Johns Creek has a substantial base of commercial tenants, property managers, and landlords keeping multi-unit properties running. When a system goes down in an occupied building, the call has to move fast and the repair has to hold. We handle commercial heating and cooling repair, maintenance, and system replacement across Johns Creek and work around tenants and business hours so the property stays functional while the work gets done.
Homeowners in Johns Creek call us for the same range of work: AC repair, furnace service, heat pump installation, ductwork, thermostats, and full system replacements when a unit has run its course. Whatever the property, the process starts the same way. You call, we scope the job on the phone, and nothing is scheduled until the price and the scope are both clear.
Call (770) 635-5441 between 7:30 AM and 10:00 PM, any day of the week.
A diagnostic visit in Johns Creek starts before anything is opened up. The technician who comes out asks what the system has been doing, when it started, and whether anything changed beforehand. That conversation shapes what gets checked first and keeps the visit focused on the actual fault rather than a checklist that starts from scratch every time.
From there, the inspection moves through the components most likely to cause that specific symptom. Refrigerant pressure, electrical connections at the unit, evaporator coil condition, airflow through the air handler, ignition components on a furnace. The goal is a clear picture of what is wrong before any repair is quoted. You hear what was found, what fixing it involves, and what it costs. Nothing moves forward until that conversation happens.
Work is carried out to code on every job. That is not a selling point. It is how the work has to go.
Getting your comfort back is easier than you think, and pricing is part of that. The rate is confirmed on the call before anything is scheduled. What the fault turns out to be, how accessible the component is, and whether a repair makes more sense than a replacement are the things that move a quote in one direction or another.
A refrigerant leak diagnosis is a different scope from replacing a blower motor, and both are different from a full system swap. Installation work comes with a written scope so you know exactly what is covered before the job starts. Ask what the visit covers and you get a straight answer.
The question of repair versus replacement comes up most often on equipment that has been running for a number of years and has needed more than one fix in recent seasons. We walk through both options when replacement is a reasonable path, so the decision is yours to make with a clear picture of what each involves.
A ductless mini-split system makes sense when the space being conditioned was never part of the original HVAC plan. Converted garages, sunrooms, additions, finished basements, and upper floors that run consistently warmer than the rest of the house are the situations where a mini-split earns its place. Running new ductwork into those spaces is often more disruptive and more expensive than the alternative.
A single-zone mini-split handles one space with one indoor unit and one outdoor unit. A multi-zone setup runs several indoor units off a single outdoor unit, which makes it practical for a home that has two or three spaces that need independent control. Both options handle heating and cooling through the same system.
Mini-split installation covers the outdoor unit, the indoor air handler, the refrigerant line set, and the controls. For a repair call on an existing ductless system, the diagnostic looks at the refrigerant circuit, the air handler, and the control board. The visit follows the same process as any other HVAC call: the fault is identified before any repair is quoted.
One call gets the whole thing moving.
A seasonal maintenance visit is more specific than the phrase suggests. On the cooling side, the technician checks refrigerant levels, inspects the evaporator coil for buildup that restricts heat transfer, cleans the condenser coil, tests the capacitor and contactor, and confirms airflow through the air handler. On the heating side, the visit covers the heat exchanger, burner operation, ignition components, and the flue. The thermostat calibration gets checked on both.
The point of scheduling before the season starts is catching the component that is wearing out before it fails during the stretch when the system runs hardest. A capacitor that is reading low in April is a much smaller problem than one that fails in late July. Scheduling is booked around your calendar, not ours.
HVAC service booked around your schedule is one of the practical things we do that makes a difference when a property manager is coordinating around tenants or a homeowner cannot be flexible about timing.
A home that heats and cools right is a comfortable home, and when that breaks down in the middle of a Georgia summer or a cold January stretch, waiting is not an option. We take emergency no-heat and no-cool calls every day from 7:30 AM to 10:00 PM. When you call, the job gets scoped on the phone so the visit is set up correctly before anyone heads out.
For commercial properties and occupied rentals, we work around the hours and the people already in the building. A retail space that has to stay open, a multi-unit building with tenants on site, a business that cannot shut down for a full day: the scheduling conversation covers all of that. You tell us what the constraints are and we work within them.
The person who answers the phone can walk through the symptoms with you. That conversation shapes the visit before it starts, which keeps the time on site focused and the disruption to the property minimal. What each job covers is written out on the page covering our heating and cooling services.
When a room is added to a home, the existing duct system was sized for the original footprint. The new space often ends up underserved: it takes longer to reach temperature, or the system runs longer trying to compensate. Ductwork design for an addition means calculating the load the new space adds and routing supply and return air correctly so the whole system stays balanced.
