Built by a local family.
Run differently on purpose.

We started HVAC Services Demo because the HVAC industry had a model problem. We left to fix it. Here's who we are and how we work.

Marcus and Elena Ramos, founders of HVAC Services Demo
Family-owned since 2011 Demo founders, Demo City

Thirteen years at a chain.
Then we walked out.

Marcus Ramos spent thirteen years as a senior technician at a large regional HVAC company. Elena ran their dispatch and customer service operations. Together they watched the same problems repeat every year: overbooked routes, techs rushed through jobs, commission structures that rewarded upselling over honest diagnosis.

"A homeowner would call in with a bad capacitor — a $200 fix — and the tech was pressured to quote the whole system because the commission was better," Marcus says. "We got tired of apologising for an industry that didn't need to work that way."

In 2011, they left. They bought one truck, hired one tech they trusted, and built a business on a simple rule: if we can repair it, we repair it. Fourteen years later, HVAC Services Demo runs eleven trucks across our service area. The rule hasn't changed.

Every HVAC Services Demo technician is a full W-2 employee. No subcontractors. No commission. No sales quotas. They're paid to fix your system correctly, and they're given the time and inventory to do it.

Three rules we've never bent once.

These aren't marketing copy. They're the three decisions we made in 2011 that shaped every hire, every truck, and every call since.

No commission, ever

Technicians are paid a flat salary. There is no financial incentive to recommend something you don't need. If we can repair it for $250, that's what we'll tell you.

Employees, not contractors

Every person who shows up at your door is a HVAC Services Demo employee — background-checked, drug-tested, NATE-certified, and covered by our $2M liability policy.

Quote first, work second

We diagnose, write a flat-rate quote, and wait for your approval. No work starts without your explicit sign-off. No surprises on the invoice.

The people who actually show up.

No subcontractors, no temp hires during peak season. These are the HVAC Services Demo team members who've been with us for years.

What we actually believe in.

01

Repair before replace

If a repair adds five years to your system, we say so and price the repair. We recommend replacement when the math actually justifies it — and we show you the math.

02

On time or it's free

If we give you a three-hour window and miss it without calling ahead, the trip charge is automatically waived. We've had to do it. It keeps us honest about scheduling.

03

Plain English, always

Your tech will explain exactly what's wrong, why it happened, and what the fix does — in language that doesn't require an HVAC license to understand. We don't use confusion as a sales tactic.

04

Smaller routes, more time

Most HVAC companies overbook their techs to maximise daily volume. We run fewer jobs per tech per day on purpose — so they're not rushing through your home to get to the next call.

05

Clean up on your way out

Every tech carries shoe covers, a drop cloth, and a vacuum. If we opened a panel, we close it. If we made a mess, we clean it. You shouldn't have to do anything after we leave.

06

Real people on the phone

Our after-hours line goes to a real HVAC dispatcher, not an answering service. If you call at 2am during a heat advisory, someone who knows our trucks and schedules picks up.

Fourteen years in our community.

2011

HVAC Services Demo opens with one truck

Marcus and Elena launch locally with a single service van, one full-time technician, and a waiting list of friends-of-friends who'd followed Marcus from his previous employer.

2013

First 1,000 customers

Word-of-mouth alone fills the schedule. HVAC Services Demo adds two more trucks and expands into surrounding communities. First time on local best-of lists — a ranking they've held every year since.

2016

Maintenance plan launches

The CoolCover plan is introduced at $189/year after customer feedback that seasonal maintenance was too easy to forget. It now has over 4,200 active subscribers.

2019

Voted #1 local HVAC company

Local readers name HVAC Services Demo the area's best HVAC company for the third consecutive year. Fleet expands to eight trucks serving all of our service area.

2021

Winter Storm Uri response

During the February freeze, HVAC Services Demo ran 24/7 operations for 11 straight days. Every tech worked voluntary overtime. No emergency pricing surcharges were applied to any customer.

2026

Eleven trucks, 1,847 Google reviews, 4.9 stars

HVAC Services Demo enters its fifteenth year as a top-rated independent HVAC service business. Still family-owned. Same rules. Same phone number.

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.
