Don't wait until your heating system fails completely — these warning signs indicate it's time for a replacement.
Most furnaces last 15-20 years. If yours is approaching or exceeding this age, a new energy-efficient installation will save money on repairs and utility bills.
Increasing heating costs despite similar usage patterns indicate declining efficiency. A new heater installation can dramatically reduce your monthly energy expenses.
If you're calling for heater repair more than once per season, you're likely spending more on fixes than a new installation would cost. It's time to upgrade.
Cold spots, temperature inconsistencies, or rooms that never get warm indicate your current system is undersized or failing. Professional heater installation solves this problem.
Banging, rattling, or screeching sounds—or unusual smells when your heater runs—signal serious mechanical problems. A new installation is often safer and more cost-effective than major repairs.
A cracked heat exchanger is a safety hazard that can leak carbon monoxide into your home. This critical component cannot be repaired—only complete heater replacement is safe.
Experiencing any of these issues? Don't risk your family's comfort and safety.

We provide professional heater installation throughout the Dallas-Fort Worth metroplex.
We offer complete heating solutions for your Dallas-Fort Worth home.
Most heater installations in Dallas-Fort Worth take 6-10 hours for a complete replacement, including removal of the old system. The timeline depends on system complexity, ductwork modifications, and whether any electrical or gas line work is needed. New construction installations may take 1-2 days. We'll provide an accurate timeframe during your free estimate.
The correct heater size depends on your home's square footage, insulation quality, ceiling height, window efficiency, and local climate. An oversized heater cycles on and off frequently, wasting energy and causing uneven temperatures. An undersized unit runs constantly and can't keep up. Our technicians perform Manual J load calculations to determine the perfect size for your specific Dallas-Fort Worth home.
Gas furnaces provide powerful heating and are often more cost-effective for primary heating in North Texas winters. Heat pumps offer both heating and cooling in one unit with excellent energy efficiency, making them ideal for our mild climate. Dual fuel systems combine both for maximum efficiency. We'll evaluate your home, utility costs, and comfort preferences to recommend the best option during your consultation.
Yes! LEX Air Conditioning offers flexible financing options with approved credit to make your heater installation affordable. We work with reputable lenders to provide competitive rates and payment plans that fit your budget. Ask about current financing promotions when you call for your free estimate.
AFUE (Annual Fuel Utilization Efficiency) measures how much of your fuel converts to heat. A 95% AFUE furnace converts 95% of fuel to heat, wasting only 5%. Standard furnaces are 80% AFUE, while high-efficiency models range from 90-98% AFUE. In Dallas-Fort Worth's climate, a 92-96% AFUE furnace offers the best balance of efficiency and value, significantly reducing your heating costs.
Absolutely! Modern high-efficiency heating systems use significantly less energy than older furnaces. If your current heater is 10-15 years old, upgrading to a new 95% AFUE furnace or high-efficiency heat pump can reduce your heating costs by 20-40%. The exact savings depend on your old system's efficiency, your new system's AFUE rating, and your home's insulation quality.
