Cooling and heating work for Plymouth homes
Certified Air Masters LLC is a family-run HVAC company owned by Frank and Ruthand Plymouth is squarely inside the area we cover every week. It sits between Apopka and Zellwood, close enough to Mount Dora and Tavares that we're usually out this way already — which means a call from a Plymouth address doesn't turn into a three-day wait for someone to drive out and look.
The work splits into two halves. The first is diagnosis and repair: a system that won't start, one that runs constantly without cooling, a breaker that keeps tripping, a drain line backing up, a condenser unit that's gone quiet, or a thermostat that reads nothing like the actual temperature of the house. The second is replacement — a full HVAC installation when the equipment has reached the end of its life and another repair would just be money spent on borrowed time.
We'll tell you honestly which of those two you're looking at. If a repair gets you several more seasons, that's what we recommend. If the fairer answer is that the system is finished, you'll hear that too, with the reasoning behind it rather than a sales pitch.
Hours, pricing and service area
We're open Monday through Friday, 8:00am to 5:00pmand Saturday from 8:00am to 1:00pm. We're closed Sunday. Booking a Saturday morning slot is often the easiest option for people who'd rather not take time off work, so it's worth asking about when you get in touch.
Pricing is handled the same way every time: nothing gets installed, replaced or dismantled until you've seen a written estimate and said yes to it. No verbal ballparks that grow by the end of the day.
Plymouth is one stop on a service area that runs across Orange, Lake, Osceola, Polk, Seminole and Sumter counties. Here's the full list of towns we cover:

A written estimate before anyone opens a wall
Here's what a job actually looks like from your side of it. You call or email and describe what the system is doing. We book a time inside our working hours and arrive in that window. We inspect the equipment, find the cause, and explain it in plain terms — including the part we think failed and why.
Then you get the estimate in writing. You read it, ask whatever you want to ask, and decide. If you approve it, we do the work. If you'd rather think it over or get a second opinion, that's a normal and reasonable thing to do, and you won't get a follow-up call every afternoon for a week.
You see the estimate in writing before we start. That's the whole policy — no work, no parts, no invoice you weren't expecting.
Because Frank and Ruth run the company themselves, the person setting the price is connected to the person doing the work. There's no commission structure pushing a bigger ticket, and no branch manager in another city to appeal to if something needs sorting out.
