Heating and air conditioning service built around Austin
Extended extreme heat, attic temperatures well above 140 degrees, and grid stress during heat waves are the norm. Our Austin teams are set up for exactly that: rapid response, flat-rate pricing quoted before work begins, and no surprise overtime charge for nights or weekends.
Local homeowners often run their system harder than the design intended, especially during March through November. That accelerates wear on contactors, capacitors and blower bearings.
Heating season here is December through February. A pre-season inspection catches cracked heat exchangers and failing igniters before the first real cold snap.

Austin78718 HVAC questions, answered
Do you handle ductless mini-split systems?
Yes. Ductless installations have grown quickly in Texas, particularly in older homes without existing ductwork. We service indoor heads, clean filters and drain lines, check line-set insulation and diagnose communication faults between heads and the outdoor unit.
Should I repair my system or replace it?
The usual rule of thumb: if the repair costs more than half the price of a replacement and the equipment is over ten years old, replacement generally wins. We will run that comparison with you on site and show you the maths — and if the honest answer is a $180 capacitor rather than a $9,000 system, that is the answer you get.
What does a new system cost in Austin?
A complete residential replacement in the 78718 area generally lands between $6,000 and $13,000 installed, depending on capacity, efficiency rating and how much ductwork has to be modified. We always perform a Manual J load calculation first, because an oversized unit costs more to buy and runs worse than a correctly sized one.
Do you service commercial and light commercial properties?
Yes. Around Austin we handle rooftop packaged units, split systems, VRF/VRV installations and building automation faults for offices, retail, restaurants and multi-tenant buildings, including after-hours scheduling so you are not disrupting trade.
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in Austin, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in Austin see most often — but a firm price needs eyes on the equipment. Any company that quotes a final number without seeing the unit is usually quoting low to get through the door.
