Furnace Maintenance

Furnace Maintenance is the scheduled service that keeps your system from turning a $40 filter change into a $600 repair. In Houston’s climate, your furnace sits dormant for months at a stretch, then cycles hard during cold snaps – that pattern lets dust settle, belts dry, and electrical connections loosen. A furnace maintenance visit from Dalton Heating & Air Houston costs $80 to $200 depending on your unit and includes a written report of what we found. We clean the burners, test the ignition, check gas pressure, and measure the heat rise across the exchanger. If a part looks weak, we show you the price in writing before ordering it.

Fall Tune-Up Before the First Cold Front

Houston’s first real cold front usually hits in late October or early November. Booking a maintenance visit in September or October means your furnace is ready when the overnight low drops into the 30s. We also check carbon monoxide readings on gas units as standard practice, not as an add-on.

What Maintenance Catches Early

A cracked heat exchanger almost never announces itself until it’s a safety problem. During maintenance we inspect for hairline cracks that let combustion gases into your ductwork. Catching one early costs a fraction of what a midwinter emergency repair does.

Heat Pump Repair

Heat Pump Repair covers the systems many Houston homes rely on for both heating and cooling, which means a heat pump failure hits you twice a year instead of once. A heat pump works by reversing refrigerant flow to move heat rather than burn fuel, so the failure points are different from a gas furnace: reversing valves, defrost boards, and outdoor coils take the most abuse in Texas humidity. Dalton Heating & Air Houston repairs heat pumps with the same written pricing and full-year written guarantee as any other job. Repairs typically run $150 to $700 depending on the component that failed. Marco Benitez, our Houston lead, has been diagnosing heat pump reversing valve and defrost issues since the company’s earliest days in the trade.

Defrost Cycle Problems in Humid Air

Houston’s humidity loads the outdoor coil with moisture, and when the defrost board fails, the coil ices over and the unit runs constantly without producing heat. We test the defrost sensor, the board, and the reversing valve together because one failing part often drags the other two with it.

Refrigerant Leaks on the Outdoor Coil

A heat pump losing refrigerant – the fluid that carries heat between the indoor and outdoor units – loses heating capacity before it loses cooling capacity. That’s why a Houston heat pump that cools fine in July might not heat in January. We pressure-test with nitrogen, locate the leak, and quote the repair before we recover or add any refrigerant.

Heating Repair

Heating Repair is the broad term for any service that restores heat to a home, whether the source is a gas furnace, a heat pump, or electric strip elements. The most common call we get in Houston is a furnace that starts, runs for a few minutes, then shuts off before the house warms up. That’s usually a limit switch, a dirty flame sensor, or a failing blower motor. Dalton Heating & Air Houston handles all of it at $150 to $700 for most repairs, always with the price in writing before work starts. We service all nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard.

Short Cycling and Overheating

When a furnace starts and stops every few minutes, it’s working against a restriction – a clogged filter, closed vents, or an overheating exchanger. We measure static pressure and temperature rise to find the restriction instead of just resetting the limit switch and leaving. The Garrison Code requires us to fix the cause, not reset the symptom.

Blower Motor and Airflow Repairs

A furnace that burns fine but moves no air is a blower problem, not a heating problem. We test capacitors, motor windings, and the control board before quoting a replacement. Most blower repairs fall in the $250 to $600 range, and you’ll see the exact number in writing before we install anything.

Boiler Repair

Boiler Repair in Houston is less common than our Furnace Repair in Highlands, but plenty of older homes in neighborhoods like The Heights and Garden Oaks still run hydronic heat – hot water circulated through pipes instead of air pushed through ducts. The failure points on a boiler are different: circulator pumps, expansion tanks, pressure relief valves, and zone controls. Dalton Heating & Air Houston repairs residential boilers at $150 to $700 for most jobs. Pressure and temperature issues are the usual culprits, and we don’t guess – we measure with a manometer and verify with a combustion analyzer. The written guarantee applies here exactly as it does on a gas furnace.

