Answering Your Questions

Frequently Asked Questions

Check your filter monthly and replace every 30-90 days depending on filter type, pets, and allergies. A dirty filter restricts airflow, increases energy bills, and accelerates system wear. It's the easiest thing you can do to keep your system running well.

Proper sizing requires a professional load calculation - not just square footage. We assess your home's insulation, windows, ceiling height, orientation, and more to recommend the right equipment. An oversized system cycles too frequently and won't control humidity; an undersized one can't keep up on hot days.

With proper maintenance, air conditioners typically last 15-20 years, furnaces 20-25 years, and heat pumps 12-15 years. The East Texas humidity and heat put extra stress on equipment, making regular maintenance especially important for maximizing lifespan.

Yes. We respond to urgent heating and cooling situations throughout Tyler and East Texas. Call 903-393-1044 when you need help fast - we understand that HVAC emergencies don't wait for business hours.

We're an American Standard Customer Care Dealer, known for reliable, high-efficiency equipment. We also install Samsung mini-splits and Active Gold by DustFree air quality products. These are brands we trust and stand behind.

Absolutely. We have extensive experience with mobile and modular home HVAC systems, including package units, specialized ductwork, and equipment rated for manufactured housing. Many HVAC companies won't touch mobile homes - we specialize in them.

Regular maintenance, proper insulation, and upgrading to high-efficiency equipment all help. We can assess your current system and recommend improvements that fit your budget. Sometimes a simple tune-up makes a noticeable difference; other times, a system upgrade pays for itself in savings.

A heat pump moves heat instead of generating it, providing both heating and cooling in one system. Furnaces burn fuel (usually natural gas) to create heat. Heat pumps are more efficient in mild climates like East Texas, while furnaces excel in extreme cold.

Yes, we've partnered with Synchrony to offer flexible financing options for qualified customers. This makes it easier to invest in quality equipment without a large upfront payment. Ask about current promotions when you call.

Consider replacement if your system is over 15 years old, needs frequent repairs, struggles to maintain temperature, or uses R-22 refrigerant (which is being phased out). We provide honest assessments and never push unnecessary replacements - we'll tell you what we'd do if it were our house.

SEER (Seasonal Energy Efficiency Ratio) measures air conditioning efficiency - how much cooling you get per unit of electricity. Higher SEER means lower operating costs. Modern systems range from 14-22+ SEER, with higher ratings saving more on energy bills over time.

Yes. Our Priority Maintenance Plans include seasonal tune-ups, priority scheduling, and discounts on repairs. Regular maintenance prevents breakdowns, extends equipment life, and keeps your warranty valid. It's the best way to protect your investment.

Common causes include low refrigerant (often from a leak), dirty coils, thermostat issues, or a failing compressor. Some fixes are simple; others require professional attention. Call us at 903-393-1044 for a diagnosis - we'll tell you exactly what's wrong before doing any repairs.

We install Active Gold by DustFree air purification systems, UV lights, humidifiers, dehumidifiers, and high-efficiency filters. These solutions help with allergies, asthma, and overall home health by removing or neutralizing airborne contaminants.

Yes, we're fully licensed (TACLB#39819E) and insured for your protection. We're also BBB accredited and committed to honest, ethical business practices. When we work on your home, you're covered.
