About HVAC Services Demo

Built by an local family. Run differently on purpose.

HVAC Services Demo was founded by Marcus and Elena Ramos after thirteen years working for one of the biggest HVAC chains. They left because the model was broken — overbooked techs, surprise pricing, sales targets that pushed unnecessary system replacements.

We do this differently. Smaller routes, fewer trucks, more time per call. Every HVAC Services Demo tech is a full employee — never subcontracted, never paid on commission. They're here to fix your system right, not to upsell you.

If we can repair it, we repair it. If you genuinely need a new system, we show you the math first. And if we say we'll be there at three, we're there at three — or we knock the trip charge off your bill.

  • NATE-certified technicians
  • Background-checked staff
  • Up-front flat-rate pricing
  • No commission, no upsells
  • $2M insurance coverage
  • 100% satisfaction guarantee
Instant Estimate

AC died on a Saturday in July. Called at 9am, tech named David was at our door by 10:40 with a working part on the truck. Fixed in an hour. Quote was lower than the bigger company that quoted me last year for the same kind of repair.

What I liked most: the tech told me my system had another five years easy. The previous company tried to sell me a $9,000 replacement. HVAC Services Demo charged me $340 for the actual fix. Honest people doing honest work.

On the maintenance plan for two years now. They show up exactly when they say they will, find small issues before they become expensive ones, and the techs always wear shoe covers in our house. Small thing — says everything.

FAQ

Things people actually ask.

Real answers to the questions local homeowners ask us every week. If yours isn't here, just call — we'll tell it to you straight.

Call (555) 010-0100
  • Most repairs land between $180 and $650, depending on the part and labor. Capacitor and contactor swaps are typically $180-$280. Refrigerant leaks and compressor work run higher. We give you a flat-rate written quote before any work starts, and we don't charge for the diagnosis if we can't fix it the first time.
  • Average response across our service area is 90 minutes during business hours. For true emergencies — no AC during a heat advisory, no heat in a freeze — we dispatch the closest tech immediately. After hours and weekend calls go to a real on-call dispatcher, not a service. If you don't get a callback within 5 minutes, something has gone wrong.
  • Yes. We partner with Synchrony and Wells Fargo for installation financing on systems over $4,500. Terms range from 12 months no-interest to 84 months at competitive rates. We can run a soft credit check that won't affect your score during your in-home estimate, and you'll have your options before we leave.
  • Carrier, Trane, Lennox, Mitsubishi, and Goodman. We're certified to install and warranty all five. We don't push one brand over another — we recommend based on your home, usage patterns, and budget. We'll explain the trade-offs in plain English during the estimate.
  • For most homes, yes. The plan is $189 a year and covers two visits — spring AC, fall heating. You also get priority dispatch, 15% off any repairs, and waived after-hours fees. The math: if we catch one mid-sized issue early, the plan pays for itself. About 70% of plan holders avoid at least one major repair we'd have otherwise had to make in a panic.
  • Every HVAC Services Demo tech is licensed by the Texas Department of Licensing and Regulation, NATE-certified, EPA-certified for refrigerant handling, and background-checked. The company carries $2 million in general liability insurance and full workers' comp. Our state license number is Licensed (demo) — listed in the footer of every page on this site.
