New air conditioning systems sized, installed, and guaranteed by licensed Gulf Coast technicians — built for Mobile's heat, humidity, and salt air. Free in-home estimates, honest pricing, and a 1-year workmanship guarantee on every install.
Call (251) 680-7500 Request a QuoteWhen you're replacing an air conditioner in Mobile, you're not just buying equipment — you're buying the installation. Industry studies consistently show that a poorly installed system can lose 20–30% of its rated efficiency before it ever cools a single room. That's why Professional Systems treats every AC installation as a complete engineering job: correct sizing with a Manual J load calculation, refrigerant charging verified by measurement, airflow balanced to your ductwork, and the electrical side handled by our own licensed electricians — not a subcontractor.
We've spent more than 20 years installing air conditioning across Mobile County and Baldwin County, and we build every system for the conditions this climate actually throws at it: cooling seasons that stretch from March to November, humidity that punishes undersized ductwork, and salt air that corrodes cut-rate equipment. As an authorized York dealer, we install systems engineered and assembled in America, backed by some of the strongest warranties in the industry — and backed again by our own 1-year workmanship guarantee.
Free, no-obligation estimates. Upfront pricing before any work begins.

Gulf Coast air conditioners work harder than almost anywhere in the country — long seasons, high humidity, and salt exposure age equipment faster here than the national average. If you recognize your system in more than one of these, an installation estimate is worth your time:
Not sure which side of the line you're on? We'll tell you honestly — our team repairs air conditioners every day, and we'll always quote a repair when a repair is the smarter call.
Professional Systems is an authorized York dealer for the Mobile area. We chose York deliberately — and after two decades installing equipment on the Gulf Coast, that choice comes down to what holds up here.
York residential systems are designed, engineered, and assembled in the United States, and every unit is run-tested before it ships. Fewer surprises on install day — and fewer callbacks after.
From solid entry-level SEER2 systems to variable-capacity inverter models that dehumidify beautifully in Mobile's climate, the York lineup covers every budget without forcing you into more machine than your home needs.
Registered York systems carry limited warranties that are among the strongest in residential HVAC — and because we're an authorized dealer, your paperwork, registration, and any future warranty claims run through a local team you can actually call.
The York YC6 16+ SEER2 air conditioner — one of the systems we install and service across Mobile.
We install York because we service what we sell. Every system we put in is one our own technicians will maintain for the next 15 years — that changes how you choose equipment.
Here's the thing nobody tells you about air conditioning in Mobile: bigger is not better. An oversized system cools the air quickly and shuts off before it's had time to wring the moisture out — leaving you with a cold, clammy house, mold-friendly humidity, and short-cycling that burns the compressor out years early. In a climate where summer dew points sit in the 70s, that's the most expensive mistake in HVAC.
That's why every Professional Systems installation starts with a Manual J load calculation — the industry-standard, room-by-room analysis of your home's actual cooling load. We measure and account for:
The result: a system that runs longer, gentler cycles, holds indoor humidity where it should be, and hits the efficiency numbers on its label — in your actual house, not a lab.
Most installations are completed in a single day. Here's exactly how it goes from first call to cold air:
Call (251) 680-7500 or request a quote online. A licensed technician — not a commissioned salesperson — evaluates your home, performs the load calculation, and walks you through good-better-best options with exact pricing.
You get equipment options, full installed pricing, efficiency comparisons, and financing terms in writing. No pressure, no expiring "today only" discounts, no surprises later.
We protect your floors, remove and responsibly dispose of the old equipment, set the new system, and handle every connection — refrigerant, condensate, and electrical — with our own licensed HVAC and electrical technicians.
We verify the refrigerant charge by measurement, confirm airflow at the registers, test cooling and dehumidification under load, and configure your thermostat before we call it done.
We show you the system, register your York warranty, and leave you with everything in writing — including our 1-year workmanship guarantee on the installation itself.
The same local team that installed your system maintains it. One number to call, for the life of the equipment — including emergency service when you need it.
Every home is different, but here's the honest framework. The installed price of a new air conditioning system depends on four things: the size (tonnage) your home needs, the efficiency tier you choose, the condition of your ductwork and electrical, and whether you're replacing a straightforward like-for-like system or changing configuration.
We provide free, no-obligation estimates with exact installed pricing in writing before any work begins — and flexible financing options that turn a new system into a predictable monthly payment. Ask about current financing promotions when you call; we'll also flag any active rebates or tax credits your chosen system qualifies for.
Request Your Free QuoteInstalling air conditioning in Mobile is not the same job it is in Birmingham or Atlanta. Our cooling season regularly runs eight months. Average summer humidity makes latent load — moisture removal — as important as raw cooling capacity. Salt air within reach of Mobile Bay corrodes coils and cabinets that would last years longer inland, which is why coil coatings and equipment placement matter here. And hurricane season means your condenser pad, tie-downs, and disconnect need to be done right, to code, every time.
We install across every kind of housing stock the area has: raised historic homes in Midtown and Oakleigh where duct routing takes real creativity, slab ranches in West Mobile and Tillmans Corner, newer construction out toward Semmes and Saraland, waterfront properties on Dog River and Fowl River where corrosion resistance drives equipment choice, and commercial spaces along the Airport Boulevard corridor. Whatever your home is, we've installed in one like it — probably on your street.
