Side by side for Farmington
Repair
Fix the failed part, keep the system
Best for: Furnaces under 12–15 years, first major failure, repair quote under 50% of replacement cost, sound heat exchanger.
Pros
- Most furnace repairs are modest — ignitors, flame sensors, capacitors, and board relays are all common, fixable items
- Right answer for any furnace under 12 years old with a sound heat exchanger
- Same-day fix in most cases; no permits, no install crew
- Buys time to plan a replacement on your schedule instead of in a January emergency
Cons
- — Repairs stack — the blower motor this year doesn't make the inducer next year any younger
- — An 80% AFUE furnace keeps burning 16% more gas than a 96% unit every month you keep it
- — Cracked heat exchanger ends the conversation — that's a CO safety issue, not a repair candidate
Replace
New 96% AFUE system, 20-year reset
Best for: Furnaces past 15 years, cracked heat exchangers, repair quotes over 50% of replacement, repeat failures two winters running, or anyone planning to add AC or a heat pump anyway.
Pros
- 96% AFUE vs an old 80% unit cuts the gas portion of the bill ~16%
- 10-year parts warranty resets the repair-cost clock to zero
- Two-stage and variable-speed options fix comfort complaints repairs never will
- High-altitude orifice kit + correct Manual J sizing done right this time
- Replacing in fall shoulder season beats replacing during a January cold snap at emergency pricing
Cons
- — Real investment — quality equipment is a significant upfront cost
- — A day of install disruption, permit, and inspection
- — Oversized 'bigger is better' replacements short-cycle — insist on a load calculation
Our take for Farmington
Use the 50% rule: if the repair quote exceeds half the cost of a comparable new furnace AND the unit is past 12 years, replace. Under 12 years with a sound heat exchanger? Repair it — almost every time. The one non-negotiable: a cracked heat exchanger means replacement, full stop. And get the heat-exchanger claim verified — ask to see the crack on camera. It's one of the most over-diagnosed 'failures' in the industry, and a free second opinion is cheaper than a furnace.
Furnace Repair vs Replace FAQ — Farmington edition
Which option fits a typical Farmington home best?
For most Farmington homes, we model both options at the in-home estimate using actual conditions (square footage, ductwork, insulation, 4,308 ft elevation, climate zone). No two homes are identical and the right answer often surprises people — that's why we never lock in a recommendation without seeing the house.
Do you install both options in Farmington?
Yes — we install and service both sides of this comparison across Farmington and Davis County. Free in-home estimate, written fixed-price quote before any work begins. $79 HVAC diagnostic (waived on approved repair) on repair-side visits.
How long should a furnace last in Utah?
15–20 years for a maintained gas furnace, sometimes 25 for a single-stage workhorse. Utah's high-altitude combustion runs slightly rich unless the furnace was properly orificed at install — un-derated furnaces age their heat exchangers faster, which is why some local units die at 12 and others cruise to 22.
A company says my heat exchanger is cracked. Should I just believe them?
Verify it. A real crack is visible on camera or detectable with a combustion analyzer reading. It's also the single most common pressure tactic in the industry because it converts a modest repair call into a full system replacement. We give free second opinions on heat-exchanger diagnoses — if it's truly cracked, we'll show you.
Is it worth replacing a working 80% furnace with a 96% one?
On gas savings alone, rarely — the payback is 10+ years. It becomes worth it when the 80% furnace is already past 15 years, when you're adding AC or a heat pump (shared blower), or when comfort problems (cold rooms, short cycling) need the variable-speed blower anyway.
