5-star Lehi matches, verified.

★★★★★ 24/7 Emergency

“Called at 11pm with no-cool at 98°F. A licensed tech was at my door by 12:20am. Refrigerant leak at the coil fitting. Patched, recharged, cool by 1:30am. Emergency fee was $175 — totally fair.”

★★★★☆ Maintenance

“Annual dual-system tune-up. Tech found a weak capacitor on the furnace and replaced it on the spot — $180. Professional, respectful of the house, left everything clean. Only minor gripe: scheduling window was 3 hours.”

★★★★★ Furnace Repair

“Gas furnace stopped on the coldest night of the year. Matched tech diagnosed the flame sensor in 10 minutes, cleaned it, system back up. $145 all in. Asked about a tune-up — honest answer was 'you're fine, just replace the filter.' I trust these guys.”

★★★★★ System Installation

“Replaced our 14-year-old 4-ton with a variable-speed heat pump. The contractor actually ran a Manual-J and flagged that a 3.5-ton was a better fit — saved us $1,800 off the bigger quote from the last guy. Rebates handled. 10/10.”

★★★★★ Heat Pump

“Got a cold-climate heat pump installed before winter. At -5°F last month it kept up no problem. Matched contractor knew the Xcel rebate process cold — filed the $2k credit and $1,400 utility check landed in 3 weeks.”

// Lehi seasonal guide

Your Lehi HVAC year-round calendar.

Climate-specific recommendations tuned for Lehi County weather patterns. Aligned with DOE guidelines and ACCA standards.

🌱

Spring (March–May)

  • Replace HVAC air filter (MERV 8–13 recommended for Lehi allergens)
  • Schedule pre-summer AC tune-up: coil cleaning, refrigerant charge verification, capacitor amp-draw test
  • Clear 2-foot radius around outdoor condenser; trim any encroaching vegetation
  • Test-run the AC for 15 minutes on a cool day to confirm proper operation before peak demand
  • Inspect and reseal any duct leaks in attic spaces — pre-summer is the ideal window
☀️

Summer (June–August)

  • Replace or wash filter monthly during peak cooling season
  • Keep thermostat set points consistent — 78°F is optimal for cost-to-comfort in Lehi
  • Check condensate drain line monthly; clear with 1/4 cup white vinegar if slow
  • Close blinds on south/west-facing windows during 10am–4pm peak solar gain
  • If your bill jumps 20%+ month-over-month, schedule a diagnostic before it becomes a breakdown
🍂

Fall (September–November)

  • Schedule pre-winter furnace/heat pump tune-up: heat exchanger inspection, combustion analysis, ignition check
  • Replace humidifier pad if equipped
  • Test carbon monoxide detectors and replace batteries
  • Clear leaves and debris from around outdoor heat pump unit
  • Consider switching to a pleated filter (MERV 11) for winter particulate load
❄️

Winter (December–February)

// Contractor scam red flags

7 ways to spot a bad Lehi HVAC contractor.

Per the BBB, HVAC is a top-10 scam category. Every network contractor in Lehi passes all 7 checks.

01
⚠ No state license visible on truck or business card

Every U.S. state except Wyoming requires HVAC contractor licensing. A legitimate pro will display the license number prominently.

02
⚠ Quotes over the phone without seeing the system

Honest contractors diagnose before quoting. A price given sight-unseen is a sales pitch, not an estimate.

03
⚠ Cash-only or significant discount for cash

Legitimate businesses accept card, check, and financing. Cash-only is a red flag for unlicensed work or tax avoidance.

04
⚠ Pressure to replace when repair is possible

The rule of thumb: if repair cost exceeds 50% of replacement AND the system is 10+ years old, replace. Otherwise, repair is usually right.

05
⚠ Refrigerant recharge without leak detection

EPA Section 608 requires leak repair before adding refrigerant to any system with a known leak >15% annual loss. Shops that skip this are cutting corners.

06
⚠ No written quote before work begins

Verbal quotes don't protect you. Your quote should be flat-rate, itemized, and signed by both parties before any work starts.

07
⚠ Unfamiliar with local permit requirements

A legitimate local contractor pulls mechanical permits for replacements as required by local code. "We don't need a permit" is usually false.

// FAQ · Lehi

22 questions from Lehi homeowners.

References from Energy Star, ASHRAE, and the NATE board.

How much does AC repair cost in Lehi?+
Speakable ✓

AC repairs in Lehi typically run $150–$650 depending on the failed component. Capacitor replacements cost $180–$320, refrigerant recharges run $220–$650, and compressor work starts at $1,500. A diagnostic visit ($85–$150) is usually credited toward the repair when you authorize same-visit.

