-values, duct leakage, and Utah's extreme winter lows. This matches equipment capacity to your actual heating need. Elevation fixes account for reduced air density at 4,500 feet. Included free with every swap quote.

Carbon Monoxide Testing & Safety
During winter inversions, windows stay closed for weeks. A furnace with a cracked heat exchanger or poor combustion vents carbon monoxide into living spaces. Utah's inversion season (November through March) traps pollution and risky gases indoors. Every furnace install includes post-install carbon monoxide testing. We test at the furnace cabinet, at nearby registers, and in sleeping areas. Combustion analysis verifies proper air-to-fuel ratio. Draft testing confirms exhaust gases vent safely outdoors. All furnaces installed meet Utah code needs for combustion air intake and fresh air supply. Safety is not up for debate.

HOW IT WORKS

OUR FURNACE INSTALLATION & REPLACEMENT
PROCESS

STEP 01
CALL OR BOOK
Call (801) 997-1617 or book online. Real people answer 24/7. No phone trees, no voicemail during business hours. Your on-site check and quote gets booked usually same-day or next-day. Arrival windows fit your schedule. No vague all-day slots.
STEP 02
ON-SITE ASSESSMENT
A licensed tech checks your existing system. They measure your home's square footage and insulation. They check ductwork for leaks and proper sizing. They run Manual J heating load. This accounts for Utah's elevation and winter extremes. Then they discuss your goals. This covers budget, efficiency targets, noise levels, and smart thermostat picks. Then they present options.
STEP 03
UPFRONT QUOTE
You get a written quote. It covers equipment specs, AFUE rating, maker warranty details, and total installed cost. All itemized so you see exactly what you're paying for. No pressure to decide on the spot. If you want time to think, compare quotes from other firms, or talk with family, take all the time you need.
STEP 04
INSTALL & TEST
Install covers removing old equipment and mounting the new furnace. We upgrade electrical if needed and pull city permits. We test gas line pressure and run combustion analysis. We verify proper draft and test carbon monoxide levels. We check airflow at every register and run full-load heat cycles before final payment. Most home installs finish in one day. Any ductwork changes or electrical panel upgrades may stretch to 1.5 days.
IS IT TIME TO REPLACE?

SIGNS YOUR FURNACE
NEEDS REPLACEMENT

📅
System Over 20 Years Old
Utah furnaces cycle hard November through March. That's five straight months of daily heating. By year 20, heat exchangers crack from thermal stress. Blower motors fail. Efficiency drops 15–20% from original specs. Watch for the furnace struggling to hold 68°F on a -10°F night. Or yellow flame instead of blue from burner wear. Or the cabinet rattling from worn mounts. If you're fixing the same aging furnace every winter, swap pays back. You skip service calls, lower gas bills, and gain peace of mind during January cold snaps.
Don't ignore this
💰
Repair Costs Exceed Half the Replacement Cost
If your heat exchanger cracked and the repair quote is $2,800 on a 15-year-old furnace, swap makes more sense. A new furnace costs $7,065–$11,415 installed. It qualifies for Dominion Energy rebates. It includes a 10-year parts warranty. We walk you through both options with real numbers. No pressure either way. Safety always comes first. A cracked exchanger is never safe to run.
Don't ignore this
⚠️
Carbon Monoxide Risk or Cracked Heat Exchanger
A cracked heat exchanger lets combustion gases with carbon monoxide mix with household air. During Utah's winter inversions, windows stay closed for weeks. CO builds up indoors undetected. Symptoms cover headaches, dizziness, and flu-like illness that improves when you leave the house. Visual cracks, sooting around the furnace, or a steady yellow flame all signal quick swap. No repair exists for a cracked exchanger. The entire furnace must be swapped for safety. This is not up for debate.

COMMON QUESTIONS

FURNACE INSTALLATION & REPLACEMENT
FREQUENTLY ASKED QUESTIONS

Most home furnace swaps range from $7,065–$11,415 for 80% efficiency gas units. High-efficiency condensing furnaces (96%+ AFUE) run $9,681–$13,392. Price depends on system size (BTU capacity), AFUE rating, and any electrical, gas line, or ductwork upgrades needed. Higher-efficiency units cost more upfront. But they qualify for Dominion Energy rebates up to $800. They pay back through lower winter gas bills. We give a flat-rate quote after the on-site check, before any work starts.

Furnace under 12 years old? Repair usually wins if the fix costs less than half the swap price. It also can’t involve a cracked heat exchanger. System over 18 years old? Or facing a heat exchanger swap that’s not even doable on most models? Swap often pays back faster. You gain a new 10-year parts warranty. You get lower gas bills from better efficiency. You skip seasonal breakdowns. We walk you through both options with real numbers. Never pressure you either way. Safety always comes first. Cracked heat exchangers mean quick swap.

Most home furnace swaps finish in one day. Typically 6–8 hours for a standard swap on existing ductwork and gas lines. Gas line upgrades, electrical panel changes, or ductwork changes can stretch the job to 1.5 days. Adding combustion air intake or routing condensate drains for high-efficiency models adds time. City checks get booked within 48 hours of finish. You’ll have heat back the same day the new furnace goes in. Final testing, combustion analysis, and carbon monoxide check are done before the install crew leaves your home.

Available brands cover Lennox, Trane, Carrier, Bryant, Rheem, York, and Goodman furnaces. All come with maker warranties from 5–10 years on parts. Heat exchanger warranties typically run 10–20 years. This depends on model and efficiency. Your on-site check covers a talk about brand options, AFUE ratings, noise levels, and warranty coverage. Equipment picks fit your budget and long-term reliability goals. No pushing the highest-margin units.

$0 down financing with a 90% approval rate is available on all furnace swaps. Spreading a $5,500 system over 60 months makes the monthly payment doable. You start saving right away on lower gas bills. Your old furnace was wasteful. Your tech walks through current financing options, interest rates, and term lengths when giving your quote. Approval picks typically come within minutes. You can book install the same week if needed.

Yes. All techs are Utah state licensed HVAC contractors. The company carries full liability insurance. City permits are required by law for all Utah furnace swaps. We pull them for every job. We book checks to confirm code fit. You’ll get permit docs and final check sign-off before we consider the job done. Licensing and insurance protect your home, your money, and your family’s safety through the entire install.

Utah’s elevation (4,200–4,800 feet in the valleys) cuts air density by about 15% vs. sea level. Lower air pressure affects airflow math and how the furnace burns gas. Equipment sized for Denver or Phoenix often fails here during -10°F overnight lows. We run a Manual J load math on every install. This factors in elevation, home insulation, window U-values, and duct leakage. This stops undersized units that can’t keep up during January cold snaps. It also stops oversized units that short-cycle and wear out blower motors.

Fall is the best time to swap your furnace in Utah. September through October gives faster booking and better equipment stock. No rush fees. Peak winter months bring wait times that stretch to weeks. Installing before Utah’s first sub-freezing nights hit in November means you’re set when cold hits. You skip suffering through -10°F overnight lows waiting for parts. Fall installs let you lock in current pricing before winter demand drives costs up. You won’t pick between a rushed install during a January freeze and shivering through the night. Fall gives you options instead of rush.
