Houston HVAC FAQs — Your Heating & Cooling Questions Answered

The most common causes are low refrigerant (from a leak), a dirty condenser coil, a failing capacitor, or a malfunctioning compressor. In Houston's heat, this needs immediate attention. Call Bayou City for same-day diagnosis.

Most AC repairs in Houston range from $150 to $900. Common repairs like capacitor replacement ($150–$300) and refrigerant recharge ($250–$500) are on the lower end. Compressor replacement can range from $800–$2,500. We always provide upfront quotes before starting work.

Our goal is a technician at your door within 60 minutes for emergencies across most of Greater Houston. We're available 24/7, including holidays.

This is often caused by a dirty evaporator coil, low refrigerant, a frozen coil, undersized equipment, or ductwork leaks. Our technicians will identify the root cause and fix it properly.

It depends on the sound. Gentle humming is normal. Banging, clanking, or grinding can indicate a failing component and running the system could cause further damage. Turn it off and call us.

Musty smells almost always indicate mold or mildew growth in your evaporator coil, drain pan, or ductwork — extremely common in Houston's humid climate. A UV light system and coil cleaning can permanently resolve this.

Check your thermostat settings and circuit breaker first. If those are fine, call us immediately at (713) 880-1955. In extreme Houston heat, this is a health emergency — especially for elderly or young family members.

In Houston's demanding climate, most central AC systems last 12–15 years. The extreme heat and long cooling seasons accelerate wear compared to cooler climates. Proper maintenance can extend this to 18–20 years.

New AC systems in Houston typically range from $3,500 to $10,000+ depending on system size (tonnage), efficiency rating (SEER), brand, and installation complexity. We offer free in-home estimates and financing options.

Texas building codes require a minimum of 15 SEER for new installations. We recommend 18–22 SEER for Houston homes for maximum energy savings. Higher SEER ratings pay back quickly given Houston's long cooling season.

System sizing depends on square footage, ceiling height, insulation quality, window area, and orientation. We perform a Manual J load calculation on every installation — not a rough estimate — to ensure proper sizing.

Yes! CenterPoint Energy and other Houston-area utility providers offer rebates for qualifying high-efficiency HVAC systems. We'll help you identify and apply for available rebates at the time of your installation.

A heat pump provides both heating and cooling from a single system and is highly efficient in Houston's mild winters. A traditional split system uses a separate furnace for heating. We can help you choose the best option for your home.

Annual fall tune-ups are recommended for all Houston furnaces and heat pumps. Even though Houston winters are mild, heating systems that sit unused for months can develop issues before they're needed most.

Leave your home immediately. Don't turn any lights or switches on or off. Call CenterPoint Energy at 713-659-2111 and then call 911 from outside. Do NOT call us until you are safely away. After the gas company clears the scene, call us for repairs.

This is often caused by delayed ignition — gas building up before igniting — which can crack your heat exchanger. It can also be caused by expanding/contracting ductwork. Either way, call a professional. A cracked heat exchanger is a serious carbon monoxide risk.

For Houston's climate, a high-efficiency heat pump (variable-speed, HSPF 9+) is typically the most efficient choice. Gas furnaces are also very efficient and preferable for homes that experience prolonged cold snaps.

Standard 1-inch filters should be replaced every 30–60 days in Houston — more frequently if you have pets, allergies, or live near construction. Houston's humidity causes filters to clog faster than in drier climates.

Skipped maintenance leads to reduced efficiency (higher bills), shortened system lifespan, increased breakdown risk during Houston summer peaks, and can void manufacturer warranties.

You can replace filters and keep the area around your outdoor unit clear. Professional maintenance covers refrigerant levels, electrical testing, coil cleaning, safety checks, and diagnostics that require certified technicians and specialized equipment.

Our comprehensive tune-up includes coil cleaning, refrigerant check, electrical testing, lubrication of moving parts, thermostat calibration, condensate drain cleaning, filter replacement, and a full system performance test.

Houston's average relative humidity is 75%+. Indoor humidity above 60% promotes mold growth, dust mite proliferation, and general discomfort. A properly installed whole-home dehumidifier maintains healthy indoor levels year-round.

Given Houston's combination of industrial air pollution, high pollen counts, and humidity-related mold spores, whole-home air purifiers and UV light systems provide significant health benefits — especially for families with allergies or asthma.

Absolutely. Upgraded MERV filtration, UV germicidal lights, and whole-home air purifiers dramatically reduce airborne allergens. We can assess your current system and recommend effective improvements.

Yes! We offer flexible financing through multiple lenders, including $0 down options and low monthly payment plans. Financing is available for both repairs and new system installations across Greater Houston.

Yes. We regularly offer seasonal specials, new customer discounts, and maintenance plan discounts. Visit our Specials section or ask your technician for current offers.

We charge a standard service call fee for diagnostics, which is credited toward the cost of any repair performed. We will always disclose this fee when you schedule.

We warranty our labor and parts on repairs. Specific warranty terms vary by repair type. Ask your technician for details on your specific job.

New systems include manufacturer warranties (typically 5–10 years on parts, 10 years on compressors) plus our installation labor warranty. We register your warranty immediately after installation.

Yes. We service all types of commercial HVAC systems across Greater Houston, including rooftop units, split systems, chillers, VAV systems, and building automation. We offer 24/7 commercial emergency service and customized maintenance contracts.

Yes. Our commercial division handles projects of all sizes — from single-unit restaurant replacements to multi-zone office building systems across the Houston metro. Contact us for a commercial assessment and quote.

Absolutely. We create customized commercial maintenance agreements tailored to your equipment type, facility size, operational hours, and budget. Monthly, quarterly, and bi-annual schedules available.