How fast can an HVAC contractor get to me?+
Speakable ✓

Most matched contractors in the Lehi network dispatch within 2–4 hours for standard calls and 30–90 minutes for 24/7 emergency. No-cool and no-heat calls are routed first. Rural suburbs may add 30 minutes to typical response.

Are all the contractors licensed and insured?+
Speakable ✓

Yes. Every HVAC contractor in the network is verified for state licensing, EPA 608 refrigerant-handling certification, and liability insurance on file with us. We re-verify annually and audit any pricing complaint within 48 hours.

What does it cost to replace an HVAC system in Lehi?+
Speakable ✓

A full 3-ton central system replacement in Lehi runs $5,500–$9,500 including outdoor unit, air handler, install, permit, haul-away, and warranty. Heat pumps run $7,200–$11,500. Federal tax credits and utility rebates may apply.

Should I repair or replace my AC?+
Speakable ✓

Rule of thumb: if your unit is 10+ years old and the repair quote exceeds 50% of a new system ($5,500+), replacement is usually cheaper long-term. A matched contractor can run the math on your specific unit with no pressure to replace.

Do you service commercial HVAC in Lehi?+
Speakable ✓

Light commercial yes — rooftop units (RTUs), split systems, mini-splits for offices, restaurants, and retail. For industrial, multi-story chillers, or large process cooling, our network includes specialist commercial contractors in the Lehi metro.

What HVAC brands do matched contractors service?+
Speakable ✓

Trane, Carrier, Lennox, Goodman, Rheem, York, American Standard, Bryant, Amana, Ruud, Daikin, Mitsubishi, LG, Fujitsu, Gree, and more. If it's residential or light commercial, a matched Lehi pro can handle it.

Can I request a specific contractor?+
Speakable ✓

Not directly — our matching algorithm picks the best fit based on location, availability, and your system type. You're free to decline a match and request another, and you can always call us on the phone if you want a different pro.

Do you offer financing for a new system?+
Speakable ✓

Matched contractors offer financing pass-through via Synchrony, GreenSky, and similar providers — typically 0% for 12–24 months with approved credit. We don't finance directly. Ask your matched pro for current promotions.

What's the difference between this and Angi or HomeAdvisor?+
Speakable ✓

Angi sells your info to multiple contractors simultaneously (your phone rings 6 times). We match one vetted contractor who actually called the pricing complaint process signed. You get one call, one quote, and the network has skin in the game.

Is the matching service free?+
Speakable ✓

Yes, the matching service is free for homeowners. Matched contractors pay us a referral fee only after you authorize work — it's in their interest to quote fairly and arrive on time. No credit card required to request a match.

What areas around Lehi do you serve?+
Speakable ✓

The entire Harris County metro: Lehi, Sugar Land, Katy, Pearland, The Woodlands, Cypress, Spring, Pasadena, League City, Humble, Friendswood, Clear Lake, Memorial, Montrose, River Oaks, West U, Bellaire, and surrounding ZIPs.

How often should I have my HVAC system serviced?+
Speakable ✓

Schedule two professional tune-ups per year: one pre-summer (April–May) for the AC side and one pre-winter (September–October) for heating. This schedule is recommended by the U.S. Department of Energy and catches refrigerant drift, electrical looseness, and duct leaks before they strand you.

What SEER2 rating should a new AC unit have?+
Speakable ✓

The federal minimum SEER2 in the Southern U.S. (including Lehi) is 14.3 as of 2023. Most homeowners should target SEER2 15–18 for the best return on investment. High-efficiency variable-speed systems hit SEER2 20–22 and qualify for federal tax credits up to $2,000.

Am I eligible for federal HVAC tax credits in 2026?+
Speakable ✓

Yes. The Inflation Reduction Act's 25C Energy Efficient Home Improvement Credit offers 30% back (up to $2,000) on qualifying heat pumps and up to $600 on high-efficiency AC systems. Your matched contractor provides the required AHRI-matched-system certificate for filing.

What are signs of a scam HVAC contractor?+
Speakable ✓

Major red flags: no state license on the truck, cash-only payment, quotes far below market (under $75 diagnostic), pressure to "fix it today" without a written quote, unwillingness to show insurance paperwork, or vague "special deals" with no matching invoice. Our vetted network screens for all of these.

How long should an HVAC system last?+
Speakable ✓

A properly-maintained central AC lasts 12–15 years; a gas furnace lasts 15–20; a heat pump lasts 10–15. Units that skip annual maintenance typically fail 3–5 years early. Location matters: coastal Lehi-area salt exposure can cut outdoor condenser life by 2–3 years.

