Signs Your AC Needs Professional Attention

Don't wait until your system fails completely. Watch for these warning signs.

Warm Air Blowing

If your AC runs but only blows warm or lukewarm air, you may have a refrigerant leak, compressor issue, or frozen coils.

Unusual Noises

Grinding, squealing, banging, or rattling sounds indicate mechanical problems that will worsen without repair.

Water Leaks

Water pooling around your indoor unit signals a clogged drain line, cracked pan, or frozen evaporator coil.

Rising Energy Bills

A sudden spike in electricity costs often means your AC is working harder than it should due to underlying issues.

Frequent Cycling

Short cycling — turning on and off repeatedly — wastes energy and indicates thermostat, refrigerant, or electrical problems.

Strange Odors

Musty smells suggest mold growth; burning odors could indicate electrical issues that pose a fire hazard.

Air Conditioning FAQs

Common questions about AC services in Dallas-Fort Worth.

How often should I have my AC serviced?

We recommend professional AC maintenance at least once a year, ideally in spring before the cooling season begins. This tune-up includes cleaning coils, checking refrigerant levels, inspecting electrical connections, lubricating moving parts, and testing overall system performance. Regular maintenance prevents 95% of breakdowns, improves efficiency, and extends your system's lifespan. Our Cool Club members receive two tune-ups per year — one for AC in spring and one for heating in fall.

How long does an AC system last in Texas?

In the Dallas-Fort Worth area, air conditioning systems typically last 12-15 years with proper maintenance. Texas heat puts more stress on cooling systems than milder climates, so systems here often have shorter lifespans than the national average. Factors affecting longevity include maintenance frequency, quality of installation, system quality, and how hard the system works (home insulation, sun exposure, etc.). Well-maintained premium systems can last 18-20 years, while neglected systems may fail in 8-10 years.

What size AC do I need for my home?

Proper AC sizing requires a professional load calculation that considers your home's square footage, insulation, windows, orientation, ceiling height, and other factors. An undersized system won't cool adequately; an oversized system short-cycles, wastes energy, and fails to dehumidify properly. As a rough guide, most DFW homes need 1 ton of cooling capacity per 500-600 square feet, but this varies significantly. Our technicians perform Manual J load calculations to ensure you get the right size system for optimal comfort and efficiency.

How much does a new AC system cost?

New AC system costs in DFW typically range from $5,000-$15,000+ depending on system size, efficiency rating (SEER), brand, and installation complexity. Basic single-stage systems start around $5,000-$7,000, while high-efficiency variable-speed systems can exceed $12,000-$15,000. The investment pays off through lower energy bills, fewer repairs, better comfort, and increased home value. We offer financing options to make upgrades affordable, and we'll always provide multiple options at different price points.

What's the difference between SEER and SEER2?

SEER (Seasonal Energy Efficiency Ratio) measures AC efficiency — higher numbers mean greater efficiency. As of January 2023, the industry transitioned to SEER2, which uses updated testing procedures that better reflect real-world conditions. SEER2 ratings appear about 4-5% lower than equivalent SEER ratings due to the stricter testing, not because systems are less efficient. The current minimum in Texas is 14.3 SEER2 (equivalent to 15 SEER). Higher-efficiency systems (18+ SEER2) cost more upfront but save significantly on energy bills over time.

Do you offer emergency AC service?

Yes, we provide 24/7 emergency AC service throughout the Dallas-Fort Worth metroplex. We understand that AC failures don't wait for business hours, especially during brutal Texas summers. When you call our emergency line, we prioritize dispatch to get you cool as quickly as possible. Emergency service is available nights, weekends, and holidays. Response times vary by location and demand, but we typically arrive within 1-2 hours for true emergencies.

Should I repair or replace my AC?

Consider replacement if: your system is 12-15+ years old, repair costs exceed 50% of replacement value, you're facing frequent breakdowns, your energy bills keep rising, or the system uses R-22 refrigerant (phased out and expensive). Consider repair if: the system is under 10 years old, the repair is relatively minor, and the system has been well-maintained. Our technicians provide honest recommendations based on your specific situation — we never push unnecessary replacements.

What can I do to keep my AC running efficiently?

Homeowners can take several steps: change air filters monthly during cooling season (or per manufacturer recommendation), keep outdoor units clear of debris and vegetation (2+ feet clearance), ensure vents aren't blocked by furniture or curtains, keep blinds closed during peak sun hours, maintain consistent thermostat settings, and schedule professional maintenance annually. These simple practices reduce strain on your system, lower energy bills, and help prevent breakdowns.

— James M., McKinney, TX

"After bad experiences with other HVAC companies, LEX restored my faith. They were honest about what my 12-year-old system needed, didn't try to upsell me on a new unit, and the repair has held up perfectly for two years now. Genuine integrity."
