Our Process — From First Call to Commissioning Printout

Every HVAC job in Bluffdale follows the same eight-stage workflow whether it’s a $185 flame sensor cleaning at 2 a.m. or a $22,000 Mitsubishi Hyper-Heat conversion on a Redwood Road ranch. The stages don’t change; the depth at each stage scales with the project. This page walks you through what actually happens between when you dial (801) 610-6528 and when Elena Marquez hands you the commissioning printout with the AHRI Certified Reference Number stapled to the top. Skipping stages is what produces the $12,800 furnace quotes when the actual failure is a $95 hot surface igniter. Not skipping stages is what keeps our first-visit repair rate above 90% and our second-opinion save rate high enough to be its own page.

Stage 1: Initial Contact and Intake

Most calls come in three ways: emergency dispatch at (801) 610-6528, web form on this site, or text to the office line during business hours. Rachel Kimball or a member of her team handles intake — not an offshore answering service, not a chatbot. Intake captures:

• Your name, service address, and best callback number
• Nature of the issue: no heat, no cool, strange noise, high energy bill, planning a replacement, indoor air quality concern, new construction consultation
• Existing equipment make, model, and approximate age if known (nameplate photos help)
• Any safety concerns: CO alarm sounding, gas smell, water leak, iced-over condenser
• Household context relevant to IAQ: asthma or respiratory conditions, wood-burning fireplace use, humidification preferences

Safety concerns get triaged immediately. If your CO alarm is sounding, you get the same instruction we’d give a family member: evacuate, ventilate, call Dominion Energy at 1-800-323-5517 for a gas emergency, then call us for the follow-up diagnostic once the immediate hazard is cleared.

Stage 2: Dispatch and Arrival Window

Business-hour service calls inside Bluffdale get a 2-hour arrival window with a 30-minute-out courtesy call from the technician. Emergency calls get in-vehicle response inside 45 minutes for Bluffdale city limits, under 90 minutes overnight, and under 25 minutes drive-time for adjacent cities Riverton, Draper, Herriman, Lehi, and South Jordan in normal traffic. The dispatched technician text-messages a photo of their van and license plate before pulling into your driveway so you know who to expect.

Stage 3: Diagnosis with the Meter

Every service call starts with measurement, not conversation. The technician walks the equipment first, then attaches the diagnostic tools before making a repair recommendation.

On Furnaces

• Bacharach InsightPlus combustion analyzer readings: CO air-free (target under 100 ppm), O2 percentage, stack temperature against manufacturer spec
• Manifold gas pressure verification on Dominion Energy delivery (7″ WC nominal, 14″ WC max)
• Static pressure across the air handler (residential target under 0.5″ WC, ECM variable-speed under 0.8″ WC)
• Flame rectification current in microamps (target above 2.5 µA for reliable flame sensing)
• Inducer motor amperage compared to nameplate FLA
• Borescope inspection of primary and secondary heat exchangers if a crack is suspected

On AC and Heat Pump Systems

• Superheat and subcooling readings compared to manufacturer target charge tables
• Capacitor microfarad reading against nameplate rating (a 35 µF rated capacitor reading 8 µF is a different problem than one reading 32 µF — both look like no-start)
• Contactor voltage drop and pull-in verification
• Fan and compressor amperage against nameplate FLA
• Fluke Ti32 thermal imager scan of the evaporator, condenser, and refrigerant lines to locate flow restrictions or undercharge without invasive teardown
• Electronic refrigerant leak detection and UV dye follow-up on suspected charge loss

Stage 4: Documented Recommendation and Written Estimate

The diagnostic data determines the recommendation. Every recommendation ships with:

• Photos of the failed component and any adjacent conditions
• Meter readings that justify the diagnosis
• Written estimate with line items: equipment cost (make, model, AHRI Certified Reference Number if applicable), labor hours at current shop rate, permit fees for the relevant jurisdiction, refrigerant by the pound, any electrical or venting modifications, warranty registration cost
• Financing options if the total warrants it, with monthly payment calculations for each partner and term
• A repair-or-replace comparison when the failed component is on equipment near end-of-life

No verbal estimates that turn into invoiced surprises. No package pricing that hides margin. If you want time to think, the estimate is valid for 30 days.

