HVAC and Plumbing Services in Houston, TX

An air conditioner failure in a Houston summer is not something you work around. For households with elderly family members, young children, or anyone with a respiratory condition, a broken AC is a health issue that needs same day attention. Our team provides fast AC repair for Houston area homes, and we come prepared for the repairs that are most common in this climate.

What we see most often in Houston homes:

• Refrigerant leaks develop gradually as vibration and heat stress weaken connections over years of operation. When refrigerant drops, the system works harder, pulls more electricity, and still cannot properly cool your home. A low refrigerant system also stops dehumidifying effectively, which makes the indoor environment feel worse even when the temperature seems acceptable.
• Capacitor and contactor failures are among the most frequent repair calls we receive during Houston summers. These small electrical components degrade quickly under sustained heat exposure. When a capacitor fails, the compressor or fan motor makes a clicking or humming sound but will not start. It is usually a straightforward repair, but it needs to be done before the compressor itself overheats and sustains more serious damage.
• Frozen evaporator coils seem strange to mention in a city as hot as Houston, but they are common here. When airflow is restricted by a clogged filter, a closed vent, or collapsed ductwork, the evaporator coil drops below freezing even in 100 degree heat. The coil ices over, and when the ice melts, the unit starts blowing warm air and may drip water from the air handler into your ceiling or attic.
• Condenser coil buildup is underestimated by most homeowners. Cottonwood from trees, grass clippings, airborne dust, and debris from Houston storms all accumulate on the outdoor unit's coil. A significantly fouled condenser can reduce efficiency by 25 to 30 percent and cause the compressor to run hot.

If your AC stopped working or quit in the middle of the night, read our emergency AC repair guide and then call us.

If your system is 12 to 15 years old, you are likely spending significantly more each month on electricity than you would with a current system. Houston's demanding cooling season means HVAC equipment here hits the end of its practical lifespan faster than the national average simply because of how many hours it runs.

When it is time to replace, getting the sizing right matters more than most people realize. An oversized unit in a Houston home cools the space too quickly, shuts off before it removes enough moisture from the air, and leaves you with a home that feels damp and clammy even at the right temperature. An undersized unit runs nonstop on hot days and still cannot keep up. Neither situation is acceptable in a city where you will be living with that system for the next 15 years.

For Houston homeowners looking at maximum efficiency, the ION HVAC system is particularly well suited to this climate. Its variable speed compressor runs at lower speeds for longer periods rather than cycling on and off at full power. This approach removes substantially more moisture from the air than a standard single stage system, which is exactly what you want in a climate as humid as Houston's.

Day & Night ION System — Built for Houston

The ION system's variable speed compressor is uniquely effective in Houston's humidity. It runs longer at lower capacity, removing far more moisture from the air than a standard single-stage system — leaving your home feeling cooler at the same thermostat setting.

Houston winters are mild far more often than they are severe, but that is exactly the problem. Because heating season rarely comes with any urgency, furnaces here often go years without inspection. Then a cold front drops temperatures 40 degrees overnight, and systems that seemed fine in the spring suddenly fail when they are actually needed.

We provide heating repair, furnace repair, and same day furnace repair for Houston area homes throughout the heating season. If your heater will not turn off or your furnace will not turn on when you need it, we come out and diagnose it the same day.

The best time to catch heating problems is before Houston's first real cold front of the season, not during it. Read more about why heating maintenance directly saves money for Houston homeowners each winter.

Houston's humidity creates duct conditions that are fundamentally different from what you see in drier climates. Moisture infiltrates ductwork through small gaps and condensation, creating an environment where dust, mold spores, and biological material build up over years of operation. In many Houston homes, particularly older builds in areas like Meyerland, Bellaire, and Briargrove, ductwork has not been cleaned in over a decade.

When contaminants accumulate, you often notice it before you see it. An AC that smells like mildew, burning plastic, or chemical odors is frequently signaling a ductwork or evaporator coil problem rather than a compressor issue.

Our air duct cleaning service removes accumulated debris and restores proper airflow throughout the system. This directly improves indoor air quality and often improves efficiency because the air handler is no longer working against restricted lines.

Many newer West Houston and Energy Corridor area homes are two-story builds, and uneven temperatures between floors are one of the most consistent complaints we hear. The upstairs can run 8 to 10 degrees hotter than the ground floor on a hot August afternoon, and the typical thermostat only reads temperature at one location. We explain why two-story homes get hot spots and what actually fixes the problem — including when the fix is a zoning upgrade rather than just a bigger system.

In Houston, preventive maintenance is not a nice-to-have. A system running nearly year round needs to be inspected and serviced to have any realistic chance of reaching its expected lifespan. Without maintenance, small problems compound into expensive ones right when outdoor temperatures are at their worst and repair schedules are backed up for days.

Our spring tune-up covers refrigerant levels, condenser and evaporator coil cleaning, electrical component testing, drain line flushing, and a full assessment of anything approaching failure. It is the single most cost-effective thing a Houston homeowner can do to protect their HVAC investment.

If you're already noticing signs that your system needs a tune-up — higher utility bills, uneven cooling, shorter cycles or longer ones than normal — schedule before summer arrives.

For Houston homeowners who are away during the day, a programmable smart thermostat alone can cut cooling costs meaningfully by letting you set the home warmer during unoccupied hours and cooling it down before you arrive. We install and configure smart home and thermostat systems that match how you actually use your space, not just the default manufacturer settings.

Temper Mechanical serves offices, restaurants, medical offices, retail spaces, and light commercial buildings throughout the greater Houston area. Commercial HVAC service requires different expertise than residential work, particularly around load calculations, equipment selection, zoning, and maintaining uptime during business hours.
