Replaced the old with the new. I got a fantastic price on the new heat pump system. The installation went really smoothly, and it is working great. I like this company.

We’ve been clients of Ellis for 20+ years at our home and office. Yesterday we woke to no heat, of course with the coldest temps of the year just 2 days away, we called Ellis.

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

A furnace usually gives off a few warning signs before it stops working altogether, and it helps to know what to watch for.

  • Furnace won’t turn on
  • Blowing cold or lukewarm air
  • Strange banging or rattling sounds
  • Burning smell when running
  • Frequent cycling on and off
  • Higher than normal heating bills

If you’re noticing any of these, it’s worth having a technician take a look before the next cold front moves through.

What Usually Goes Wrong With Furnaces

In Red Oak, one of the most common furnace issues we see is simple neglect, not because homeowners are careless, but because Texas winters give a furnace so little regular use that small problems can go unnoticed for months. A dirty filter, a worn out igniter, or a faulty thermostat can sit undetected until the first real cold snap forces the system to work harder than it has in months.

Red Oak’s rapid growth also means a lot of furnaces here are original equipment installed during new home construction, and builder grade systems aren’t always matched precisely to a home’s actual heating needs. Add in the settling that happens as new homes sit on the area’s clay soil, and ductwork connections can shift slightly over time, leading to air leaks that make a furnace work harder than it should just to keep the house warm.

Our Furnace Repair Services

We repair every major furnace issue, including ignition problems, faulty blower motors, thermostat malfunctions, and heat exchanger concerns. If your furnace won’t start, blows cold air, or trips the breaker repeatedly, our technicians can identify the root cause and walk you through your repair options.

Because furnace problems in Red Oak often come from systems that see so little use throughout the year, we start every visit with a full inspection rather than assuming the obvious symptom is the whole story. Our trucks are stocked with common parts so most repairs can be finished in a single visit, which matters when a cold front is expected to move through the area.

Inside a Typical Service Visit

In Red Oak, we got a call from Diane, whose furnace wouldn’t turn on at all during an unexpected cold snap in the middle of winter. Our technician found a failed igniter, a common issue on systems that sit unused for most of the year, and had a replacement part on the truck. Within the hour, the furnace was running and heating the house evenly again. Diane mentioned she hadn’t thought about her furnace since the previous winter, so our tech suggested a fall tune up going forward to catch small issues like this before the cold weather arrives.
