What Actually Happens in Your House on Install Day
A stage by stage account of an AC changeout, from refrigerant recovery to the vacuum decay test and the county inspection, and what to watch for.

An Orlando air conditioner gets almost no time off. It cools from spring into late fall, often for hours a day, and every one of those hours wears on the drain line, the capacitor, and the coils. Up north, systems get a winter break. Here, the wear keeps adding up.
That's why a tune-up matters more here. At Jormechanical Air, our HVAC technicians use each visit to catch that wear while it's still small and simple to fix. You'll leave knowing what's healthy, what's wearing, and what can safely wait.

Many summer breakdowns start as something a tune-up would have caught. Here's each check and the problem it heads off, so you know exactly what you're paying for.
No water on the closet floor in July.
Drain line flushed. Algae loves a warm, wet drain line, and a Florida summer gives it both. Flushing it in spring keeps water moving out of the pan, so the overflow switch doesn't shut your cooling off on a hot afternoon.
The outdoor unit starts on the first try.
Capacitor tested. Capacitors rarely fail on a mild day. A meter shows how much charge yours still holds, so a weak one gets replaced now instead of during the first heat wave.
The house cools down in less time.
Coils cleaned. Your indoor coil pulls heat out of the house, and the outdoor coil sends it outside. Clear the pollen and dust off both, and the system reaches your setting without the extra run time.
A slow leak shows up in April, not August.
Refrigerant checked. Gauges tell us whether the charge matches what your system was built for. A low reading now is a leak you can fix calmly, long before it costs you cooling.
Nothing buzzes or smells hot at startup.
Wiring tightened. Months of heat and nonstop cycling work terminals loose. A loose connection runs hot, so tightening it now protects the contactor and motors from damage later.
Every room gets its share of cold air.
Airflow and thermostat tested. Air has to move freely past the filter and blower to reach the far bedrooms. Then the thermostat gets checked, so cooling starts and stops exactly when it should.
Want every item on that list checked on your system? Book a tune-up, and our HVAC technicians will walk you through what they found before they leave. If a part needs repair, you'll see the price first and decide whether it happens that day or on another visit.

Of everything your air conditioner can cost you in a year, a tune-up is the smallest line. Most repairs we make run a few hundred dollars, and replacing a burned-out compressor can climb toward $4,000, often in the hottest week of summer.
A tune-up catches many of those problems while they're still a worn part instead of a dead system. You'll know the tune-up price before any work starts, and if the visit finds a part that needs replacing, that repair is priced separately and waits for your approval.
A tune-up keeps a working system working, and a repair visit fixes one that has already stopped. Tell us what you've noticed, and we'll book the one that fits. If our technician finds it's the other kind of visit, you'll hear that on the spot, not a sales pitch.
| Tune-up | Repair visit | |
|---|---|---|
| Book it when | Your system runs fine and it's been six months or more | Something changed, like air that isn't cold, a puddle, or a sound you haven't heard before |
| What the visit is for | Cleaning, testing, and adjusting the whole system while it still works | Tracing one symptom back to the part that failed |
| Best time to book | Spring and fall, before the peak seasons start | The day you notice the change |
| What you leave with | A list of what was checked and what to plan for | The fault fixed, or your options explained in plain words |
| If it turns out to be the other one | We switch to the right visit, and you decide when | Same. Nobody sells you a visit you don't need |

Carrier, Trane, Lennox, Goodman, Rheem, or Daikin, whatever name is on your outdoor unit, the checklist stays the same. We service all major brands, so you don't need to track down the company that put your system in.
You're letting a company into your home every spring and fall, so check its record first. We've been BBB accredited since April 2025 with an A+ rating, and the profile is public. Read it before you book.
Here's what a visit looks like from booking to the final check.
Call or book online and tell us roughly how old your system is and when it was last serviced. Mention any problems you've noticed, even small ones.
Our technician works through every item on the checklist, indoors and out. Watch and ask questions, or carry on with your day while the work gets done.
Before we leave, you get a plain-words rundown of what's healthy and what's wearing. Any repair comes with a price first, and it only happens with your okay.
Ask us to put you on a twice-a-year schedule, and we'll call when your next tune-up comes due. That keeps the spring and fall rhythm going without you tracking dates.
Maintenance is the one service call you get to plan, so plan it for a day that suits you. Tell our office your system's age and anything odd you've noticed, and you'll get a firm arrival window. Most tune-ups land that same week.
Share the system's rough age, the last time it was serviced, and anything odd, like a new noise or a room that runs warm. It helps our technician plan the visit.
Yes. We book tune-ups Monday through Saturday, and the office answers from 7:30 a.m. each of those days. Share your work hours when you call, and we'll find a window that doesn't cost you a full day.
From our office north of downtown Orlando, tune-up visits reach Orange, Seminole, Volusia and Osceola counties. Wherever you are on the map, you get the same checklist, the same testing, and the same plain-words rundown.

Some upkeep takes five minutes and no tools, like swapping a filter or checking where the drain line empties outside. Our blog walks you through those small habits, so your system stays healthier between visits.

The refrigerant rule, the HFC phasedown, SEER2 standards and metals tariffs, each explained by name, and which of them are permanent.
Yes, and here is which permit, who may pull it, whether the county or the city issues it for your address, and what unpermitted work costs you later.
Maintenance means letting the same company into your home year after year, so trust matters. These Google reviews show how homeowners felt about the people working on their systems.
Absolutely great service. Replaced my AC unit 2 years ago. Very personal-able. Ive been using annually to service my AC ever since
He arrived promptly at the agreed time, communicated clearly throughout the visit, and completed all the necessary work to a high standard.
Worked very clean and cleaned up after.
They came fast, fixed my AC, and didn't talk over my head.

Yes, with care. Switch off power at the outdoor disconnect, clear away leaves and debris, and rinse the fins gently with a garden hose. Skip the pressure washer, since it can flatten the thin metal fins.
It can. Many manufacturer warranties require the equipment to be properly maintained, and some ask for proof. Keep each tune-up invoice with your warranty papers, so the service history is ready if a claim comes up.
Mold or mildew on the indoor coil, in the drain pan, or in a drain line that holds water is the usual cause. Cleaning those parts is often what clears the smell.
Most take about an hour to an hour and a half. Heavy dirt on the coils or a stubborn drain line clog can add time, and so can a system that's hard to reach in an attic.
Yes, or have another adult there. The technician needs to reach the indoor unit and thermostat, and you'll want to hear what was found before the visit ends.
