Why AC Systems in St. Petersburg, FL Need Special Attention

With the Tampa Bay and Boca Ciega Bay so close, homes in Historic Old Northeast, Pasadena, and Crescent Lake often deal with AC challenges unique to the area:

  • Salt Air Exposure – Living near Central Avenue and 4th Street North means your AC unit is more susceptible to rust and corrosion. Regular inspections and protective coatings can help extend its lifespan.
  • Intense Humidity & Moisture Buildup – Homes in Shore Acres and Venetian Isles are prone to excess indoor humidity, which can cause mold and mildew. AC maintenance, dehumidifiers, and clean ductwork can improve air quality.
  • Storm Damage & Power Surges – Sudden power outages and surges from summer storms in Disston Heights and Euclid-St. Paul can damage AC components. Installing a surge protector can prevent costly repairs.
  • Energy Drain from Large Homes & Open Floor Plans – Properties in Maximo Moorings and Bayway Isles often require high-efficiency AC systems to keep energy bills from soaring.

Most Common HVAC Services in St. Petersburg, FL

AC units in Historic Kenwood, Riviera Bay, and Shore Acres work hard throughout the year. These are some of the most frequent issues we repair:

  • Insufficient Cooling – If your AC isn’t keeping up, clogged air filters, refrigerant leaks, or blocked ducts might be the cause. This is especially common in Causeway Isles and Lake Pasadena.
  • Frequent On & Off Cycling – If your AC runs in short bursts, it could be due to dirty coils, a faulty thermostat, or improper unit size, often seen in Broadwater and Bay Pines.
  • Strange Noises – Grinding, rattling, or buzzing sounds can mean loose components, fan issues, or compressor failure, which we often see in Isla Del Sol and Dolphin Cay.
  • Leaking Water – A clogged condensate drain or frozen coils can cause leaks, leading to mold growth and water damage—common in St. Pete Beach and Treasure Island.
  • Skyrocketing Energy Bills – A failing or outdated AC system may be overworking to cool your home, increasing your utility costs. Many homeowners in Lakewood Estates and Pink Streets opt for energy-efficient AC upgrades to lower expenses.

No heat, first off found AC running when thermostat was set to heat mode. This is a straight cool system with electric heat not a heat pump. Found thermostat set up for heat pump with auxiliary heat. Set and reprogrammed thermostat for conventional heat with electric heat. Heat still not working, found burnt out high limit on electric heat element and wires disconnected. This most likely happened from the evaporator coil being completely plugged with no room to breathe, causing high limit to overheat. There is a heavy amount of biological growth inside of air handler. Gave client solutions for issues with system. Recommended pulling and cleaning evaporator coil as well as blower wheel, sanitizing and disinfecting the air handler cabinet, installing UV lights to prevent biological growth from forming in the future, and replacing 5KW electronic heating element. also offered client prime membership. Client wants to think about it and review options and will get back to us.

Client says system was freezing up, client let system thaw overnight. Indoor blower is intermittently not kicking on which most likely caused the coil to freeze, also evaporator coil has heavy amounts of biological growth buildup, there is no surge protection on indoor or outdoor unit, compressor has high startup amps, and condenser fan motor has high running amps. Gave client solutions for issues with system, however, system is 11 years old and recommended replacing due to age and cost of repairs. Client decided to just do minimum repairs for now and wants to keep the system going for the next 2 to 3 years. Scheduled to replace blower motor with X 13 universal motor and install hard start kit to reduce compressor start up amps. Scheduled for tomorrow, December 31 between 12 and 4.

Alexander did an excellent job tonight! Our air conditioning stopped working in the late afternoon and we noticed slightly after 5:00 PM. We called Mason air conditioning and they promised to send someone out this evening. Alexander arrived earlier than expected. He diagnosed the situation. He solved the main problem. He identified another potential problem. And because of his good work, our air conditioning was back up and running. He also identified additional work that can be done to prevent future issues and promise to come take care of that. We could not be more pleased.

He claimed to have over 20 years experience and AC work but gave me a wrong diagnostic on my AC unit saying that it had a leak and I needed Freon and a leak detection oil which would have cost me over $700 !!! When in fact, it was never that !! he never checked the Duck work in the garage, which had came loose and needed to be replaced so that I wouldn’t be sucking in hot air from the garage once that was fixed. My house is ice cold. I always believe that if you are in business and can’t figure something out at least be honest.

I meant a delightful technician who works for Mason's air conditioning company here in Pinellas County, his name is Cruz, he had been out to my house prior for another issue, I have an older AC model but unfortunately I don't have the cash to buy a brand new one so therefore I guess I'm kind of like putting new shoes on a new vehicle one tire at a time, unfortunately you put one new equipment on the old AC then sometimes it doesn't recognize that you put a brand new part on so therefore another issue pops up. That was the case with me I have an older AC unit and unfortunately do the fact that I am lightly seasoned and live on social security to produce the money to buy a whole new unit was not even in my equation the finances. However, would that being said I needed a new blower up in my attic my problem is I care for a rescue cats I always ask any type of companies that have to come service the inside of my house are you allergic to cats? I was provided with one and he was severely allergic I said no I don't I was so awful and the other one would not be available for the next day that was not a problem that person was not allergic to cats and I was delighted, the technician that came to my front door was again Cruz, one of my cat said oh boy new person to come in and she like right there basically in his lap so that was a good thing. Cruise was there on a Saturday April 27th to replace the blower that had taken a permanent sabbatical it need to be replaced. Once again I have to ask who's coming and are they allergic to cats at the later end of the day I did receive notation that Cruz was going to come out on Saturday to install the new blower what I didn't realize was it was his day off I said no no I said I don't want him to take his day off as long as you find me somebody that's not allergic to cats that would be fine, Cruz wasn't having it he knows my system he is not allergic to cats the cats like him and he didn't have a problem coming in on his day off now that's dedication and I can certainly appreciate that. Unfortunately I had to have another tire put to my car which means I had to have a new blower installed in the Attic. He did an awesome job installing it and cleaned up after himself and once again I thanked him at the bottom of my heart for coming in on his day off he says no problem no problem at all I was honored to do it. The house is starting to cool off which I was excited I've not had the AC working and a month. You know it's hard to trust somebody else when you've been working with one particular technician doesn't mean that they're all not good and and otherwise they would not be working at Mason's Air Conditioning company but just like going to the doctors it's hard to have to change over to a new one because you so used to one person doing a certain way. I wanted Cruz to know thank you I appreciate all your hard work and all your knowledge and your TLC and making me feel like I'm part of the family and even a little bit of yours you're the best Thank you Mason air conditioning company for hiring him that was an excellent choice he's a great asset to the company he's a great asset to the customers and he's a great asset to the community thank you for all that you do.
