Four kinds of building, four ways to fail

HVAC for apartments, restaurants, retail and medical offices

A rooftop unit over a dining room and a split system in an exam room break in different ways, and a different person has to make the call on each. Pick the kind of building you look after and we'll talk about yours specifically.

Standard, before you ask

What every commercial customer gets

Facilities managers ask the same questions in the first five minutes of a call. The answers are below, so the first call can be about your building instead.

Response: You hear back within the hour; We call or text with a real arrival time and the name of whoever is coming, so you aren't left waiting on a window that runs all afternoon.
After hours: Emergency calls until 11 PM; Call the same number and you reach the same people. Tell us it's a business and what the unit serves, and we'll tell you when we can be there.
Quotes: In writing, before any work; You see the number and approve it in writing before anything gets replaced.
Scheduling: Planned work around your hours; We can come early, late or on a weekend when the work is booked ahead, so it happens while the building is quiet.
Accounts: Several properties, one account; You get one point of contact and one invoice, with every address listed on it.
Insurance: Certificate of insurance on request; If a landlord or general contractor wants a certificate of insurance before we go on the roof, mention it when you book. For permitted commercial work, it's already on file with the city.
Reporting: A report after every visit; After each visit you get a written note of what we found, what we did and what to keep an eye on.
Tenants: Tenants told before we're in their space; Whoever's in the suite knows when we're coming and what we'll be doing, before we knock.
Who shows up: Owner-run, based in Winter Garden; The person you reach works on the equipment, and there's no call center between you and the answer.
Maintenance: Plans that put the equipment on a schedule; What a visit covers and how often it comes is on the plans page. Maintenance plans

If you need something that isn't on the list, ask when you request the visit. If it isn't something we do, we'll tell you.

From the rooftop to the thermostat

Rooftop package units

We repair them on the roof, replace them when they're worn out, and maintain them so that day comes later.
Split systems

Condensers sit on the ground or a wall, with air handlers in a closet or ceiling. We service them in offices, exam rooms and back-of-house spaces.
Thermostats & controls

We install and repair programmable and smart thermostats, and set schedules so an empty building doesn't cool like a full one.
- Repair
- Installation & replacement
Indoor air quality

We handle filtration, humidity and duct cleaning in rooms where the air matters to the business, like waiting rooms, dining rooms and shop floors.

A number before any work

How a commercial HVAC call works

A commercial call has four steps. At each one you know what's been decided and what comes next, and you decide it with the person who does the work.

The site walk We come and look at the equipment: the units, what they serve, what's been failing, and how the building runs its day. It helps if whoever signs off on the work can be there too.
A number, in writing The quote says what's wrong, what it takes to fix and what it costs, plus our advice on repair or replace if that's the question. You approve it before anything gets replaced.
Scheduled around your hours We can come early, late or between services, whenever the building is quiet. The people in it are told when to expect us.
A report after the visit You get a written note of what we found, what we did and what to watch. Every visit is logged against the equipment, so the next call starts with its history.

A rooftop unit never picks a quiet week to fail

Commercial HVAC maintenance plans

A plan puts every unit you're responsible for on a calendar. Each one is checked and cleaned before the hot season, and the part that's wearing out gets found before it fails.

Before the season The spring visit finds the weak capacitor and the slow leak, so the unit is ready for the first 95° afternoon.
Downtime with a date A planned visit happens on a date you choose. A breakdown picks its own time, and it's usually when the building is full.
The equipment on file Every unit and every visit is logged against the building. When something does fail, we start from that history instead of walking the roof to see what you have.

Questions

Commercial HVAC questions and answers

These are the questions we hear most from commercial customers, answered the way we’d answer them on the phone.

How fast do you respond to a commercial call?

You hear back within the hour with the name of whoever is coming and when they'll arrive. Emergency calls are answered until 11 PM.

Do you work on rooftop units?

Yes, we repair, maintain and replace rooftop units. Rooftop package units are most of what sits on a commercial roof in West Orange County. We also work on the split systems inside the building and the thermostats and controls that run all of it.

Do we get a quote before any work starts?

Yes, you get the quote in writing. We explain what we found and write up what it takes to fix and what it costs. Nothing is done until the person who signs off has approved it, whether that's you, an owner, a board or a landlord.

Can you do the work when the building is closed?

Yes, planned work can be scheduled outside your hours: early, late or on a day you're closed, agreed with you first. Emergency calls are answered until 11 PM.

Do you offer maintenance plans for commercial buildings?

Yes, we offer maintenance plans for commercial buildings. A plan puts the visits on a calendar before the season instead of after a failure, and it keeps every unit's history on file. What a plan covers depends on the building and its equipment, and the plans page has the detail.

Can you handle several buildings or stores for us?

Yes, several buildings can sit under one account, with one point of contact, one invoice and every unit on file. Tell us how many buildings you have and where they are, and we work through them starting with the ones causing the most trouble.

Can you provide a certificate of insurance?

Yes, we send a certificate of insurance on request before the first visit. Landlords and general contractors usually ask for one before roof access, so mention it when you call and it will arrive ahead of us.