Stage 5: ACCA Manual J Load Calculation (New Installs Only)

New AC, furnace, heat pump, and boiler installations start with an ACCA Manual J load calculation on site. This is where tonnage-by-rule-of-thumb goes wrong most often. A 1985 Redwood Road ranch with original single-pane aluminum windows and R-11 attic insulation might carry a 58,000 BTU/hr design heating load on 1,600 square feet. A 2022 Independence at the Point build with R-49 attic and triple-pane fiberglass windows on the same square footage might carry 26,000 BTU/hr. The load calc captures:

• Total conditioned square footage and volume (including ceiling height for cathedral spaces)
• Window count, orientation, glazing type, and framing R-value
• Wall assembly R-value including sheathing, cavity insulation, and continuous exterior insulation on post-2015 builds
• Attic and floor insulation R-values
• Air infiltration estimate (blower-door tested where available on post-2015 tight-shell homes)
• Occupancy heat gains and equipment loads
• Elevation correction (Bluffdale valley floor 4,436 ft; Point of the Mountain ridgeline to 4,700 ft; Suncrest and Draper foothills to 5,300 ft)
• Climate Zone 5B design temperatures: 9°F ASHRAE 99% winter, 96°F dry bulb / 62°F wet bulb ASHRAE 1% summer

Manual S equipment selection follows the load calc. Manual D duct verification follows equipment selection if the existing duct system is staying. All three deliverables ship with the written estimate.

Stage 6: Permit Filing and Scheduling

Every installation requires a mechanical permit through the relevant jurisdiction. Bluffdale City Building Services for Bluffdale addresses (Independence at the Point, Spring View Farms, Bluffdale Heights, and all other Bluffdale neighborhoods). Riverton City Building Department for Riverton addresses. Draper City Building Department for Draper. Herriman City. South Jordan Building Services. Utah County Building Department for Lehi and southern Bluffdale portions.

Rachel Kimball files the permit application within one business day of contract signing. Permit fees are itemized on the estimate. Installation is scheduled to begin no earlier than the permit issue date — typically 3–5 business days for standard mechanical permits, longer for gas line installations that require Dominion Energy notification.

Stage 7: Installation Execution

Installations are led by Foreman Elena Marquez and her install crew. Standard install day sequence:

1. Site protection. Floor coverings from the driveway to the equipment location. Corner guards on interior wall passages. Drop cloths under any work area with potential debris.
2. Existing equipment removal. Refrigerant recovery under EPA Section 608 procedures if applicable. Gas shut-off and cap. Electrical disconnect. Careful demolition to avoid concealed damage to structural or plumbing.
3. New equipment set. Furnace or air handler placed on a level pad or hanging bracket per manufacturer spec. Outdoor condenser or heat pump set on a mini-split pad elevated for snow clearance and drain-line ice protection.
4. Line-set, gas, condensate, electrical rough-in. Line-set brazed under nitrogen sweep to prevent internal oxidation. Gas piping tested to Utah code (typically 60 PSI for 15 minutes with a soap-bubble check at every joint). Condensate lines pitched at 1/8″ per foot minimum, with secondary drain pan and float switch on any horizontal air handler over a finished space.
5. Duct modifications if needed. Manual D-verified duct rebuilds happen at this stage. Static pressure verified before charging refrigerant or firing the burner.
6. Refrigerant charge. Deep evacuation on R-454B systems (target: 500 microns held for 15 minutes). Nitrogen pressure test at 300 PSI. Charge weighed in on a digital scale to manufacturer spec, then verified by superheat and subcooling at target ambient.
7. Combustion commissioning on gas systems. First fire under supervision. Combustion analyzer readings verified against manufacturer target (target under 100 ppm CO air-free). Elevation derate applied and verified.

