Why Greater Houston Homeowners Trust Us for Furnace Service
Armstrong Equipment Expertise
We install and service Armstrong furnaces, one of the industry’s most reliable brands. Our technicians understand Armstrong’s ignition systems, heat exchanger design, and warranty support. We maintain relationships with Armstrong because their equipment is engineered for durability, and we respect that commitment to quality.
Gas Furnace Specialization
Gas furnace repair and installation require certification and expertise. Our technicians are trained in natural gas safety protocols, proper vent pipe installation, carbon monoxide testing, and efficient burner operation. We handle everything from pilot light issues to cracked heat exchanger diagnosis and full system replacement with zero risk to your family’s safety.
Seasonal Maintenance Prevents Winter Emergencies
Furnace breakdowns happen on the coldest days of the year, when every contractor is slammed. Our pre-winter tune-ups catch wear patterns before failures happen—cleaning burners, testing ignition, verifying airflow, and documenting system performance. This prevents emergency service calls and the stress of being without heating when you need it most.
Emergency Repair Available When You Need It
If your furnace stops heating on a freezing night, we’re ready to respond. We diagnose the problem quickly—whether it’s a failed igniter, a clogged filter reducing airflow, a thermostat malfunction, or a heat exchanger issue—and repair it to restore heat fast.
Transparent Repair Versus Replacement Analysis
Furnace failures can be expensive, and homeowners worry about unnecessary replacement. We run diagnostics first, explain what we find, and present repair options with upfront pricing. If the system is nearing end-of-life, we show you the economics of replacement so you decide based on facts.

What Houston-Area Homeowners Say
Furnace Services We Offer
From emergency repairs on cold nights to planned pre-winter maintenance, LMH Services is ready to help. Contact us to schedule service, request an inspection, or discuss furnace replacement options.
Choosing a new furnace involves understanding your home’s heating load, fuel type (natural gas), duct sizing, and efficiency ratings. We evaluate your existing ductwork, assess heat loss through walls and windows, and recommend equipment sized correctly for your home’s needs.
A properly sized furnace runs efficiently without short-cycling (turning on and off too frequently), which wastes energy and causes temperature swings. We install to manufacturer specifications, verify airflow balance through ducts, test the ignition system, run a complete startup cycle, and confirm carbon monoxide and gas leak safety before you move in. You’ll receive documentation, warranty information, and operating guidance. Learn more about furnace installation.
When your furnace stops heating, diagnosis requires understanding gas ignition, heat exchanger operation, and air circulation. Our technicians test the thermostat, check for electrical power to the igniter, verify the pilot light or electronic ignition, measure gas pressure, and inspect the heat exchanger.
Common furnace failures include failed igniters (most common), clogged filters reducing airflow, thermostat malfunction, limit switches preventing operation, and heat exchanger cracks. We pinpoint the issue, explain what’s wrong, and provide repair pricing. Most repairs are straightforward and affordable; if compressor failure or heat exchanger damage is involved, we discuss replacement options. Discover our furnace repair process.
Regular maintenance keeps your furnace running reliably through cold season and extends its service life. Our pre-winter tune-ups include burner cleaning, ignition system testing, heat exchanger inspection, airflow verification, thermostat calibration, and safety checks.
We test your furnace under load to confirm it’s heating to spec, measuring outlet temperature and verifying the system cycles properly. We also run a carbon monoxide test to ensure your home’s safety—critical because a cracked heat exchanger can leak carbon monoxide into living spaces. Annual service before winter prevents cold-weather emergencies and documents system performance for future reference. See what’s included in furnace maintenance.

Furnace Questions Greater Houston Homeowners Ask
Once yearly, in the fall before heating season begins—ideally September or October. Annual maintenance cleans the burner, tests the ignition and safety systems, verifies airflow, and checks for carbon monoxide leaks. Fall service prevents breakdowns on cold winter nights. If you use your furnace heavily or have a history of problems, twice-yearly service (fall and spring) provides extra reliability.
AFUE (Annual Fuel Utilization Efficiency) measures the percentage of fuel energy converted into usable heat. An 80% AFUE furnace converts 80 cents of every dollar spent on gas into heat; the other 20 cents is lost. Modern high-efficiency furnaces are 95%+ AFUE. Over 20 years, upgrading to a high-efficiency furnace saves thousands in gas bills. The payback period depends on current furnace age and your local gas prices.
Carbon monoxide (CO) from a cracked heat exchanger is extremely dangerous—it’s a silent killer. CO is colorless, odorless, and can cause poisoning at high concentrations. Any crack or leak must be repaired immediately by replacing the heat exchanger. We test for CO leaks during every maintenance visit to catch problems early. Install a CO detector in your home as an extra safety measure.
Some noise is normal—expansion and contraction of metal ducts as warm air flows through them creates clicking and popping sounds. However, loud banging, rumbling, or squealing can signal problems: a dirty burner (causing ignition delay), a failing blower bearing, or loose ductwork. We diagnose unusual furnace noises during maintenance to ensure safety and efficiency.
Yes. During spring and fall, Houston weather swings—cool mornings and warm afternoons. You can run your furnace in the morning and AC in the afternoon. Modern thermostats (especially smart thermostats) handle this automatically, switching between systems based on your setpoint. Manually switching is fine too; just be sure both systems are maintained and ready.
First, check your thermostat—confirm it’s set to heat mode and the temperature setpoint is higher than the current room temperature. Check your air filter; a clogged filter can prevent airflow and trigger a safety shutoff. If these steps don’t restore heat, call us immediately for emergency repair. We respond to heating emergencies on cold nights because a working furnace is essential for safety.
Quality gas furnaces last 15–20 years with regular maintenance. Armstrong furnaces we install are engineered for that range. After 15 years, repair costs often climb as components wear. By year 18–20, most furnaces need replacement rather than continued repair. Proper maintenance (annual tune-ups, timely repairs) extends this lifespan significantly.
If your current furnace is 15+ years old or showing multiple repair needs, a modern high-efficiency furnace (95%+ AFUE) pays for itself through reduced gas bills over time. Exact payback depends on your current gas usage, local gas prices, and furnace age. We calculate this for you during a consultation so you know the financial impact before deciding.
Our maintenance visits include burner cleaning, ignition system testing, heat exchanger inspection, blower motor and wheel inspection, airflow verification, thermostat calibration, safety limit switch testing, carbon monoxide testing, and a complete system startup under load. We document everything and discuss any issues we find before recommending repairs.
Gas furnace installation requires permits, gas fitting certification, and safety testing for carbon monoxide and gas leaks. DIY installation voids manufacturer warranty and creates safety risks. We handle all installation work to code, with full documentation and warranty coverage. Never attempt gas furnace installation without professional help.
