Heating and air conditioning service built around Houston
Extended extreme heat, attic temperatures well above 140 degrees, and grid stress during heat waves are the norm. Our Houston 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.
Around Houston, condensate drainage is a recurring fault. Blocked drains and failed float switches cause more water damage claims here than actual refrigerant failures do.
Because Texas runs high-capacity split air conditioning with gas or electric heat, the transition between seasons is when we see the most emergency calls — equipment that sat unused for months.

Houston77070 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.
What causes water to leak from the indoor unit?
Almost always a blocked condensate drain line, a failed drain pan float switch, or a frozen coil melting faster than the pan can handle. In Houston we see algae and dust clogging drain lines constantly during March through November. It is a fast fix but ignoring it ends in ceiling damage.
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 Houston, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
Do you charge extra for nights, weekends or holidays?
No. Our pricing in Texas is the same at 2am on a holiday as it is at 2pm on a Tuesday. Emergency calls are dispatched the same way as scheduled calls and carry no overtime premium.
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.
Is my system low on refrigerant, or is it leaking?
Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.