Professional Systems is headquartered at 216 E I-65 Service Rd N in Mobile, and we serve the entire metro: Mobile, Prichard, Chickasaw, Saraland, Satsuma, Semmes, Theodore, Tillmans Corner, and across the bay to Daphne, Spanish Fort, and Fairhope. Same-day estimates are usually available inside Mobile city limits.
The right system depends on your home's construction, your ductwork, and how you use your space. We install and service all of these — and we'll tell you plainly which one fits.
The workhorse of Mobile homes: an outdoor condenser paired with an indoor coil and air handler or furnace. If your home has ductwork in decent shape, a modern split system is usually the best cooling value per dollar. Available in single-stage, two-stage, and variable-capacity tiers — the higher tiers earn their keep here through superior humidity removal.
A heat pump is an air conditioner that runs in reverse for heating — and on the Gulf Coast, where winters are short and mild, it's often the smartest total-comfort buy. One system handles the whole year, heats far more efficiently than electric strip heat, and modern cold-weather performance easily covers Mobile's handful of freezing nights.
For garage conversions, sunrooms, additions, older raised homes where duct routing is impractical, or that one bedroom that never cools right — a ductless system delivers precise, efficient comfort with no ductwork at all. Each zone gets its own thermostat, and installation is typically done in a day.
Common on slab homes and light commercial buildings around Mobile, a package unit puts the whole system in one outdoor cabinet. When it's time to replace one, matching the configuration and curb correctly matters — we handle package unit swaps regularly for both homes and businesses.
Roughly half our installation calls start with a system some other company put in wrong. These are the failures we correct most often around Mobile, and what a proper installation does differently:
A good installation is invisible — it just works, quietly, for 15 years. That's the standard every Professional Systems crew is held to, and it's why we back the workmanship in writing.
Every AC installation includes electrical work — disconnects, breakers, sometimes panel capacity. We're licensed for both, so nothing gets subcontracted and nothing falls between two companies.
Two decades of installations in exactly this climate. We've seen what fails here and what lasts — and we only install what lasts.
Factory-backed equipment, dealer-level warranty support, and installation to York's specifications — which is what keeps those warranties valid.
Every installation is backed by a 1-year workmanship guarantee on top of the manufacturer's equipment warranty. If something isn't right, we make it right.
No trip fees for quotes, no pressure tactics, and the price we put in writing is the price you pay.

"I've had a new HVAC unit installed with Mark and he was courteous, kind, friendly and always on time and had great communication."
— Scott James, Loyal Gulf Coast Customer"I've worked with them on several projects and they are amazing to work with. Caleb has always been very responsive and keeps me informed of the status of each project."
— Jim Brock, Mobile, AL"Jerry and his team are prompt, trustworthy, and easy to communicate with. Jerry went out of his way to make sure I was taken care of very quickly! 10/10 recommend for any HVAC needs."
— Paul Kimsal, Daphne, ALInstalled cost depends on the size your home needs, the efficiency tier you choose, and the condition of your ductwork and electrical. Rather than quote a misleading range, we provide a free in-home estimate with exact installed pricing in writing before any work begins — and financing options that turn the project into a predictable monthly payment.
Most straightforward replacements in the Mobile area are completed in a single day — typically 4 to 8 hours. Installations involving ductwork corrections, electrical upgrades, or configuration changes can take an additional day. We'll give you the timeline in writing with your quote.
The only correct answer comes from a Manual J load calculation, which we perform on every installation. Mobile's humidity makes sizing especially critical here: an oversized unit short-cycles and leaves your home clammy, while an undersized one runs constantly and never catches up. Square-footage rules of thumb get it wrong in both directions.
Professional Systems is an authorized York dealer. York systems are designed, engineered, and assembled in America, run-tested at the factory, and carry some of the strongest limited warranties in residential HVAC when registered. Just as important: we service what we sell, so we choose equipment we're confident maintaining for the next 15 years on the Gulf Coast.
In our region, new split-system air conditioners must meet a federal minimum of 14.3 SEER2. For most Mobile homes we recommend stepping up at least one tier — the long cooling season here means efficiency upgrades pay back faster than they do up north. For the best humidity control, variable-capacity systems are worth a serious look; we'll show you the operating-cost math for each option in your estimate.
Not always — but it must be evaluated. Leaky or undersized ducts can throw away 20–30% of a new system's output, which means you paid for efficiency you never receive. We inspect ductwork during every estimate and quote corrections separately, so you can see exactly what's essential and what's optional.
Yes — and in-house, which is rare. Professional Systems is licensed for both HVAC and electrical work, so the disconnect, breaker, wiring, and any panel capacity questions are handled by our own licensed electricians on the same job. No subcontractors, no second scheduling window, no finger-pointing between trades.
Yes. We offer flexible financing options for new system installations, and we'll walk you through terms during your free estimate. Many Mobile homeowners find the monthly payment on an efficient new system is largely offset by what it saves on summer power bills.
Two layers. Your York equipment carries the manufacturer's limited warranty — among the strongest in the industry when the system is registered, which we handle for you. On top of that, Professional Systems backs the installation itself with a 1-year workmanship guarantee: if something in our work isn't right, we make it right.
Spring and fall are ideal — scheduling is flexible and you're not sweating through a heat wave while you decide. That said, we install year-round, and if your system fails in July we can typically move fast. Replacing a struggling system on your schedule always beats replacing a dead one during the first 95-degree week of summer.
