Keeping Your Home Healthy & Comfortable
Residents of Southlake, TX are fortunate to enjoy mild winter months, but mild winters aren’t necessarily warm winters. Families frequently must run their furnaces, heaters or heat pumps for nearly half the year, especially at night. During the coldest months of the year – December, January and February – having an efficient and properly working furnace is a necessity.
At Tom’s Mechanical, we understand how highly you value your household’s comfort. Your home should be a place of warmth, both literally and figuratively. Our heater repair technicians can ensure your home stays warm by providing fast, effective and honest heater repair. If your furnace stops functioning or isn’t performing at optimal levels, call our technicians right away.
No one enjoys living in a cold house or spending more than they should to keep it warm. Our team is in the comfort business. From a professional standpoint, there’s nothing more important to us than your satisfaction with our heating repair performance. We’ll go above and beyond to ensure your heating issues are sorted quickly and you can get back to enjoying a comfortable home fast.
Having to call out multiple HVAC companies to fix the same problems is extremely inconvenient. We pledge to get your heating issues fixed right the first time or we’ll do whatever it takes to rectify the issue at no cost to you. We’re proud to be the HVAC company many Southlake homeowners call when a competing HVAC company couldn’t do the job or failed to fix it properly.
Heater malfunctions fall into one of two categories: those that result in a complete loss of heating and those that cause inefficient or poor heating performance. It’s easy to spot the first type since you’ll know quickly when your furnace stops putting out heat on a December or January night. The other category can be a bit harder to spot. Some signs it’s probably time to call a heater repair company include:
Homeowners are familiar with the sounds their HVAC systems make. These noises quickly fade into the background of everyday life. However, people usually notice when the sounds their furnace makes are abnormal. You might start to notice strange whirring sounds, buzzing that wasn’t there before or abnormal humming. All are potential warning signs that something might be wrong, especially when coupled with changes in heating performance.
If your thermostat says it’s 70-degrees Fahrenheit but it feels a lot more like 65, it’s probably time to give a heater repair technician a call. We excel at diagnosing and fixing thermostat problems and installing new smart thermostats that can enhance your home’s efficiency and save you money.
If you notice your natural gas bill has increased quite a bit month-over-month despite you using your furnace the same amount, you should strongly consider contacting a furnace maintenance and repair company. There’s a good chance something is wrong with your heater.
During the colder months, your furnace should reach a normal equilibrium of performance. If temperatures haven’t dramatically changed but your system seems to be running far more often or it keeps turning on and off, it may be due to some type of problem. Common issues that cause strange cycling include electrical issues, wiring problems and thermostat malfunctions.
Pilot lights should be blue, not orange or yellow. If you look at your gas furnace and you notice the pilot light is orange or yellow, it means the flame is weaker than it should be and there is either a problem with the gas purity or the supply from the gas line. Any problems with your home’s natural gas can potentially be dangerous and should be addressed as soon as possible.
The root cause of furnace malfunctions can range from abnormal to inevitable. No furnace, even if it’s properly maintained, will last forever. Even those that do provide decades of heating performance may benefit from replacement simply due to inefficiency or frequent breakdowns. Some common causes for furnace failure include:
The team at Tom’s Mechanical has extensive experience diagnosing all types of furnace problems. We know how to quickly determine what’s wrong and provide the best possible repair solution to get your heater working again fast.

While some HVAC companies might immediately jump to suggesting furnace replacement, we’re committed to looking for the most affordable and logical solution first. There are scenarios where you may be best served by upgrading or installing a new furnace, but we’ll always look for ways to fix your existing system first.
