Gas Furnace Repair in Mount Vernon, TX

Is your furnace blowing cold air, making noise, or refusing to start? Our licensed HVAC experts repair all makes and models. We explain what we find and what we recommend, and we will not sell you a repair you do not need. If the furnace is worth saving, we fix it. If it is not, we say so.

Common furnace problems we repair:

• Furnace blowing cold air or heating unevenly
• Furnace will not turn on or will not stay lit
• Short cycling, where it turns on and off repeatedly
• Banging, squealing or rattling noises
• Weak airflow from the vents
• Thermostat and control problems
• Heating bills climbing because the furnace runs longer than it should

If you smell gas, leave the house and call your gas provider or 911 first. Then call us.

Furnace Installation and Replacement

Sometimes a repair is not the best use of your money. A furnace that is old, breaks down often, or costs more to run every winter may be cheaper to replace than to keep fixing. We will tell you which one applies to yours, and we will not patch a furnace that needs replacing.

If you do need a new furnace, we are a Carrier Authorized Dealer and install Carrier gas furnaces. Every installation starts with sizing your home's heating load rather than copying the size of the old unit, because a furnace that is too big or too small wears out sooner and heats less evenly. We will walk you through all of your options, including single-stage, two-stage, and variable-stage.

Ask about our financing options when you request an estimate.

Signs it may be time to replace your furnace:

• It is 15 years old or more (gas furnaces often last 15 to 20 years)
• Repairs are more frequent or more expensive each year
• Some rooms stay cold or the furnace runs nearly nonstop
• Your heating bills keep rising
• It has become noisy

What Are the Different Types of Furnaces?

Single-Stage: A single-stage furnace runs at full output whenever it is on, then shuts off when the house reaches the set temperature.

Two-Stage: A two-stage furnace has two settings—full and half speed. This is a more efficient way to heat and provides for better comfort, because it can move the air at a slower pace.

Variable-Stage or Modulating: A variable-stage or modulating furnace adjusts its speed and heat output based on how much heat your home needs and your desired comfort level. It only works as hard as it has to, making this type the most energy-efficient type of furnace.

How Much Money Can a New Furnace Save You?

Our AFUE energy savings calculator can help determine how much you could save on your utility bills. Simply enter your current unit's AFUE value and compare it to a newer, more efficient system. You can even customize it to better match your home's system for a more accurate calculation.

Furnace Maintenance and Tune-Ups

A yearly tune-up is the cheapest way to avoid a no-heat call in January. A technician inspects and cleans the key components, tests the safety controls, and checks how the furnace is performing, so small problems get fixed before the first cold snap. A well-maintained furnace runs more efficiently and tends to last longer.

Book your tune-up in early fall, before heating season starts. Between visits, check your air filter regularly and replace it on your manufacturer's schedule. A dirty filter restricts airflow, makes the furnace work harder and can lead to a breakdown.

Gas Furnace FAQs for Mount Vernon Homeowners

Should I repair or replace my furnace?

If a repair would cost about half the price of a new furnace and the unit is past 15 years old, replacement usually saves money. If the furnace is newer and the problem is a single part, repair usually wins. Our technicians will give you an honest recommendation either way.

Why is my furnace blowing cold air?

Common causes are a thermostat fan set to "On" instead of "Auto," a dirty air filter, an igniter or pilot problem, or a safety switch shutting off the burners. Check the thermostat and filter first. If the air is still cold, call (903) 537-4531 and we will diagnose it.

What is AFUE?

AFUE stands for Annual Fuel Utilization Efficiency. It shows how much of the gas a furnace burns becomes heat for your home. A 95% AFUE furnace turns about 95 cents of every fuel dollar into heat, while an older 70% unit wastes about 30 cents. Higher AFUE means lower fuel use. Use the calculator above to compare your current furnace to a new one.

What size furnace do I need?

The right size depends on your home's square footage, insulation, windows, ductwork, and local climate, not just the size of your old furnace. A bigger furnace is not a stronger one: an oversized unit heats the house quickly, shuts off, and repeats, which wastes fuel and wears out parts. We calculate the BTUs your home needs before recommending a model. Call (903) 537-4531 to set up an appointment.

How often should a furnace be serviced?

Once a year, ideally in early fall before heating season. Annual service catches worn parts early and keeps the furnace running efficiently.

How long does a gas furnace last?

Most gas furnaces last 15 to 20 years with regular maintenance. Age alone does not mean you must replace it, but a furnace in that range that needs frequent repairs is usually a replacement candidate.

Do you repair all furnace brands?

Yes. We repair and service all makes and models of gas furnaces. For new installations, we are a Carrier Authorized Dealer.

Do you offer financing for a new furnace?

Yes. We offer financing options with quick approvals and can walk you through the application and monthly payment options. Read about financing a new HVAC system, or ask when you request an estimate.
