Commercial HVAC & Refrigeration Maintenance Agreements

Most of the emergency calls we take in July were visible in March: a condenser coil packed with cottonwood, a belt glazed and slipping, a compressor pulling amps above nameplate, a walk-in gasket that had been leaking humid air into the box all spring. A quarterly maintenance agreement is how a building owner or restaurant operator stops paying for those in the middle of a heat wave.

TechBridge Pacific HVAC Corp offers three commercial plans, priced by the number of rooftop units and whether make-up air and exhaust fans are included. We are commercial-only, based in Melissa, TX, licensed under TDLR TACLA 00151786R, and we serve McKinney, Frisco, Plano, Allen, and the surrounding North Dallas area. Call (469) 609-6204 or request a quote.

What “Priority Dispatch” Means

We are a two-technician company, and we do not overbook. Plan customers go to the front of the schedule when they call with a failure, ahead of first-time callers. The published commitment is dispatch within 24 hours, with no diagnostic fee on the visit and 10 percent off the repair. After-hours calls for plan customers are billed at the after-hours rates on the pricing page.

What Happens at Each Quarterly Visit

Every visit produces a written report: measured values, anything trending the wrong way, and any repair we recommend, with a price. Nothing is repaired without your approval beyond the filters and belts that are already included.

Spring (March to April): cooling readiness

• Condenser coils cleaned; evaporator coils inspected and cleaned as needed
• Refrigerant charge verified by superheat and subcooling at operating load
• Compressor and fan motor amp draw logged against nameplate; megohm test on any compressor trending high
• Contactors, capacitors, and wiring terminations checked
• Condensate drains cleared, pans and overflow switches tested
• Economizer dampers, actuators, and sensors verified
• Filters and belts replaced; pulleys aligned
• Thermostat calibration and schedule review

Summer (June to July): peak-load check

• Delta-T across each evaporator under load
• Head pressure and condenser performance in high ambient; coil recleaned if needed
• Amp draw recheck on compressors and condenser fans
• Condensate drains recleared (the number one summer service call)
• Filters replaced; belt tension rechecked

Fall (September to October): heating readiness

• Gas heat: igniter, flame sensor, gas valve, inducer, pressure switches, manifold pressure, temperature rise
• Heat exchanger inspection
• Heat pump: reversing valve and defrost control operation
• Economizer set for shoulder-season free cooling
• Filters and belts replaced

Winter (December to January): mid-season check

• Heat operation verified under load; flame signal and temperature rise rechecked
• Low-ambient controls on refrigeration condensing units
• Make-up air burner and discharge temperature (if on plan)
• Filters replaced; overall electrical and safety inspection

Rooftop Unit Checklist (every visit)

• Filters replaced
• Belts inspected or replaced, pulleys aligned, bearings lubricated
• Condenser coil condition and cleaning
• Evaporator coil inspection
• Superheat, subcooling, and delta-T recorded
• Compressor and fan amp draw recorded
• Contactors, capacitors, relays, and terminations
• Condensate drain and pan
• Economizer operation
• Thermostat and controls
• Seasonal heat inspection (fall and winter)

Make-Up Air and Exhaust Fan Checklist (Medium and Large plans)

• Exhaust fan belt, pulley, motor amp draw, bearings, hinge kit, grease containment
• MUA intake filters, supply fan, belt, damper actuator
• MUA burner, ignition, flame sensor, gas pressure, discharge temperature
• Hood-to-MUA interlock verified
• Airflow logged to catch drift before it becomes a negative-pressure complaint

More on how ventilation and rooftop units interact on our commercial kitchen ventilation page.

Refrigeration Checklist (add-on)

• Condenser coil cleaned, condenser fan motor checked
• Evaporator coil inspection, defrost cycle verified (timer or controller, termination, heaters)
• Superheat and subcooling logged per circuit
• Compressor amp draw and megohm trend
• Door gaskets, hinges, closers, and door heaters
• Drain lines and pan heaters
• Controller setpoints and temperature alarms
• Ice machines: water-side scale, float or sensor operation, harvest cycle

What a Plan Does Not Cover

Plans cover the labor and materials for the quarterly visit, filters, and belts. Repairs outside the visit are billed separately at the plan discount. Refrigerant, major components, and equipment replacement are quoted before work begins. We would rather be clear about that on this page than surprise you on an invoice.

Who These Plans Fit

• Restaurants with two to four RTUs, a hood and MUA, and refrigeration: usually Medium plus a refrigeration add-on. See restaurant HVAC.
• Retail and office tenants responsible for their own HVAC under the lease: usually Small or Medium.
• Property managers with multi-tenant plazas: Large, or a custom quote across buildings, with per-unit reporting for tenant billing.
• Grocers, convenience stores, and distributors with refrigeration as the priority: refrigeration-led plan quoted individually.

Why TechBridge Pacific

Two technicians, commercial-only. The technician who did your spring visit is the one who shows up in July, with last quarter’s readings on the truck. EPA 608 certified, factory training from LG and Daikin (certifications), TDLR TACLA 00151786R. We measure rather than eyeball, and the numbers are in your report.

Service Area

McKinney, Allen, Melissa, Anna, Prosper, Celina, Frisco, Plano, Richardson, and Dallas.

Frequently Asked Questions

Is there a contract term?

No. Plans bill monthly, renew automatically, and can be cancelled at any time.

What counts as a “unit”?

Each packaged rooftop unit or split system counts as one unit. Make-up air units and exhaust fans are included in the Medium and Large tiers as listed. Refrigeration equipment is added separately.

Do plan customers pay a diagnostic fee?

No. The diagnostic fee is waived for plan customers, and repairs are discounted 10 percent.

How fast do you respond if a plan customer has a failure?

Plan customers receive priority dispatch, with a published commitment of 24 hours and same-day response in most cases. Refrigeration failures with product at risk are treated as the top priority.

Are filters really included?

Yes, standard pleated filters and belts are included at every quarterly visit. Specialty filters (high-MERV, odd sizes) are quoted.

Can you schedule visits before we open or after we close?

Yes. Restaurants in particular usually prefer early-morning visits, and we plan the schedule around that.

Do you provide documentation for our landlord or insurer?

Yes. Every visit produces a written report with measured values, which most landlords and insurers accept as proof of maintenance.

Can you cover buildings in more than one city?

Yes, across our service area from Anna and Melissa down to Richardson and Dallas. Multi-site customers get a single point of contact and consolidated reporting.
