Call (866) 427-9264 Jump to AC problems

Cooling

Air conditioning

The core of the business. Cooling season here effectively runs April through October, and these are the jobs that fill it.

AC repair

Diagnosis and repair of residential cooling systems. Start here if the system is running but the house is not getting cooler.

AC replacement and installation

Load sizing, equipment selection, permits and installation. Includes what the R-410A phase-down means for pricing.

Emergency AC repair

24/7 service for a total cooling loss. What counts as an emergency and what can safely wait until morning.

HVAC maintenance

What a real maintenance visit covers, and why drain lines and coils matter more in a humid climate.

Symptoms

HVAC problems

If you know what the system is doing but not why, start with the symptom rather than the service.

Each of these pages explains the likely causes, what is safe for a homeowner to check, and the point at which guessing costs more than diagnosing.

Components

Parts and repairs

Pages for the specific components that fail. Useful if a technician has already named the part and you want to understand what you are being quoted for.

Wear parts

Capacitors, contactors and blower motors fail from accumulated runtime. In a climate with around 102 days a year above 90°F, that arrives sooner than the equipment’s design life suggests.

Sealed system parts

Compressors, coils and line sets sit inside the refrigerant circuit. Repairs here are longer, more expensive, and much more likely to trigger a replace-instead conversation.

Condensate parts

Drain lines, drain pans and float switches exist because a coil pulls water out of humid air all day. They are also the most common source of ceiling damage.

Comfort and airflow

When the equipment is fine and the house still is not comfortable

A correctly sized, correctly charged system can still leave rooms unusable. When that happens the problem is almost always distribution rather than capacity.

Ductwork

Leak testing, sealing, resizing, replacement and rerouting. Leaky attic ducts dump conditioned air into a space that can run well over 120°F in summer.

Zoning and airflow

Dampers, zoning systems and air balancing for houses where one thermostat cannot satisfy two floors.

Upstairs will not cool

The single most common comfort complaint in two-storey Fort Bend County houses, and what actually fixes it.

Indoor air quality

Filtration, humidity control and ventilation. Relevant in a metro that averages around 75% relative humidity.

Equipment and specialities

Other systems we work on

Ductless mini-splits

For garage conversions, additions, sunrooms, offices and any space the main system was never sized to serve.

Heating and furnaces

Gas furnaces and heat pumps. Lightly used most winters, then heavily depended on during a freeze event.

HVAC for remodels and new construction

Where the HVAC and construction sides of the company overlap. Additions, conversions, duct relocation and new zones.

Commercial HVAC

Rooftop units, buildouts and light commercial systems for offices, retail and warehouse space.

Based on Murphy Road in StaffordNot a call centre routing your job to whoever is free. The office sits between Sugar Land, Missouri City and the Southwest Freeway.

24/7 emergency HVAC serviceCooling failures do not wait for business hours. Office hours are Monday to Saturday, 9am to 6pm.

HVAC, construction and electrical under one roofWhen a cooling problem turns out to be a duct route, a return opening or a circuit, it does not become somebody else’s job.

You get a phone call, not a formThere is no contact form on this site on purpose. Describe the symptom, get an answer, book the visit.

Before you call anyone

Two things worth checking on every HVAC company you consider

First, the licence. Air conditioning and refrigeration contractors in Texas are licensed by the Texas Department of Licensing and Regulation under its ACR programme. Ask for the licence number and check it against the TDLR licence search. That applies to this company as much as to anyone else you are comparing.

Second, the permit. A full system changeout in Stafford, Sugar Land or Missouri City requires a mechanical permit, and pulling it is the contractor’s job rather than yours. A quote that is unusually cheap because nobody intends to permit or inspect the work is not actually cheaper. It becomes your problem when you sell the house.

Neither of these is a sales pitch. They are the two questions that separate a real contractor from a truck with a magnet on the door, and they take about ninety seconds to ask.

What to have ready when you call

Brand and rough age of the system, from the label on the outdoor unit
What the thermostat is set to and what it reads
Whether the outdoor unit is running, humming or silent
Whether the problem is the whole house or specific rooms

None of this is required. It just shortens the conversation.

Where we work

Service areas

Coverage is strongest close to the Stafford office and thins out with distance. These four markets are where most jobs happen.

Stafford

The home market. Mixed housing ages, a large commercial corridor, and the office is minutes from most of the city.

Sugar Land

First Colony, Sugar Creek, New Territory, Greatwood, Telfair and Riverstone. Mostly two-storey homes with attic air handlers.

Missouri City

Quail Valley through Sienna. A wide spread of build dates, from late-sixties construction to current builds.

Southwest Houston

Sharpstown, Westbury, Meyerland, Braeswood and Fondren. Mid-century homes where the duct system is often the real problem.

Questions about HVAC service

What is the difference between AC repair and HVAC service?

In practice the words get used interchangeably. HVAC covers heating, ventilation and air conditioning as a whole system. In this climate the overwhelming majority of calls are cooling, so most people say AC repair and mean the same thing. The distinction matters when the problem turns out to be ventilation rather than the equipment itself, which is more common than it sounds.

Do you service systems you did not install?

Yes. Most service calls are on equipment installed by somebody else, often years earlier. Knowing the brand and rough age of the system helps when you call, and both are usually printed on a label on the outdoor unit.

Do you handle commercial buildings as well as houses?

Yes. Haswani does commercial buildouts alongside residential work. Commercial HVAC has different equipment, different access and different scheduling constraints, so it has its own page.

Is there a maintenance plan?

Ask when you call. Rather than publish plan tiers and pricing that may not match what is currently offered, the honest thing is to have that conversation directly. What maintenance actually involves is set out on the maintenance page.

Still not sure what you are dealing with? A technician can tell you in one visit.

Not sure which of these you need?

Describe what the system is doing and someone will tell you which category it falls into, including when the answer is that it can wait.
