Dependable commercial HVAC repair, replacement, and maintenance for small and mid-sized businesses — plus the added peace of mind of one company that also handles your plumbing.
Serving small commercial properties up to 25 tons throughout North Dallas and Beaumont, TX — including churches, medical offices, retail stores, salons, and schools.
Commercial HVAC You Can Count On, From a Company You Already Trust
When your business’s heating or cooling system goes down, it’s not just an inconvenience — it affects your customers, your staff, and your bottom line. All Service Heating, Air & Plumbing has been keeping McKinney and North Dallas comfortable since 1986, and that same family-owned commitment to reliability now extends to small commercial properties.
We specialize in commercial HVAC systems up to 25 tons — the right fit for churches, medical and dental offices, retail stores, salons, schools, and other small commercial spaces. Our licensed, factory-trained technicians provide the repair, replacement, installation, and maintenance services you need to keep your building comfortable and your operations running without interruption.
And because we’re also a full-service plumbing company, we can support both your HVAC and plumbing systems under one roof — one point of contact, one trusted vendor, fewer vendors to manage.
Our Commercial HVAC Services
Commercial HVAC Repair Rooftop units, package units, and split systems don’t wait for a convenient time to break down. Our technicians respond quickly to diagnose and repair commercial HVAC equipment (up to 25 tons) so you can get back to business with minimal downtime.
Commercial HVAC Replacement & Installation When a repair no longer makes financial sense, we’ll help you evaluate replacement options sized correctly for your space, your equipment load, and your budget — with efficient systems designed to lower long-term operating costs.
Commercial HVAC Maintenance Preventive maintenance is the single best way to avoid costly breakdowns and extend the life of your equipment. Our commercial maintenance visits are built around a comprehensive multi-point inspection and tune-up process.
Quarterly Commercial Maintenance Plans Our quarterly maintenance plans are designed specifically for small commercial properties that can’t afford unplanned downtime. Each quarterly visit includes a full HVAC system inspection and tune-up — plus one plumbing maintenance visit per year with quarterly maintenance plan, so both of your building’s essential systems are looked after year-round.
One Trusted Vendor for HVAC and Plumbing
Facility managers and small business owners have enough to manage without juggling separate vendors for every building system. All Service Heating, Air & Plumbing is one of the few local companies that can handle both your commercial HVAC and plumbing needs — from a leaking water heater to a failing rooftop unit — with the same licensed, professional team.
Why that matters for your business:
- One call, not two. Skip the hassle of coordinating separate HVAC and plumbing contractors for routine maintenance or emergencies.
- Consistent scheduling. Your quarterly maintenance visit covers both systems, so you’re not managing multiple appointments throughout the year.
- One relationship, one invoice, one company that knows your building. Our technicians get to know your equipment and your property over time, which means faster diagnosis and fewer surprises.
- Fewer disruptions to your operations. Coordinated visits mean less back-and-forth scheduling around your business hours, patients, students, or customers.
Commercial HVAC for the Businesses That Make McKinney, North Dallas, and Beaumont, TX Run
We work with small commercial property owners and facility managers across a range of industries, including:
- Churches & Places of Worship — Reliable comfort for services, events, and gathering spaces, with scheduling that respects your calendar.
- Small Medical & Dental Offices — Temperature and air quality control that meets the needs of patients, staff, and sensitive equipment.
- Retail Businesses — Comfortable shopping environments that keep customers in your store longer.
- Salons & Spas — Precise climate control for treatment rooms and client comfort.
- Schools & Educational Facilities — Dependable systems that support safe, comfortable learning environments, with service scheduled around school hours.
If your business falls into one of these categories — or another small commercial use — and your HVAC system is 25 tons or under, we’d love to talk about how we can support your facility.