Do I need a permit for HVAC replacement?+
Speakable ✓

Yes. Residential HVAC replacement in most Texas jurisdictions requires a mechanical permit filed by a licensed contractor. Your matched pro pulls the permit, handles inspection scheduling, and files the AHRI certificate — all included in the quoted install price, no extra fee.

What's the difference between R-410A and R-454B refrigerant?+
Speakable ✓

R-410A is the standard refrigerant used 2010–2024; R-454B is the EPA-mandated lower-GWP replacement phasing in on new equipment since 2025. Existing R-410A systems remain legal and serviceable, but expect refrigerant recharge costs to climb through 2027 as supply tightens.

Can I install a smart thermostat myself?+
Speakable ✓

Most modern smart thermostats (Nest, Ecobee, Honeywell T-series) are DIY-installable if your existing wiring includes a C-wire. If you only have R/W/Y wires, you'll need a C-wire adapter or a pro install. Budget $185–$420 for professional install with proper system compatibility check.

Is a heat pump or gas furnace better for Lehi?+
Speakable ✓

Heat pumps are increasingly cost-effective in the Lehi climate thanks to mild winters and rising gas prices. A modern cold-climate heat pump runs ~30% cheaper per season than gas in most Harris County homes, and qualifies for the full $2,000 federal 25C tax credit.

What's the best way to lower my monthly cooling bill?+
Speakable ✓

Top impact moves: (1) seal duct leaks — typical 18% bill reduction, (2) upgrade to a programmable or smart thermostat — 8–10% savings, (3) replace air filter monthly during peak season, (4) add attic insulation to R-38+ in Lehi, (5) shade the outdoor condenser without blocking airflow.

// Quick HowTo

AC died in Lehi? Do this first.

Turn the thermostat off

If the system is running but not cooling, switching it off prevents the outdoor compressor from cycling against a locked condition, which can cause further damage.

Check the breakers + filter

The two most common DIY-fixable causes are a tripped breaker (look at the 240V AC disconnect outside) and a filter so clogged it's frozen the evaporator coil. Both are free fixes.

Inspect the outdoor condenser

Is the fan spinning? Any visible refrigerant oil stains at the line set? Is the unit humming but not running? Note what you see — it speeds up the diagnostic.

Request a match

Call 1-877-877-6723 or submit the form. Tell us your ZIP, the symptom, your system's age, and your urgency. Median match time in Lehi is 90 seconds.

Confirm the quote before work starts

Every matched Lehi contractor will give you a written flat-rate quote before any work. If the price changes once they're on-site without a clear reason, call us back — we audit.

// HVAC glossary

Ten terms every Lehi homeowner should know.

Manual-J

Industry-standard heat-load calculation that sizes an HVAC system to a home's actual cooling/heating need based on insulation, orientation, window area, etc. Any installer who skips this and sizes by rule-of-thumb is likely over- or under-sizing your system.

SEER2 / HSPF2

2023+ efficiency ratings for cooling (SEER2) and heat pump heating (HSPF2). Minimum federal SEER2 in the South is 14.3. High-efficiency variable-speed systems hit SEER2 16–22.

EPA 608 Universal

Federally required certification to handle refrigerant. Any contractor touching the refrigerant circuit must hold it. We verify on file annually for every matched pro.

Refrigerant (R-410A / R-454B)

The working fluid in your AC. R-410A was the standard 2010–2024. R-454B is the lower-GWP replacement phasing in for new equipment since 2025.

Coil freeze-up

When the indoor evaporator coil ices over, usually from low airflow (dirty filter) or low refrigerant charge (leak). System will run but blow warm air.

Static pressure

The resistance air faces moving through the ducts. High static = bad airflow = comfort problems + shorter equipment life. Matched pros measure it during diagnostic, not eyeball it.

Condensate line

PVC pipe that drains the water your AC pulls from the air. When it clogs (algae, debris) it floods the drain pan — a top-3 summer service call in Lehi.

Ductless mini-split

Outdoor condenser + one or more indoor wall/ceiling units, no ductwork. Popular for Lehi home additions, garages, or converting non-ducted rooms.

RTU (Rooftop Unit)

Commercial packaged HVAC that sits on the roof of small- and mid-sized commercial buildings. Matched commercial contractors in Lehi handle service and replacement.

AFUE

Annual Fuel Utilization Efficiency — how much of the gas you burn actually heats your home vs. going up the flue. Minimum 80%; high-efficiency condensing furnaces hit 95–98%.
