Heating Repair in Houston, TX

Several warning signs indicate your heating system needs professional attention. Unusual noises like banging, whistling, or grinding often signal mechanical problems with components like the blower motor or belts, which require immediate repair to prevent cascading failures. Inconsistent heating throughout your home, where some rooms feel too cold while others are too warm, points to significant distribution or airflow issues within your system. A sudden and unexplained spike in your energy bills suggests your heater is working inefficiently and struggling to maintain temperature. For gas furnaces, a yellow pilot light instead of a crisp blue one can indicate dangerous carbon monoxide production, requiring immediate professional intervention. Frequent cycling, where the system turns on and off repeatedly, or a system that fails to ignite properly are also red flags. Strange odors, particularly burning smells or the scent of gas, warrant immediate attention as they could indicate serious safety hazards. At AC On Time, we recommend scheduling a professional inspection if you’re experiencing any of these symptoms to ensure your home remains safe and comfortable.

Heating repair costs vary significantly depending on the specific issue and the type of system you have. Minor repairs, such as replacing a faulty thermostat, a simple sensor, or a standard furnace ignitor, are generally on the lower end of the cost spectrum. However, more complex issues, like repairing or replacing blower motors, control boards, or draft inducer motors, can be substantially more expensive due to the cost of the parts and the labor involved. The age and type of your heating system also play substantial roles in determining repair costs, as newer, high-efficiency models sometimes require specialized parts.

Deciding between repairing or replacing your heating system depends on several key factors. As a general rule, if your system is less than 10-12 years old and the repair costs are under 50% of a new system’s value, repairs typically make more financial sense for the short term. However, for systems older than 15 years that experience frequent breakdowns, replacement often proves more economical in the long run, especially considering the significant energy efficiency improvements of modern units. At AC On Time, we perform a comprehensive cost-benefit analysis for our customers, factoring in your system’s age, repair history, and current efficiency rating. Energy savings alone can justify replacement, as newer systems can reduce heating bills by 20-40%. We never recommend unnecessary replacements; if your system can be reliably repaired at a reasonable cost, we’ll always present that as a primary option. However, critical safety concerns like a cracked heat exchanger, which can leak carbon monoxide, will almost always warrant immediate replacement regardless of the system’s age.

We recommend having your heating system professionally serviced at least once per year, ideally in the early fall before the heating season begins. This annual maintenance is crucial for ensuring optimal performance, preventing unexpected breakdowns during cold weather, and maintaining your manufacturer's warranty, which often requires documented regular service. For homes with heat pumps that handle both heating and cooling, we suggest bi-annual servicing—once for each season. During our comprehensive maintenance visits, our technicians clean vital components, lubricate moving parts, check all electrical connections, meticulously test safety controls, and inspect the heat exchanger for any signs of cracks or stress. We also replace customer-provided filters, which should ideally be changed every 1-3 months depending on your home's air quality needs. Regular maintenance significantly extends your heating system’s lifespan, with properly maintained units typically lasting years longer than neglected systems, making it a wise and affordable investment in your home's comfort and safety.

A sudden furnace failure can stem from various issues, ranging from simple fixes to complex problems requiring professional intervention. One of the most common causes is a tripped circuit breaker or a blown fuse in your home's electrical panel. Another frequent culprit is a malfunctioning thermostat, which could have dead batteries or be set incorrectly. A severely dirty or clogged air filter is a major cause, as it restricts airflow, causing the system to overheat and trigger its safety shutoff mechanism. Beyond these, the problem could lie with the fuel supply, such as a closed gas valve or an issue with the utility provider. Modern furnaces have numerous safety features, and a failure in the ignition system, such as a faulty ignitor or flame sensor, will prevent the burners from lighting. At AC On Time, our technicians are trained to quickly diagnose these issues using systematic troubleshooting techniques. While checking the thermostat and breaker are safe DIY steps, most other causes require a professional diagnosis to ensure safety.

Unexpectedly high heating bills often result from a combination of system inefficiencies and household factors. An aging heating system naturally loses efficiency over time, causing it to consume more fuel or electricity to produce the same amount of heat. Inadequate home insulation and air leaks around windows, doors, and in the attic allow the warm air your system produces to escape, forcing your heater to work harder and run for longer cycles. A dirty or clogged air filter is a primary offender, as it restricts airflow and makes the system struggle to circulate air. Furthermore, leaky ductwork can be a major source of energy waste, losing up to 30% of heated air into unconditioned spaces like attics or crawlspaces. Even an improperly calibrated thermostat can cause the system to run inefficiently. During our maintenance visits, we can tune your system for optimal efficiency and provide recommendations for addressing other household factors that may be contributing to excessive energy consumption and high utility costs.

Improving your heating system’s efficiency involves both professional maintenance and simple homeowner practices. The foundation of efficiency is an annual professional tune-up, where our technicians clean vital components and ensure all parts are functioning correctly, which can improve efficiency by up to 15%. As a homeowner, the single most effective task is replacing your air filters every 1-3 months during the heating season; this prevents airflow restrictions that force your system to work harder. Upgrading to a programmable or smart thermostat can save significantly on heating costs by automatically lowering temperatures when you’re away or asleep. Sealing leaky ductwork is also critically important, as the average home loses a large percentage of heated air through these leaks. Finally, ensuring your home is well-insulated, particularly in the attic and around windows, keeps heat inside longer. Combining these professional services and homeowner habits will ensure your system runs at its peak performance, saving you money on utility bills.

A furnace blowing cold air is a common and frustrating problem with several potential causes. The first thing to check is your thermostat settings; ensure it is set to "HEAT" and not "FAN," which only circulates unheated air. Another frequent cause is an overheated furnace. If your air filter is severely clogged, it can restrict airflow, causing the furnace to overheat and shut off its burners as a safety precaution, while the fan continues to run. The issue could also be with the ignition system. If the pilot light is out on an older furnace or the electronic ignitor has failed on a newer one, the burners cannot light to generate heat. A more serious issue could be a problem with your gas supply, such as a closed valve, or a faulty flame sensor that incorrectly tells your system the burners aren't lit. Our technicians can systematically diagnose the root cause, from simple fixes to more complex component repairs, to safely restore warm air to your home.

A burning smell coming from your heater can be alarming, but its seriousness depends on the type of odor and when it occurs. If you notice a dusty, slightly burnt smell the first few times you turn on your heater for the season, it is typically normal. This is usually just the smell of accumulated dust burning off the heat exchanger and internal components after a long period of inactivity; this smell should dissipate within an hour or two. However, if you detect a sharp, acrid, or electrical burning smell that smells like melting plastic or rubber, it could indicate a serious problem like an overheating blower motor, frayed wiring, or a foreign object trapped in the unit. This poses a significant fire risk and requires immediate attention. If you experience this type of smell, you should turn off your heating system at the thermostat and the circuit breaker immediately and call for emergency professional service. Never ignore a persistent or electrical burning odor.
