What Our Customers Say

Summit replaced our entire HVAC system in one day. The technician walked me through every step, the price matched the quote exactly, and our energy bill dropped $140 the first month. I've recommended them to four neighbors already.

AC stopped working on a 98-degree Saturday. Called Summit and had a tech at my door within two hours. He diagnosed the issue, had the part on his truck, and the system was running within the hour. Absolutely no after-hours upcharge either.

The Total Comfort plan has paid for itself twice over. Last spring they caught a cracked heat exchanger during our annual tune-up — would have been a carbon monoxide situation. These guys take the job seriously. Worth every penny.

Used the $0 down financing and got a brand new high-efficiency system with a smart thermostat. The whole process — from quote to installation — took less than a week. My old unit cost me a fortune in repairs. I wish I'd done this years ago.

FAQ

Questions We Hear Every Day

Twice per year — once in spring for your air conditioner and once in fall for your furnace. Regular tune-ups extend equipment life by 3–5 years, maintain manufacturer warranties, and catch problems before they become expensive breakdowns. Our membership plans make this effortless and affordable.

Most residential system replacements are completed in one day — typically 4–8 hours. We'll provide a specific timeline in your written estimate. Complex projects involving ductwork modifications may take two days. We won't leave your home without working heat or AC.

We're a factory-authorized dealer for Carrier, Lennox, Trane, Rheem, and Bryant. We also service all major brands including Goodman, York, Ruud, American Standard, and most others. Our trucks carry over 2,000 commonly needed parts to resolve most repairs in a single visit.

A general rule: if your system is over 10–12 years old and the repair exceeds $1,000, replacement is usually more economical. A new high-efficiency system typically saves 25–40% on energy bills. We'll give you an honest comparison of repair vs. replacement costs with no pressure either way.

Yes — genuine 24/7 emergency service with a live dispatcher (not an answering machine). We maintain on-call technicians every night, weekend, and holiday. We do not charge overtime premiums for after-hours calls. Members on the Total Comfort or Ultimate Comfort plans receive priority dispatch.

We offer multiple financing options through GreenSky and Wells Fargo Financial. Applications take about 60 seconds and use a soft credit pull that won't impact your score. Most customers are approved within minutes. Options range from 0% for 18 months to extended low-payment plans up to 10 years.

Our 10-year labor and parts warranty covers any defect in workmanship or premature part failure related to our installation for a full decade. This is in addition to the manufacturer's equipment warranty (typically 5–10 years on parts). Combined, you're protected for up to 10 years on virtually everything.

Proper sizing requires a Manual J load calculation that accounts for your home's square footage, insulation, window count and orientation, ceiling height, and local climate. We perform this calculation on every project at no charge. Oversized and undersized systems both cause problems — correct sizing is critical.
