We service and repair most major HVAC and heating brands found in Hill Country homes, including Coleman, Bryant, Fujitsu, Rheem, Rinnai, Navien, Weil-McLain, Williams, and Buderus — along with the equipment most homeowners inherited from whoever owned the house before them.

Why Brand Coverage Matters

Most homeowners did not choose their HVAC system. It came with the house, installed by a builder or a previous owner, and it is whatever it is.

A company that only services the brands it sells is not much use in that situation. You end up calling three contractors to find one who will work on a fifteen-year-old unit, usually while the house is uncomfortable.

Working across manufacturers also builds a kind of knowledge you cannot get otherwise. You learn which models have known failure points, which control boards are unreliable, and which units are worth repairing at year twelve versus which are not. That perspective is difficult to develop inside a single-brand shop.

Heating and Boiler Equipment

Several of those names — Weil-McLain, Buderus, Williams — are heating specialists, and a few are boiler manufacturers. Boilers and hydronic systems are less common here than in colder regions, but Hill Country homes do have them, particularly older and custom properties.

They require genuinely different expertise from forced-air equipment. Combustion, water chemistry, circulation, expansion, and controls all behave differently, and a technician who only knows furnaces is not equipped for them.

Wall furnaces and space heating equipment from Williams show up in older homes and additions as well, and they carry their own venting and safety requirements.

Tankless and Water Heating Brands

Rinnai and Navien are tankless water heater manufacturers, and Rheem builds both HVAC and water heating equipment. That overlap is one of the practical benefits of a company running both trades.

A tankless water heater sits squarely between the trades — it is a plumbing appliance with a gas burner and a venting system. Diagnosing one requires understanding combustion, gas supply capacity, and water chemistry at the same time. We handle those units without subcontracting.

Ductless Systems

Fujitsu is a major manufacturer of ductless equipment, and mini splits require a different diagnostic approach from central systems. Inverter-driven compressors, communicating controls, and error-code-based fault reporting mean the old methods do not apply.

These systems are increasingly common here for garage conversions, additions, shops, and rooms that central ductwork never served properly.

What Actually Determines Whether a System Lasts

Homeowners spend a great deal of energy comparing brands, and the truth is less satisfying: installation quality and maintenance matter more than the badge.

A premium system that is oversized, connected to leaking ducts, and never serviced will underperform a mid-tier system that was sized correctly and maintained. We have replaced plenty of expensive equipment that failed early for exactly those reasons.

Correct sizing comes from a load calculation. Correct airflow comes from ducts that were designed for the equipment. Longevity comes from service. None of that is on the nameplate.

Repairing What You Have

Our default is to repair a system that has life left in it. Parts availability varies by brand and age, and we are straight about it — some older units have control boards that are simply no longer manufactured, and at that point replacement is the honest answer rather than a hunt for salvage parts.

Where a repair makes sense, we make it. A working system you already own is almost always better value than a new one.

Service Across Both Trades

Whether it is AC repair, furnace repair, or a water heating issue, one company covers it. Regular Care Club maintenance is what keeps any brand running to its potential.

We serve Fredericksburg, Kerrville, Boerne, Comfort, Mason, and the surrounding Hill Country. To have your system diagnosed, contact 72 Degrees or call (830) 468-5316.
