HVAC Company in Keller, TX for Homes That Have Stood the Test of Time

Keller’s population more than doubled between the 1980s and 2000s as families left Fort Worth and Dallas looking for more space and better schools, and Keller ISD’s reputation grew right along with the city. That boom mostly ended two decades ago. With little open land left to develop, Keller today is a largely built-out community of established neighborhoods, mature trees, and homes that are old enough to be on their second or even third HVAC system. That’s a very different starting point than a town where most homes were built in the last five years, and it changes what HVAC service typically means for the people who call us.

A lot of the AC and furnace units installed during Keller’s growth years are now twenty to thirty years old, well past the typical service life of residential HVAC equipment. Some of those systems still run on R-22 refrigerant, which the EPA phased out of production entirely in 2020, making repairs on those older units more expensive and less practical every year. If your system falls into this category, replacement is often the more cost-effective option long term, even if the unit is technically still running.

Signs Your System May Be Nearing Replacement

• Your system is 15 years or older
• You’ve needed more than one or two repairs in the past year
• Your technician has mentioned the unit uses R-22 refrigerant
• Your energy bills have crept up despite normal usage
• The system struggles to keep up on the hottest or coldest days

Not every issue means it’s time for a new system, and we won’t tell you it is unless the numbers actually support it. Our technicians diagnose the real problem first, whether that’s a failing capacitor, a refrigerant leak, or a compressor on its way out, and give you a straightforward recommendation for repair or replacement based on your system’s age, condition, and repair history.

The same age-related issues that show up in Keller’s air conditioners tend to show up in furnaces too. Our heating services include:

• Furnace repair for gas, electric, and heat pump systems
• Full furnace and heat pump replacement
• Thermostat repair, replacement, and smart thermostat installation
• Pre-winter safety inspections, especially important for older gas furnaces

Old Town Keller has been carefully preserved even as the rest of the city modernized, and many of the buildings and homes in that area predate most of Keller’s suburban growth entirely. Heating and cooling a historic structure often means working around original construction, older wiring, and ductwork that was never designed for a modern high-efficiency system. We take the extra time to assess these properties individually rather than treating them like a standard suburban install.

Southern Comfort Mechanical has been family owned and operated since 2007, and we’ve built our reputation on honest assessments rather than upselling. In a city like Keller, where a large share of our work involves older systems, that honesty matters even more. We back every job with a satisfaction guarantee, whether it’s a same-week repair or a full system replacement.

In addition to Keller, our Flower Mound-based team regularly serves the nearby communities of Southlake, Trophy Club, and Flower Mound. See our full Service Area for complete HVAC and plumbing coverage details in each community.