Circulator Pump and Zone Valve Failures

When one room heats and another stays cold on a boiler system, the zone valve or circulator pump for that loop has usually failed. We test the valve motor, the end switch, and the pump impeller before replacing anything. Most homeowners see the difference the same day we fix it.

Pressure and Expansion Tank Problems

A boiler that dumps water from the relief valve or bounces pressure when it heats is telling you the expansion tank has failed. Left alone, it shortens the life of the boiler itself. We check tank air pressure first because it’s a $120 fix that prevents a $700 repair.

Gas Furnace Repair

Gas Furnace Repair is the work we do most often in Houston between November and February, when natural gas furnaces carry the heating load for millions of single-family homes. The specific issues are ignition failure, flame sensor drift, gas valve malfunction, and heat exchanger cracking. Dalton Heating & Air Houston fixes all of them with written pricing first and a full-year written guarantee after. Most gas furnace repairs run $150 to $700 depending on the part. Here’s a safety point you won’t hear from every company: if you smell gas or hear a puffing sound from the burner area, turn the furnace off at the switch and call us at (903) 494-7686. Gas and combustion work is not a DIY project – a trained technician with a combustion analyzer should verify gas pressure and carbon monoxide levels after any repair.

Ignition Sequence and Flame Sensor Issues

A furnace that clicks, tries to light, then shuts down usually has a dirty flame sensor. The sensor confirms the burners lit, and when it’s coated with residue from Houston’s humidity and dust, it sends a false “no flame” signal. We clean or replace it, then verify the reading in microamps before we leave.

Gas Valve Regulator Testing

When a furnace lights but the flame is lazy and yellow, the gas valve is often delivering wrong pressure. We test with a manometer on both the supply and manifold sides. A bad gas valve is a $300 to $550 repair, and you’ll see the exact quote before we order the part.

Furnace Tune Up

A Furnace Tune Up is a 21-point service that prepares your heating system for the season and costs $80 to $200 in Houston. It’s different from a maintenance visit in scope – a tune up tests and adjusts, where maintenance includes replacement of wear items. During a tune up, Dalton Heating & Air Houston techs inspect the heat exchanger for cracks, clean the burner assembly, test the ignition, measure gas pressure, check the venting for blockages, and run the full cycle to verify proper operation. We leave you a written report of what we found, and if something needs repair, the tune up fee is credited toward the repair. That’s part of The Garrison Standard: you never pay twice for a diagnosis.

Combustion Analysis and CO Testing

Every tune up on a gas furnace includes a combustion analyzer reading and a carbon monoxide check near the unit and at the supply registers. Houston homes with newer construction seal tightly, which means even low-level CO can linger. We treat this as standard, not an upcharge.

Written Findings You Can Read

After the tune up, you get a written summary: what passed, what’s marginal, and what we recommend with prices. Our techs are not paid on what they sell – the report is honest because their pay doesn’t depend on the recommendations. That’s a Garrison family rule since 2003.

Emergency Furnace Repair

Emergency Furnace Repair is what you need when the furnace dies during a Houston cold snap and the house drops below 50 degrees with kids or older adults inside. Dalton Heating & Air Houston answers every emergency call with a live person, 24 hours a day, 7 days a week – no answering service, no callback window. Emergency repairs run $150 to $700 for most jobs, and we do not charge overtime rates just because it’s 2 a.m. The price you see in writing is the price you pay, emergency or not. If you’re in Houston, Pearland, or Baytown - or need Furnace Repair - Galena Park - our emergency response time is typically under 90 minutes. Call (903) 494-7686 and a technician will be dispatched.

No-Overtime Emergency Pricing

Many Houston companies inflate nighttime and weekend calls by 50 percent or more. The Garrison Code forbids that. An emergency repair at 10 p.m. costs the same as the same repair at 10 a.m., and it’s always in writing before we begin.

