What we see in St. Pete homes
1920s to 1950s bungalows in Old Northeast
Tight closets and low attics leave little room for a modern air handler or a full duct redesign. Cast iron drain stacks and galvanized supply still show up in walls, and original or early panels struggle when a heat pump or EV charger is added.
Bayfront homes in Snell Isle
Salt air hits outdoor coils year round on these Tampa Bay streets. Condensers and disconnects need corrosion-aware hardware and cleaner maintenance intervals than inland blocks a few miles west.
Mid-century block ranches in Pinellas Point
Block ranches from the city median era around 1969 often still run aging flex duct and full panels. Heat pump swaps, water heater change-outs and standby circuits are the usual triggers for a capacity check.
Mid-century homes in Disston Heights
Second systems and larger electrical loads pile onto services that were sized for strip heat and a single AC. We walk the panel and the attic before quoting a compressor, charger or generator transfer switch.

St. Petersburg questions
Find quick answers to the most common questions about our services.
Do you serve all of St. Petersburg?
Yes. Downtown, Old Northeast, Historic Kenwood, Crescent Lake, Snell Isle, Shore Acres, Venetian Isles, Pinellas Point, Lakewood Estates, Tyrone, Disston Heights, Childs Park and North St. Pete/Gateway are all in range. We also cover neighboring Kenneth City and South Pasadena when the call shares a St. Pete ZIP.
Do I need a permit to replace my AC in St. Pete?
Yes for a normal central system change-out. The City of St. Petersburg Construction Services and Permitting office issues the mechanical permit. Licensed contractors registered with the City can submit many residential change-outs online through Click2Gov. We pull the permit and schedule the inspection. Small portable plug-in units on the City's exempt list are a narrow exception.
My home is in a flood zone. Does that change my AC install?
It can. Parts of Snell Isle, Shore Acres, Venetian Isles and other bay-edge streets sit in FEMA AE or VE zones, and the City also maps rainfall-driven stormwater floodplains. Outdoor equipment may need to sit above a set elevation. The City's own guidance after storms is to elevate HVAC systems and outlets where flood risk applies. We check your address against the maps before we quote.
Which ZIPs do you cover in St. Petersburg?
Standard ZIPs 33701 through 33716. That fold includes core city neighborhoods plus aliases that also serve nearby beach and bay communities such as St. Pete Beach, Gulfport, Madeira Beach and Tierra Verde.
My older bungalow has little or no ductwork. What are my options?
Ductless mini-splits fit Old Northeast and Kenwood bungalows where closets and attics never left room for a full duct run. We size each head to the room and keep the outdoor unit clear of salt spray where we can.
Does salt air hurt my AC on the water?
Yes. Outdoor coils on Snell Isle, Shore Acres, Venetian Isles and other bay streets corrode faster in salt air. Coil coatings and regular maintenance slow that wear. We say so before you buy a new condenser, not after.
Do you repair cast iron drains in St. Pete?
Yes. Pre-1960 homes around Old Northeast, Kenwood and Old Southeast still run cast iron stacks and galvanized supply. We repair sections when that is sound, and we repipe when scale and leaks make patchwork a poor bet.
Do you replace older electrical panels?
Yes. We replace older and recalled panels and upsize when a heat pump, EV charger or standby generator needs more amps. City electrical permits are part of that job.
Can I get a utility rebate in St. Pete?
Ask us which utility rebates apply to your home. St. Petersburg electric service is typically Duke Energy Florida, and programs change. We match the path to your bill and equipment.
Are you open 24/7 in St. Petersburg?
Yes. St. Petersburg HVAC, plumbing and electrical calls are answered day and night. Call 1-855-682-0402. After-hours diagnostic is $149. Same-day service covers St. Petersburg.
How do you reach St. Petersburg?
Same-day service and 24/7 HVAC, plumbing and electrical calls cover St. Petersburg. We work the I-275 spine through the city, plus Central Avenue and 4th Street corridors from downtown toward the bay.
What warranty do you provide?
Our work includes a 1-year workmanship warranty. Equipment carries the manufacturer's warranty, and extended warranty options are available.
Does Comfort Club cover a standby generator?
Yes. Comfort Club members get 20% off generator repairs. Generator installations are quoted separately.

What Our Customers Say
Real Google reviews from our customers, shown word for word.
John is fantastic. He has handled the HVAC at my place for over a year now - helps with maintenance and repairs. He is very kind, timely and fast! Always reasonable with solutions. I feel at peace knowing he can help if I have any issue.
★★★★★
This is why we love dealing with Smart for all our AC needs. First, it's because of our wonderful technician Johnny, who is the most reliable, honest, nicest technician we have ever had!! He is always on time and very clean and courteous, and smart! Every time I call, you are always able to fit us in, at our convenience, and you have the best service plan in the industry! Thank you so much!! Pat and Steven
★★★★★
We had our entire HVAC system replaced last year. From the handler, to the ductwork and insulation. They were great. They came out fast and got the work done in 2 days! We just had our unit go out and John was out same day. He was extremely helpful and honest. We weren't sure why the system went down but he also provided tips to help make sure we are using the system optimally which can help prevent odd system failures. I can't recommend them enough!
★★★★★
Our a/c went out in the middle of summer so we were trying to find someone who could come out as soon as possible. They responded quickly and could've had someone out the same night, had it not started storming, but they were still able to get someone out the following morning. Ayman was great and solved the problem quickly. He let us know of things to look out for in the future with our 10yr old unit but didn't try to oversell us or pressure us into unnecessary work. We would definitely use them again!
★★★★★
SMART HEATING & COOLING is a top choice for your air conditioning needs. I contacted them on Tuesday about my unit not cooling. On Wednesday, Ayman, the service representative, arrived on time, diagnosed the issue in detail, and offered an option to repair or replace the unit. I decided to replace it. On Thursday, two technicians arrived promptly and installed the new unit in 5 1/2 hours, without taking a break. In my experience, no other company has performed as well as SMART HEATING & COOLING. I highly recommend them to anyone needing such services. THEY ARE 5 STARS ++++
★★★★★
Updated 8/2026: The first time they came out was for our upstairs a/c unit and this time we called them because our downstairs unit had stopped working. They answered on a Friday night and we were able to get something scheduled right away. Our tech this time was Spencer and he was also great and got us back up and running quickly. We've been very happy with the service both times and ended up signing up for the maintenance plan. Both times the techs have provided thorough explanations and taken pictures to show the work that needed to be done.
★★★★★
This is my second involvement with Smart Heating & Cooling, as prior, wonderfully smooth. The tech is really good, clean, neat and considerate. The gentleman sent was a Tech by the name Jared(please pardon if mispelled) was early which I love, very presentable and totally approachable and trustworthy. He identified the problem within minutes and was very professional in his delivery. One of the best customer experiences I have had with contractors, Smart Heating & Cooling, definately a SMART choice, HIGHLY RECOMMEND!
