75 Degree AC has been servicing commercial heating systems across Houston for businesses of every size. Our contractors work on rooftop units, package systems, commercial furnaces, boilers, unit heaters, and air handling units in offices, strip malls, restaurants, medical buildings, and warehouses.

We offer both one-time repairs and ongoing maintenance contracts for businesses that want scheduled service throughout the year. When a commercial system needs replacement, we present the options with honest recommendations based on the building’s heating load and operating schedule, not on which unit has the highest margin.

Our Complete Commercial Heating Services in Houston, TX
Commercial Heating Repair
When a commercial heating system fails, it affects everyone in the building. Our commercial heating repair service covers rooftop units, commercial furnaces, unit heaters, and air handling units. We diagnose the fault, explain the cause, and complete the repair with the building's operations in mind.
Commercial Furnace Service
Commercial furnaces operate under heavier demand than residential systems and require service matched to that workload. Our commercial furnace service includes burner inspection, heat exchanger checks, combustion analysis, gas pressure testing, and blower motor verification on every call.
Rooftop Unit Heating
Rooftop units are the most common heating and cooling systems on commercial buildings in Houston. Our rooftop unit heating service covers gas heating sections, economizer operation, damper actuators, and control boards. We service all major RTU brands and carry common replacement parts on the truck.
Commercial Maintenance
Scheduled maintenance prevents breakdowns during the heating season and extends the life of commercial equipment. Our commercial heating maintenance service includes seasonal tune-ups, filter replacement, combustion analysis, safety checks, and a written report after every visit. Maintenance contracts are available for buildings that want scheduled service on a set calendar.
Commercial Installation
When a commercial heating system reaches the end of its service life or a new building needs a heating solution, our commercial heating installation service covers equipment selection, load calculation, ductwork, gas and electrical connections, permits, and the city inspection. We size the system to the building's actual heating load.

Repair or Replace
The repair is completed with parts matched to the commercial system. When replacement makes more financial sense, our contractors present the options with clear pricing. Equipment is ordered and scheduled around the building's operations.
Test Under Full Load

How Commercial Heating Systems Differ From Residential in Houston
Commercial heating systems are built for larger spaces, higher airflow demands, and longer run times than residential equipment. A rooftop unit on a commercial building handles heating and cooling for an entire floor or zone, with ductwork that spans much greater distances than a typical home. Gas-fired unit heaters in warehouses and shops operate differently from furnaces, using direct combustion to heat open areas without ductwork at all.
Service requirements are different too. Commercial systems run harder and need more frequent maintenance to stay efficient. Filters clog faster in high-traffic buildings, burner assemblies see more wear, and rooftop units are exposed to Houston’s heat, humidity, and storms year-round. We understand those differences and bring the right tools, parts, and diagnostic approach to every commercial heating service call in Houston.

Frequently Asked Questions
Does 75 Degree AC Service Rooftop Heating Units on Commercial Buildings in Houston?
Yes. Rooftop units are the most common commercial heating system we service in Houston. Our contractors access, inspect, and repair RTU heating sections, including gas valves, ignition systems, heat exchangers, and control boards, on all major brands.
Can Commercial Heating Maintenance Be Scheduled Outside of Business Hours?
Yes. We offer evening, weekend, and after-hours scheduling for commercial heating maintenance. The goal is to keep service from disrupting your business operations or your tenants.
What Types of Commercial Buildings Does 75 Degree AC Service in Houston?
We service offices, retail stores, restaurants, warehouses, churches, schools, medical offices, strip malls, and multi-tenant buildings. Each building type has different equipment and heating demands, and our contractors have experience with all of them.
How Often Should a Commercial Heating System Be Inspected in Houston?
Twice per year is the standard recommendation for most commercial systems, once before the cooling season and once before the heating season. High-use buildings like restaurants and medical offices benefit from quarterly maintenance to catch wear before it causes a failure.
Does 75 Degree AC Offer Maintenance Contracts for Commercial Heating in Houston?
Yes. Our maintenance contracts include scheduled seasonal service, priority emergency dispatch, filter replacement, combustion analysis, and a written condition report after every visit. Contracts are customized to the building and the equipment.
What Is the Difference Between Commercial and Residential Heating Service?
Commercial systems are larger, more complex, and run under heavier demand than residential equipment. They require contractors with experience in rooftop units, multi-zone controls, building automation, and higher-capacity gas and electrical systems. Our contractors handle both but bring commercial-specific tools and diagnostic knowledge to every commercial job.
About Houston, TX
Houston, TX commercial properties span everything from high-rise offices in the Energy Corridor and Galleria area to strip malls, restaurants, and warehouses across the metro. Each building type puts different demands on its heating system, and the short but intense winter season means commercial equipment that sat idle for months has to perform reliably when the first cold front hits. Rooftop units on retail buildings along the I-10 and US-59 corridors are exposed to Houston’s heat, humidity, and wind for most of the year, which speeds up wear on heating components even when the system is only cooling.
In the medical district, downtown, and Westchase, commercial buildings with multi-zone systems and building automation controls need contractors who understand how commercial heating integrates with the rest of the HVAC system. A zone that is not heating properly can affect airflow balance across the entire building. Property managers in these areas need commercial heating service that works around tenant schedules and delivers results without disrupting daily operations.
