Professional Furnace Maintenance to Keep Your Home Warm All Winter Long
When winter arrives in Dallas-Fort Worth, the last thing you want is a furnace breakdown in the middle of a cold snap. Regular heater tune-ups are your best defense against unexpected heating failures, high energy bills, and uncomfortable indoor temperatures. At LEX Air Conditioning and Heating, we've been keeping North Texas homes warm and comfortable since 2004 with comprehensive heating maintenance services you can depend on.
Our preventative maintenance program is designed to catch small issues before they become expensive repairs, improve your system's efficiency to lower your utility bills, and extend the lifespan of your heating equipment. Whether you have a gas furnace, heat pump, or electric heating system, our licensed technicians have the expertise to keep it running at peak performance throughout the heating season and beyond.
Our comprehensive heating maintenance service covers every critical component of your system.
We thoroughly inspect and clean your furnace burners to ensure optimal combustion, improve efficiency, and prevent dangerous carbon monoxide buildup.
Clean or replace air filters to maintain proper airflow, improve indoor air quality, and prevent unnecessary strain on your heating system.
Test all electrical connections, capacitors, relays, and circuit boards to prevent unexpected failures and ensure safe operation of your heater.
Verify thermostat accuracy and functionality to ensure your home maintains the perfect temperature without wasting energy.
Test all safety mechanisms including limit switches, flame sensors, and pressure switches to ensure your heating system operates safely.
Measure voltage, amperage, temperature rise, and overall system performance to identify any issues and optimize efficiency.
Don't ignore these warning signs — early detection can save you money and prevent bigger problems.
If your heating costs have increased without explanation, your system is likely working harder than it should due to lack of maintenance.
Some rooms too hot, others too cold? This could indicate airflow problems, ductwork issues, or a system that needs professional attention.
Banging, rattling, squealing, or grinding sounds are never normal and often indicate mechanical problems that need immediate attention.
If your heater turns on and off more frequently than normal, it could be struggling due to dirty filters, faulty sensors, or other issues.
A yellow or flickering flame instead of steady blue indicates incomplete combustion and potential carbon monoxide risk. Call us immediately.
Even if everything seems fine, annual maintenance is essential to prevent problems and maintain efficiency. Don't wait for a breakdown.
Noticing any of these issues? Don't wait until it becomes an emergency.

We recommend scheduling a professional heater tune-up once a year, ideally in the fall before the heating season begins. Annual maintenance helps prevent breakdowns, improves efficiency, and extends the life of your heating system. If you have an older system or use your heater heavily, you may benefit from more frequent service.
Our comprehensive tune-up includes inspecting and cleaning burners, checking and replacing air filters, testing all electrical components and safety controls, calibrating your thermostat, measuring system performance, lubricating moving parts, and checking for gas leaks or carbon monoxide issues. We provide a detailed report of our findings and recommendations.
Our standard heater tune-up typically costs between $89-$149 depending on your system type. However, the best value is our Cool Club maintenance plan, which includes both annual heating and cooling tune-ups for one low price. Call (972) 466-1917 for current pricing and specials.
While no service can guarantee 100% prevention, regular tune-ups significantly reduce the likelihood of unexpected breakdowns. During maintenance, our technicians identify and address small issues before they become major problems. Statistics show that properly maintained heating systems have 95% fewer emergency breakdowns than neglected systems.
Yes! A well-maintained heater operates more efficiently, which translates to lower energy costs. Dirty filters, worn components, and poor calibration can cause your system to work harder and use more energy. Our customers typically see 10-15% reduction in heating costs after a professional tune-up, and those savings continue throughout the heating season.
Absolutely! Many heating problems develop gradually and aren't noticeable until they cause a breakdown. Regular maintenance catches these issues early, maintains manufacturer warranties (which often require annual service), ensures safe operation, and keeps your system running efficiently. Think of it like regular oil changes for your car — prevention is always cheaper than repair.
