Furnace Maintenance in Lakeway, TX

Quick Fixes for Common Furnace Issues

Many homeowners ignore minor irregularities until they become major system failures. Recognizing the early signs of furnace trouble allows for targeted maintenance that prevents expensive emergency repairs later. If you notice specific symptoms, it indicates that internal components are wearing down or malfunctioning.

Short Cycling

If your furnace turns on and off frequently without reaching the set temperature, it often points to a restricted airflow issue or a faulty thermostat. Dirty air filters are the most common culprit, causing the heat exchanger to overheat and trigger the safety limit switch. Professional maintenance ensures the limit switch and thermostat are calibrated correctly to prevent this strain on the motor.

Unusual Noises

Rattling, banging, or squealing sounds are never normal operation. A squeal often indicates a slipped or frayed blower belt, while banging can signal delayed ignition, where gas builds up before the burners light. This mini-explosion puts immense stress on the heat exchanger. Our technicians identify the source of the noise and tighten or replace loose components before they cause catastrophic failure.

Yellow Burner Flames

A healthy gas furnace should have a steady blue flame. A yellow or flickering flame indicates incomplete combustion, which can lead to the production of carbon monoxide. This is a critical safety hazard. We inspect the burner assembly and air intake to ensure the mixture of gas and oxygen is precise for safe combustion.

High Energy Bills

When a system has not been serviced, it has to work harder to push air through the home. Dust buildup on the blower motor and blower wheel creates drag, increasing electrical usage. Simultaneously, soot on the heat exchanger acts as an insulator, preventing heat from transferring effectively to the air in your ducts. Cleaning these components restores energy efficiency.

What Our Furnace Maintenance Service Includes

A proper furnace tune-up is not just a quick visual check; it is a deep cleaning and calibration of the system’s vital components. We follow a rigorous checklist designed to meet manufacturer warranty requirements and ensure the longevity of your investment.

Safety Controls and Ignition System Testing

We test the limit switch, the pilot light or hot surface igniter, and the flame sensor. The flame sensor is particularly important; if it becomes coated in oxidation/carbon, it cannot detect the fire, causing the gas valve to shut prematurely. We clean this sensor to ensure reliable ignition.

Heat Exchanger Inspection

The heat exchanger is the component that separates the combustion gas from the air you breathe. We inspect this metal chamber for cracks or corrosion. Even a hairline crack can allow exhaust gases, including carbon monoxide, to leak into the supply air. This is a non-negotiable safety step in our maintenance process.

Blower Motor and Electrical Assessment

We measure the amperage and voltage of the blower motor to ensure it is drawing the correct amount of power. We also tighten all electrical connections. Loose connections can cause wires to overheat and burn out, leading to sudden system failure. If the motor requires lubrication, we apply it to reduce friction and wear.

Gas Line and Valve Calibration

We inspect the gas piping entering the furnace for leaks and verify that the gas valve is opening and closing correctly. We also check the manifold gas pressure. If the pressure is too high, it can overheat the unit; if it is too low, condensation can form in the heat exchanger, leading to rust.

Thermostat and Airflow Verification

We verify that your thermostat is reading the room temperature accurately and communicating effectively with the furnace control board. We also inspect the ductwork connections at the unit to ensure there is no air leakage, maximizing the warm air delivered to your living spaces.

Our Furnace Service Process: What to Expect

When you schedule maintenance in Lakeway or the surrounding areas, we prioritize a streamlined, unobtrusive process that respects your time and property. We handle everything from the initial diagnostic to the final system test.

Arrival and Site Protection

Our technicians arrive with fully stocked trucks, ready to address most issues on the spot. We wear shoe covers and use drop cloths to protect your flooring around the work area. We begin by listening to your concerns regarding the system's recent performance.

System Diagnostics and Cleaning

We shut off power to the unit to safely access internal components. We proceed with the cleaning of the burners, blower assembly, and sensors. We then move to the inspection phase, using specialized tools to test electrical loads and gas pressure.

Testing and Calibration

Once the physical cleaning and inspection are complete, we restart the system. We cycle the furnace through a full heating call, monitoring the temperature rise (the difference in temperature between the supply and return air) to ensure it falls within the manufacturer’s specified range.

Reporting and Recommendations

After the service is complete, we provide a detailed report of our findings. If we identify a part that is nearing the end of its life, we provide a clear explanation and a quote for the repair. You are never pressured; we simply provide the data you need to make an informed decision.

Deciding Between Furnace Repair and Replacement

There comes a point where maintaining an aging system is no longer the most financial, prudent choice. Understanding when to stop repairing and choose replacement is key to managing your home comfort budget.

The Age of the Unit

Most gas furnaces last between 15 and 20 years. If your unit is approaching or has surpassed the 15-year mark, major repairs are often throwing good money after bad. Newer models are significantly more efficient, meaning the monthly savings can help offset the cost of installation.

The 50% Rule

A general guideline in the industry is the 50% rule. If the cost of the repair approaches 50% of the value of a new system, replacement is usually the better option. For example, replacing a cracked heat exchanger or a failed blower motor on an old unit is labor-intensive and costly.

Frequency of Breakdowns

If you have required repairs more than twice in the last two years, your system is becoming unreliable. Frequent breakdowns indicate that multiple internal components are failing in succession. AC Superheroes can provide a cost-benefit analysis to help you determine if a new, warranty-backed system is a smarter investment.

Uneven Heating and Comfort Issues

If some rooms are freezing while others are hot, or if the house feels dry and dusty despite filter changes, the furnace may no longer be sized correctly or capable of distributing air effectively. Modern systems offer variable-speed blowers that provide more consistent, comfortable heat.

Understanding Texas Heating Needs and Regulations

Heating in Texas presents a unique set of challenges compared to colder northern climates. While we do not experience months of sub-zero temperatures, the "start-stop" nature of our winters puts specific stress on heating equipment.

Seasonality and Disuse

In our region, a furnace may sit idle for eight to nine months out of the year. This long period of inactivity can lead to issues such as rust accumulation on burners, spiders building webs in the pilot assembly, or seized motor bearings. When the first freeze hits in late November or December, the system is forced to go from zero to maximum capacity instantly. This is why pre-season maintenance is critical in this climate.

Permits and Safety Codes

When installing or significantly modifying gas heating systems, local building codes must be followed strictly. This includes proper venting requirements to prevent back-drafting of exhaust gases and adherence to gas line sizing regulations. We handle all necessary compliance aspects, ensuring your system meets local safety standards.

Utility Rebates and Efficiency

Many local utility providers offer rebates for upgrading to high-efficiency heating systems or performing specific maintenance tasks that improve energy conservation. We stay updated on current rebate programs to help you maximize your savings. Moving from an 80% AFUE furnace to a 95% AFUE unit can result in substantial utility savings during the heating season.