Stage 8: Commissioning, Documentation, and Warranty Registration

The install isn’t complete until the commissioning report is generated and filed. Every install ends with:

• Commissioning printout covering combustion analysis, static pressure, refrigerant charge verification, motor amperages, and setpoint verification — delivered to you and filed in the job record
• Manufacturer warranty registration filed within 60 days by Rachel Kimball for Carrier, Trane, Lennox, Rheem, Bryant, Goodman, American Standard, Mitsubishi Electric, Daikin, or Bosch systems — the registration window that activates the full 10-year parts warranty instead of the default 5-year unregistered coverage
• Rocky Mountain Power Wattsmart and Dominion Energy ThermWise rebate applications filed on qualifying installations, with confirmation numbers forwarded to you
• Federal IRA Section 25C credit documentation shipped to you for filing with your CPA or tax software (AHRI Certified Reference Number, installation invoice, ENERGY STAR label if applicable)
• Bluffdale City (or relevant jurisdiction) building department final inspection scheduled — typically within 5 business days of install completion. Homeowner presence or accessible property required for the inspector.
• Job file archived in our system for 10 years, matching Utah’s statute of limitations on construction defect claims (Utah Code § 78B-2-225) and available on request if a warranty claim or resale disclosure question arises later

What Happens Next

Every new install customer gets a 30-day check-in call from Rachel Kimball to confirm the system is running as expected and answer any operating questions. At 12 months we send a maintenance reminder. Comfort Club members ($189/year) get two visits per year automatically scheduled — spring AC service in April or May before summer heat, fall furnace service in September or October before PCAPS inversion season begins. Non-member service calls are available on demand at published rates.

Frequently Asked Questions

How long does the full process take from first call to installed system?

For a straightforward furnace or AC replacement with existing venting and ductwork in serviceable condition, typically 7–14 days from first call to commissioning. Day 1: initial contact and dispatch for in-home consultation. Day 2–3: written estimate delivered with Manual J load calc. Days 3–5: contract signing and permit filing. Days 6–10: permit issue and installation scheduling. Day 10–14: installation and commissioning. Full heat pump conversions with electrical service upgrades run 3–4 weeks. Emergency service calls compress the timeline dramatically — no-heat calls typically produce diagnosis and repair inside the same visit.

Why does every new install require an ACCA Manual J load calculation?

Because tonnage-by-rule-of-thumb gets Bluffdale wrong roughly half the time. A 1985 Redwood Road ranch with original single-pane aluminum windows and R-11 attic insulation carries a completely different design load than a 2022 Independence at the Point build with R-49 attic and triple-pane fiberglass windows on the same square footage. The Manual J captures window count and orientation, wall and attic R-values, air infiltration, occupancy heat gains, elevation correction (Bluffdale valley floor 4,436 ft), and Climate Zone 5B design temperatures (9°F ASHRAE 99% winter, 96°F ASHRAE 1% summer). The load calc drives Manual S equipment selection and Manual D duct verification. All three deliverables ship with the written estimate so you can see the reasoning behind the size we specified.

Do you handle permit filing and building department inspection?

Yes, on every installation. Rachel Kimball files the mechanical permit application within one business day of contract signing through the relevant jurisdiction: Bluffdale City Building Services for Bluffdale addresses, Riverton City for Riverton, Draper City Building Department for Draper, Herriman City, South Jordan Building Services, or the Utah County Building Department for Lehi and southern Bluffdale portions. Permit fees are itemized on the written estimate. Installation is scheduled to begin no earlier than the permit issue date. Final inspection typically schedules within 5 business days of install completion, and we coordinate directly with the inspector so you don’t have to.

What’s the difference between a diagnostic visit and a commissioning visit?

A diagnostic visit isolates the cause of a service failure using meter readings, borescope photos, thermal imager scans, and combustion analysis. A commissioning visit verifies that a new installation is running to manufacturer spec at the actual operating conditions of your home — combustion analysis on gas systems, static pressure across the air handler, refrigerant charge verification by superheat and subcooling, motor amperage against nameplate FLA, setpoint verification, and safety-limit function check. Diagnostic reports go with the repair recommendation. Commissioning reports go with the manufacturer warranty registration and the job file archived for 10 years.

Do you file utility rebate applications and federal tax credit documentation?

Yes. Rocky Mountain Power Wattsmart and Dominion Energy ThermWise rebate applications file through our office on qualifying installations, with confirmation numbers forwarded to you. Federal IRA Section 25C tax credit documentation (AHRI Certified Reference Number, installation invoice, ENERGY STAR label if applicable) ships to you for filing on IRS Form 5695 with your annual tax return — the actual credit gets filed by your CPA or through your tax software. Utah’s HOMES and HEAR rebate applications require additional measured energy savings documentation and file through the Utah Office of Energy Development on a separate application path.
