Furnace Replacement in Katy, TX

Furnace replacement is a full day's work, and in Katy that often means an attic install with tight clearances, a flue that needs reworking and a condensate path that has to drain properly. We pull the old unit, correct the plenum connections, verify gas piping and set combustion before we leave. You see the old heat exchanger and why it is being retired. Ring us with your model number, or use the quote form and we will schedule a look.

Why Katy homes end up needing this

We keep paying for heating repair every winter Repeat failures on an aging system, replacement usually cheaper than the next three visits
Some rooms never get warm, others cook Undersized returns and duct problems that a new furnace alone will not fix
There is rust and water staining under the unit Long-term condensate or drain pan leak eating the cabinet and burners

What a Furnace Replacement Job Involves

We start by shutting down and safely disconnecting the old furnace, then removing it along with any failed flue or venting that will not carry over. The new unit gets set, leveled and connected to the gas line, electrical, condensate and duct plenum. We check the return side, because a lot of homes in the region were built with returns too small for the airflow the equipment wants. Then we fire it, measure temperature rise, and confirm the thermostat and safeties respond the way they should before we leave.

What We Check and Install

Before we quote anything we measure the house, not just swap the same BTU rating back in. We look at duct condition, static pressure, the flue path, the gas supply and the electrical circuit feeding the air handler. In attic installs we check the platform, the drain pan and the secondary drain line. On the install itself we set a new filter cabinet where the old one was undersized, seal the plenum connections, and label the disconnect so any future heater repair is straightforward.

How We Decide Replacement Is the Right Call

A cracked or rusted heat exchanger means the furnace comes out, full stop, because that is a combustion safety issue. Past that, we weigh age, the cost of the parts it needs, whether those parts are still made, and how the unit has been performing through the last few winters. If a furnace repair will get you several more seasons for a fraction of new equipment, we say so. If you smell gas, leave the house, call 911 or your gas utility, then call us.

Furnace Replacement in Katy — quick answers

How long does a furnace replacement take?

Most straightforward swaps take a single day. Attic installs, tight closets, or jobs that need venting and duct work corrected can run into a second day, and we will tell you that up front.

Should I replace the AC at the same time?

If the outdoor unit is a similar age and shares the indoor coil and blower, replacing together often makes sense. We will look at both and give you an honest read rather than pushing a bigger job.

How soon can you get to my house in Katy?

Call us with your address and we will give you the next available window, usually same day or next day depending on how the schedule is running. Heat calls in July fill up early, so morning calls get the best slots. Tell us if the system is off entirely, if there is water in the attic, or if anyone in the house is elderly or ill, because that changes how we order the day.

Step 2
We diagnose on site
A technician checks the thermostat, airflow, the indoor coil and blower, then the outdoor unit and electrical side. You get a plain explanation of what failed and why it failed.
Step 3
You approve the repair
We walk you through the fix and any parts involved before we start. Once you say go, we make the repair and confirm the system is holding temperature before we leave your driveway.

Built for hard summersWe work on attic air handlers in July heat, undersized returns in older subdivisions, and condensers with hail-flattened fins. Those are everyday jobs across the region, so we know where these systems tend to give out first.
Air conditioner repair and heating repairOne crew for both seasons. Air conditioning repair when the house won't cool, heater repair and furnace repair when the burners won't stay lit. Same technicians, same records, so nobody starts from scratch in November.
We explain the failureYou hear which component failed and what it was doing to the rest of the system. If a repair is a short-term patch on an aging unit, we say so and let you decide the timing.
Respect for the houseDrop cloths, shoe covers, and the attic hatch closed the way we found it. We keep the work area clean and we tell you honestly when a problem is airflow or ductwork rather than the equipment itself.