Low airflow at a register can come from a blocked duct, a disconnected joint pushing conditioned air into an attic or crawl space, a clogged filter restricting the air handler, or a blower motor that is losing capacity. The diagnostic checks the whole path from the air handler to the vent rather than treating the symptom at the register.
A furnace that starts and then shuts back down is often a flame sensor issue: the sensor does not confirm the burner is staying lit and shuts the system off as a precaution. A furnace that runs but produces no heat points somewhere else, often the heat exchanger or the ignition sequence. Both situations get traced to the source before any repair is quoted.
The air handler and blower move conditioned air through the duct system. A blower motor that is drawing too much current, running slower than it should, or failing intermittently shows up as reduced airflow throughout the home. Evaporator coil cleaning is part of air handler service when buildup has restricted heat transfer and is forcing the system to work harder to reach the set temperature.
A boiler heats the living space through a hydronic loop, which puts it firmly on the heating side of the work we do. Common faults include pressure loss in the system, a circulator pump that is not moving water through the loop, and zone valve failures that leave part of the home without heat. We diagnose and repair hydronic heating systems the same way we approach any other heating call: the fault is identified before any repair is quoted.
Not the biggest name in town. Just the one that answers. No runaround.
Johns Creek is our primary service area in Fulton County. We also cover Berkeley Lake, Duluth, Alpharetta, Peachtree Corners, and Norcross, along with the broader communities across this part of the county and into the surrounding region. If you are not sure whether we reach your address, call and ask. We will confirm it on the call.
It helps. If the air handler is in a closet, utility room, or attic with limited clearance, making sure the area is accessible before the visit saves time. We ask about access when the job is scoped on the call.
Yes. We service equipment regardless of who installed it. The make and model matter more than the installer. If you have the equipment details, share them on the call and we will confirm what the visit covers.
Yes. For situations where both options are genuinely on the table, we explain what each involves and what each costs before any decision is made. Installation work comes with a written scope, and repair options are quoted before work starts, so you have the information you need to make the call.
Yes. Removal of the existing equipment is part of a replacement job. We include it in the written scope so the plan is clear before the work starts.
Yes. If the diagnostic finds faults on both the heating and cooling sides of the system, we work through both in the same visit where the scope allows. Sometimes the two problems share a cause, such as a refrigerant issue that affects a heat pump in both modes. We confirm what the visit will cover on the call before anything is scheduled.
Check the thermostat first: confirm it is set to the right mode and temperature, and replace the batteries if they have not been changed recently. Then check that the circuit breaker serving the unit has not tripped.
If neither of those resolves the issue, call us at (770) 635-5441 and we will scope the situation from there.
Yes. The more specific the description, the more useful the scoping conversation on the call. "The system runs but the house never cools below 78 degrees" and "the system turns on and immediately shuts off" point toward different faults. A specific description helps us prepare the visit for the most likely cause.
Newer systems often have more sophisticated controls and variable-speed components that need to be tested differently from older single-stage equipment. Older homes may have ductwork that was installed before current load-calculation standards, which can affect airflow and system performance in ways that show up during a tune-up inspection. The visit covers what the specific system in front of us needs rather than a fixed script. What matters is what the equipment is actually doing, not how old the house is.
Tell us what the system is doing, or not doing, and we will work through the rest from there. We take calls every day from 7:30 AM to 10:00 PM.

Whether the call is about a furnace that stopped firing on a cold January night or a central AC that quit in the middle of a Georgia summer, we handle the full range of heating and cooling work across Johns Creek and Fulton County. The table below covers every service we offer, who it fits best, and what is good to know before you call. Read through, find what matches your situation, and give us a call to get the details on your specific system.
| System Service | What's Included | Best Suited For | What to Keep in Mind |
|---|---|---|---|
| Ductwork Repair & Sealing |
| Homes where one room is always too warm or too cool, or where the system runs constantly without reaching the set temperature | Conditioned air escaping into an attic or crawl space before it reaches the living area is one of the most common reasons a system runs long and still underperforms |
| Whole-Home Dehumidification & Humidity Control |
| Georgia homeowners whose AC runs constantly but the house still feels muggy through summer | High indoor humidity makes a 75-degree room feel warmer than it is and creates conditions where mold can develop in ductwork and wall cavities |
| Full System Installation & Replacement |
| Homeowners replacing aging equipment or upgrading an undersized or mismatched system | Oversized equipment short-cycles and leaves the house feeling clammy. Getting the sizing right determines how the system performs for years to come |
Call us at (770) 635-5441 between 7:30 AM and 10:00 PM, any day of the week, and we will walk through your system, your situation, and what the work involves before anything is scheduled.
