Ellis air installed an infinity heat pump system at our home 15 years ago. Best thing we have ever done. It has preformed beautifully over the years and is still going strong thanks to Ellis Air.

Signs Your Furnace Needs Repair

Furnace trouble in Glenn Heights can show up a little differently depending on the type and age of your system, but a few signs are worth watching for across the board.

  • Furnace won’t ignite
  • Weak or inconsistent heat
  • Musty smell when running
  • Strange noises at startup
  • Rising heating costs
  • Vent or exhaust blockage

If you notice any of these, especially a blocked vent, it’s worth having a technician take a look right away.

What Usually Goes Wrong With Furnaces

In Glenn Heights, one issue we run into more than most other parts of the area is fallen leaves and yard debris finding their way into furnace vents and exhaust flues, thanks to the mature tree cover found throughout many of the city’s older neighborhoods. When a vent or flue gets partially blocked, a furnace can struggle to exhaust properly, which is both a performance issue and a safety concern that needs prompt attention.

The other common factor is the wide age range of furnaces across the city. Because Glenn Heights developed in stages over several decades and sits across two counties, homes here run everything from older standard efficiency furnaces to newer high efficiency units with different venting requirements. That variety means our technicians have to correctly identify what kind of system they’re working on before diagnosing the problem, since a fix that works on one type of furnace won’t necessarily apply to another.

Our Furnace Repair Services

We repair furnaces of every type and age, including standard efficiency models with metal flues and newer high efficiency systems with plastic venting. Our technicians check ignition components, blower motors, thermostats, and heat exchangers, and we pay close attention to venting and exhaust, especially in neighborhoods where fallen leaves and debris are more likely to cause blockages.

Every repair visit starts with identifying your specific furnace type and checking the whole system, not just the obvious symptom. Our trucks carry parts for a wide range of furnace models, so most repairs are completed in a single visit regardless of your system’s age or type.

Inside a Typical Service Visit

In the Meadow Creek Estates neighborhood of Glenn Heights, we got a call from Nathan, whose furnace kept shutting off shortly after starting up. Our technician found the exhaust vent was partially blocked by leaves that had collected over the fall season, which was tripping a safety switch designed to shut the furnace down when venting isn’t clear. After clearing the blockage and confirming the furnace was venting properly, the system ran through a full cycle without any issues. Nathan hadn’t realized the vent needed regular clearing, so our tech suggested checking it each fall before the heating season begins.