When Cold Is a Health Risk

A house at 45 degrees is dangerous for infants, the elderly, and anyone with respiratory or circulatory issues. If you’re in that situation, don’t wait until morning. We prioritize occupied homes with vulnerable residents, and we’ll tell you honestly over the phone whether a repair can hold overnight or needs immediate attention.

Brands We Service

Dalton Heating & Air Houston is factory-trained on nine major residential HVAC brands, and we carry OEM parts for the ones Houston homeowners own most. Our techs see hundreds of Carrier gas furnaces every winter across Spring, Furnace Repair in Humble, and Stafford – the common issue there is the inducer motor, and we stock those on our trucks. Trane units, especially the XR and XL series, cross our service boards regularly in Pearland and Friendswood, where the variable-speed blower modules need the right diagnostic sequence to avoid misdiagnosis. Lennox systems are common in Rosenberg and Fresno, and we know the difference between an SLP98 and an ML195 control board without guessing. Goodman furnaces make up a large share of the newer homes in Sienna Plantation and Seabrook, and we keep their igniters and pressure switches on the truck. Whether you have a Carrier, Trane, Lennox, Goodman, or any other make, we can help – we service Rheem, York, Daikin, Bryant, and American Standard with the same written pricing and one-year written guarantee.

The brand on the cabinet matters less to us than the condition of the unit and the quality of the last repair. What matters to you is that the tech who arrives knows the sequence of operations for your specific model. Our factory training covers that, and our trucks carry diagnostic gear calibrated for each brand’s tolerances. If you’re not sure what unit you have, call us and read the model number off the data plate – we can usually tell you over the phone what you’re dealing with.

Signs You Need a Pro Right Now

• Burning smell from the vents. A dusty smell on first startup is normal and fades in a few minutes. A persistent acrid or electrical smell is not. That’s a motor winding or wiring insulation overheating, and it needs a pro before it becomes a fire hazard.
• Furnace runs but no warm air. If the blower runs and the burners light but the air feels cool, you could have a failed limit switch or a heat exchanger problem. This one builds carbon monoxide risk silently, so don’t run it overnight hoping it sorts itself out.
• Loud banging or rattling inside the unit. A rattling noise is usually a blower wheel coming apart or a loose panel. A loud bang when the furnace lights is delayed ignition – too much gas builds up before the igniter fires. Both are fixable, but they get worse and more expensive if you wait.
• Water pooling around the furnace. High-efficiency condensing furnaces produce water, and when the condensate line clogs, water backs up and trips the pressure switch. A dripping furnace can damage your floor and shut the heat off at the worst time.
• Carbon monoxide detector sounding. If your CO alarm goes off and the furnace is running, evacuate the house first, then call us from outside. We’ll inspect the heat exchanger and venting with a combustion analyzer before we let that unit run again. This is exactly the situation where you don’t want a handyman – you want someone who tests and verifies.

Our Process, Step by Step

1. 1
   You call, a human answers. No phone tree, no “leave a message and we’ll call you back.” You talk to a real person at (903) 494-7686, describe what’s happening, and we schedule a window that fits your day. We confirm the tech’s name before they arrive.
2. 2
   The technician arrives inside the window. Our techs are background-checked, uniformed, and drive marked Dalton Heating & Air vehicles. You’ll know who is at your door before they knock. The Garrison Code requires we arrive inside the stated window, and we do.
3. 3
   Diagnosis with written pricing before work starts. The tech runs the diagnostic – checking the sequence of operations, measuring gas pressure, testing electrical components, and reading for carbon monoxide where applicable. Then you get a written quote with a fixed price before any tool touches a part. The price you see is the price you pay.
4. 4
   Repair done by the book, site left clean. We install OEM or equivalent parts, verify the full cycle runs correctly, and measure the temperature rise or CO output before we pack up. We put down floor protection and clean the work area, every time, no exception.
5. 5
   Written guarantee and follow-up. Every repair carries a one-year written guarantee. If the same part fails within 365 days, we return and fix it at no charge. You get the paperwork with the repair report, and we keep records so any follow-up is fast.
