What's included in a Commercial HVAC

We focus on light commercial, buildings with rooftop units, package units, and split systems up to about 25 tons. Here's what we cover.

Rooftop unit (RTU) service

Repair, replacement, and quarterly maintenance on packaged rooftop units from major brands: Trane, Carrier, Lennox, York, Daikin, Bryant.

Package & split systems

Light commercial split systems and package units for offices, retail, and small restaurants. Repair and full replacement.

Service contracts

Quarterly maintenance, priority response within agreed SLAs, no-overtime emergency dispatch, and a discount on parts and labor. Multi-unit pricing for property managers.

Emergency dispatch

24/7 dispatch for service contract customers. We treat business downtime as urgent, slow response is not an option when your tenants are leaving messages.

Featured project

50-ton AHU replacement at NASA's Neutral Buoyancy Laboratory.

Replaced an aging chilled-water air handler serving the NBL control and communications room, integrated into the building automation system, scheduled around an active astronaut training facility.

  • Access Security clearance

The NBL is one of NASA's most demanding training facilities, a 6.2-million-gallon pool where astronauts rehearse spacewalks against full-scale ISS mockups. The control and communications room overlooking the pool runs around the clock during training operations, so HVAC failure is not an option. We removed the failing 50-ton McQuay air handler, set the new Daikin unit, and integrated controls into the existing building automation system, all while working around an active training schedule with full security clearance for every tech on site.

Step 01

Site access and coordination

Every Clear the Air technician on site cleared NASA security in advance. Work was sequenced around the NBL's active astronaut training calendar, including coordinated overhead crane time with the facility's rigging crew.

Step 02

Old unit removal

The original McQuay chilled-water AHU was rigged out using NASA's overhead bridge crane. Hoses, electrical, controls, and chilled-water piping were isolated and capped before the lift to keep the rest of the building online.

Step 03

New equipment set

A new 50-ton Daikin air handler was staged on the high-bay floor, rigged, and hoisted into the mechanical mezzanine using the same bridge crane. The set went down in a single shift to minimize the window of conditioned-air loss to the control room.

Step 04

Install and BAS integration

New chilled-water piping, low-voltage controls, VFD, and ductwork insulation were installed and tied into the existing system. Final commissioning brought the unit online under the building automation system, giving the NBL's operations team full remote visibility and control.

Critical-environment HVAC, on a NASA schedule, with security clearance for every tech, this is the kind of light-commercial work we built our service contracts to handle.

How a visit works

Five steps. No surprises. Same on your first call as your fiftieth.

  1. Site walkthrough

    A senior tech walks the building, photographs every unit, records age, model, and condition. We deliver a written assessment.

  2. Service plan proposal

    A maintenance plan matched to your equipment age and usage. Quarterly visits, response SLAs, and reporting cadence, all in writing.

  3. Onboarding

    We set up service tickets, dispatch protocols, and reporting. You get a single point of contact who knows your buildings.

  4. Ongoing service

    Quarterly maintenance, repair tickets, and a documented service log so you have history when equipment needs replacement.

  5. Equipment replacement when needed

    When a unit reaches end-of-life, we propose options with side-by-side pricing and a project plan that minimizes business disruption.

What Pearland neighbors are saying

★★★★★

"We manage 14 retail properties in the South Houston corridor. Switched our HVAC service to Clear the Air two years ago. Single point of contact, monthly portfolio reports, and emergency response that actually shows up. Easy decision to expand the contract."

"Restaurant HVAC is brutal, kitchen heat, customer comfort, makeup air. Clear the Air services all three of our locations and our equipment uptime has gone from 'constant problems' to 'we don't think about it.' Their reports are thorough and the techs know our buildings."

★★★★★

"Rooftop unit died on a 100° Saturday at our office. They had a temporary spot cooler in within 4 hours and a full RTU replacement scheduled for the following weekend. That's the response time we needed. Real partnership."

Frequently asked

Do you do service contracts for property managers?

Yes. We offer multi-unit and multi-property service contracts with consolidated billing, single-point-of-contact dispatch, documented service histories, and SLAs that fit commercial property management. Pricing is volume-based.

What size buildings do you service?

Light commercial, typically buildings with HVAC up to about 25 tons total, served by rooftop units, package units, or light commercial splits. Office buildings, retail centers, restaurants, small industrial, and multi-tenant properties. For larger industrial or chiller systems we partner with specialty contractors.

How fast is your emergency response?

For service contract customers, we commit to written SLAs, typically same-day for non-critical and within 4 hours for full-outage situations. For non-contract customers we serve in the order calls come in, but we still prioritize commercial outages over residential when we can.

Do you handle restaurant ventilation and makeup air?

Yes. Restaurant HVAC has unique demands: kitchen exhaust hoods, makeup air units, dining-area comfort. We service the comfort side and partner with kitchen-specialty vendors when hood cleaning or fire-suppression certifications are required.

Can you replace rooftop units without disrupting our business?

Yes. We schedule rooftop unit replacements for after-hours, weekends, or off-peak windows when needed. Crane work is coordinated and announced. Most replacements can be done in a day with minimal tenant disruption.

Do you provide service reports?

Yes. Every visit gets a written service report with photos, measurements, parts replaced, and recommendations. Property managers get monthly or quarterly portfolio summaries, what was serviced, what's borderline, what to plan for.

Do you offer 24/7 emergency response?

Yes for service contract customers. After-hours dispatch is real, not a recording, and we dispatch from our local fleet, not a national call center.

Can you help with energy efficiency upgrades?

Yes. We do efficiency assessments, equipment age, run-time analysis, controls evaluation, and propose phased upgrades with payback math. CenterPoint Energy commercial rebates and federal tax incentives are factored into proposals when applicable.

Do you do critical-environment or government-facility work?

Yes. Our largest case study is a 50-ton chilled-water air-handler replacement at NASA's Neutral Buoyancy Laboratory at Johnson Space Center, the astronaut training pool. Every tech on site held NASA security clearance and the install was sequenced around an active astronaut training calendar. We do similar work for medical buildings, data closets, control rooms, and other facilities where downtime is not an option.
