Air Conditioning

How do I know if my AC needs repair or replacement?

If your system is under 10 years old and the repair is minor — a capacitor, a refrigerant leak, a clogged drain line — repair is usually the smart call. If your AC is 12–15+ years old, needs frequent repairs, or the repair quote approaches half the cost of a new system, replacement typically saves you more over time. We give you an honest assessment with both options priced out, and estimates are always free.

Why is my AC running but not cooling the house?

The most common culprits are a dirty air filter, low refrigerant from a leak, a frozen evaporator coil, or a failing compressor. Some of these are quick fixes; others need a trained technician with gauges and diagnostic tools. Turn the system off so you don't damage the compressor, then give us a call — we offer same-day service across Round Rock and the Austin metro.

How often should I replace my air filter?

Every 1–3 months for standard 1-inch filters, and every 6–12 months for thicker media filters. Homes with pets, allergies, or heavy use should change filters more often. A clogged filter is the #1 cause of avoidable AC breakdowns we see in Central Texas summers.

What size AC unit does my home need?

It depends on square footage, insulation, window exposure, ceiling height, and ductwork — not just a rule of thumb. An oversized unit short-cycles and leaves your home humid; an undersized one runs constantly and still can't keep up in a Texas July. We perform a proper load calculation before recommending a system, and as Trane and Daikin factory-trained installers we'll match you with equipment that fits your home and budget.

Service FAQs

Heating

My furnace is blowing cold air — what should I check first?

Check the thermostat is set to heat and the fan is on auto (not on), then check the air filter. If both look fine, the issue may be the igniter, flame sensor, or gas supply — those need a professional. We diagnose and repair all major furnace brands and offer same-day appointments.

How long does a furnace or heating system last in Central Texas?

Gas furnaces typically last 15–20 years here, and heat pumps 10–15 years, since our heating season is short but our cooling season works the same equipment hard. Annual maintenance is the single biggest factor in reaching the high end of that range.

Should I repair my old heater or upgrade to a heat pump?

For many Central Texas homes a heat pump is the most efficient choice — it heats and cools with one system, and our mild winters are exactly what heat pumps are designed for. If your furnace or AC is nearing end of life, upgrading both to a single heat pump system often lowers your utility bills. We'll run the numbers with you, including available financing.

Service FAQs

Heat Pumps & Ductless Mini-Splits

Do heat pumps work well in Texas heat?

Yes — modern heat pumps from Trane and Daikin are engineered for exactly our climate. In summer a heat pump cools just like a high-efficiency AC; in winter it heats far more efficiently than electric resistance heat. That dual role makes them one of the best value systems for Round Rock and Austin-area homes.

Where do ductless mini-splits make the most sense?

Garage conversions, home offices, additions, casitas, sunrooms, and any room your central system can't keep comfortable. Mini-splits need no ductwork, run extremely quietly, and let you condition only the space you're using. We're Daikin factory-trained — sizing and placement make all the difference with ductless.

How long does a mini-split installation take?

Most single-zone installations are done in one day. Multi-zone systems usually take one to two days depending on line-set runs and the number of indoor heads. We'll give you a firm timeline with your free estimate.

Service FAQs

Air Quality & Ductwork

Why is my home so dusty even though I change the filter?

Leaky return ducts are a common cause — they pull dust from your attic straight into the system and distribute it through the house. Duct sealing, duct cleaning, or upgraded filtration can make a dramatic difference. We can inspect your ductwork and show you exactly what's happening.

Do air purifiers and UV lights actually help with allergies?

For Central Texas allergy seasons — cedar fever especially — whole-home filtration and purification can genuinely help. Media filters capture pollen and dust, while UV and ionization systems address mold, bacteria, and odors at the coil. We'll recommend options based on your home and symptoms, not a one-size-fits-all package.

How often should ducts be cleaned?

There's no fixed schedule — it depends on pets, renovations, and how well-sealed the ducts are. If you see visible dust blowing from registers, notice musty smells, or just finished construction work, it's worth an inspection. We'll tell you honestly whether cleaning is needed.

Service FAQs

Maintenance & Tune-Ups

View Page
How often should my HVAC system be serviced?

Twice a year: a cooling tune-up in spring before the heat arrives, and a heating check in fall. Regular maintenance catches small issues before they become summer breakdowns, keeps your energy bills down, and protects your manufacturer's warranty. Our maintenance plan takes care of the schedule for you.

What's included in a maintenance plan?

Seasonal tune-ups, priority scheduling, and member discounts on repairs. It's the most cost-effective way to extend the life of your system — especially in Central Texas where air conditioners work overtime half the year. Visit our Maintenance Plan page or call us for details.

Is a tune-up really worth it if my system seems fine?

Yes — most July breakdowns we respond to had warning signs a spring tune-up would have caught: weak capacitors, low refrigerant, dirty coils. A tune-up costs a fraction of an emergency repair, and it keeps your system running at the efficiency you're paying the electric bill for.
