Another Saturday morning and the air conditioner will not restart. The outdoor fan sits still. Last August it was the capacitor. In March it was a refrigerant leak. You live in St. Petersburg, where cooling is not optional for most of the year. You are done with temporary fixes. You want a complete AC installation that lasts through the long cooling season and the wet months that follow.

At Kron & West Air Conditioning we treat that decision as a technical project, not a product swap. We have completed HVAC installation work across the Tampa Bay area since 1984. We service all makes and models. If you leave your current provider, we can honor manufacturer part warranties and most extended warranty plans. Our NATE certified technicians size the system, protect your floors and furnishings, pull permits, and stay with the job through startup and the first season.

When Repeated Repairs Stop Making Sense

An air conditioner does not usually fail in one afternoon. Capacity fades. Runtime stretches. Humidity inside the house climbs even when the thermostat is satisfied. You pay for a repair, then another. In a climate like St. Petersburg, a system that is 12 to 15 years old often costs more to keep alive than to replace. Compressors work harder. Coils corrode. Motors draw more current. The refrigerant that the unit was built around may no longer be practical to recharge.

We look at the whole picture before we recommend AC installation. We check remaining life of the air handler or furnace, the condition of the duct system, and the electrical service at the disconnect. We ask how many times you called for air conditioning service or AC repair in the last two seasons. Frequent callbacks are a signal. So is a system that cools the main rooms and leaves the west-facing bedrooms warm. Replacement is the right path when repairs only restore a fraction of the original capacity and the next failure is likely during the next heat wave.

If you still have coverage on parts, bring that paperwork. Kron & West Air Conditioning can often continue those manufacturer warranties after we take over the equipment. That matters when you are mid-plan on an extended warranty and you do not want to start over. We put every new warranty in writing. Those warranties transfer if you sell the property. We include a comprehensive first-year maintenance program with a new installation so the first cooling season is covered under a planned schedule, not a panic call.

Sizing the System for Heat, Humidity, and Your Floor Plan

A nameplate tonnage taken from the old condenser is not a design. Homes in St. Petersburg vary. A 1950s bungalow with single-pane windows does not share a load with a newer two-story house that has impact glass and a sealed attic. Orientation matters. A west wall of glass adds late-day heat that a north-facing plan does not. Occupancy, kitchen equipment, and the number of bathrooms all change the latent load. Humidity is the hidden half of the job here. If we ignore latent load, the new unit will short-cycle. The air will feel cool and clammy. Mold risk rises in closets and on supply registers.

We run a room-by-room load calculation before we order equipment. We measure glass area, insulation levels, and infiltration. We look at duct location. Ducts in a vented attic pick up heat that the equipment must then remove. We do not guess square footage from the tax record and call that enough. Oversizing is common in this market and it is a mistake. An oversized system reaches setpoint too fast, shuts off, and leaves moisture in the air. Undersizing is just as bad. The unit runs without rest and still cannot hold 75 degrees on a 95-degree afternoon. The correct size is the one that removes heat and moisture at the rate your house produces them on a design day.

Equipment selection follows the calculation. We match the outdoor unit to the indoor coil or air handler so the pair is a listed combination. Matched systems deliver the efficiency and capacity the manufacturer published. Mismatched coils do not. We talk through single-stage, two-stage, and variable-speed options in plain terms. Variable-speed equipment runs longer at lower capacity. That longer run time pulls more moisture out of the air, which is useful in St. Petersburg from May through October. We also look at the existing electrical circuit. A new higher-efficiency condenser may need a different breaker and a new disconnect. We verify that before installation day so we do not stop the job halfway through.

Clearing the Old System and Protecting the House

Installation starts with removal. We recover remaining refrigerant with certified recovery equipment. We do not vent it. We disconnect power at the breaker and at the disconnect. We cap or remove the old line set when the tubing is the wrong diameter, contaminated, or too damaged to reuse. Reusing a dirty line set is a common cause of early compressor failure on a new system. If the copper is sound and the size is correct, we flush and pressure-test it. If it is not, we run new lines.

We take steps to protect your home and furnishings. Drop cloths go down on traffic paths. We watch corners, door frames, and stair rails when we move an air handler out of a closet or attic. Outdoor units come off the pad with care so we do not crack driveways or tear irrigation lines. Condensate pans and old PVC drains come out so we can start the new drain path clean. Algae and sludge in an old drain will clog a new installation if we leave them in place.

Site conditions in this city need extra attention. Salt air reaches many neighborhoods. We set the new condenser where it can breathe and where spray from irrigation will not hit the coil all day. We keep required clearances on all sides so the fan can discharge heat. In low-lying areas we raise the pad when flood risk or local code requires it. A unit that sits in standing water after a storm is a unit that will fail early. We pour or set a level pad. We do not perch a new condenser on broken masonry and call it done.

Setting Equipment, Lines, and Electrical

The outdoor unit goes on the pad, level, with isolation pads if vibration would transfer into a slab or a nearby bedroom. We route the line set on the shortest practical path that still allows service access. Brazed joints are made with nitrogen flowing through the pipe so scale does not form inside the copper. Scale inside a new system travels to the metering device and the compressor. We insulate the suction line fully and protect the insulation from sun where it is exposed. UV breaks down foam in a single season if we leave it bare.

Indoors, the air handler or coil sits level so condensate flows to the drain, not into the cabinet. We install a secondary drain pan where the unit is above living space. A float switch on that pan shuts the system down before water reaches the ceiling. Primary drains get a trap and a cleanout. We pitch the PVC so water moves. We do not run a drain uphill and hope the pump will save it. If a condensate pump is required, we wire it so a failure of the pump stops the equipment before an overflow.

Electrical work follows the nameplate. The whip, the disconnect, and the breaker must match the minimum circuit ampacity and the maximum overcurrent protection on the unit. A disconnect must be within sight of the condenser. We land control wiring so the thermostat, the outdoor board, and any accessories speak the same language. If you keep an existing thermostat, we confirm it can drive the new equipment. A single-stage thermostat on a variable-speed system wastes the features you paid for. We set that up correctly on day one.

  • Line set and braze quality: Correct diameter, nitrogen purge during brazing, and a pressure test before we pull vacuum.
  • Condensate path: Primary drain with trap, secondary pan and float switch above finished space, and a clear pitch to daylight or an approved receptor.
  • Electrical match: Whip, disconnect, and breaker sized to the new nameplate, with the disconnect in sight of the outdoor unit.

Vacuum, Charge, and Airflow Before We Call It Done

After the mechanical work, we pull a deep vacuum on the refrigerant circuit. We use a micron gauge, not a compound gauge guess. We hold the vacuum to confirm there are no leaks and no moisture left in the lines. Moisture in a new system forms acids and ruins the compressor from the inside. We then weigh in the charge to the manufacturer specification, adjusted for line-set length. On a critical-charge system, a few ounces wrong will cut capacity and efficiency. We check superheat or subcooling against the chart for that model and the outdoor conditions that day.

Airflow is the other half of startup. We measure static pressure in the supply and return. High static means the blower is fighting the ducts. That noise, that hot upstairs room, and that frozen coil often start there. We check filter size and rack condition. A restrictive filter on a new high-efficiency air handler will starve the coil. We verify that supply registers are open and that return paths exist for every closed bedroom. A house that was never balanced will not suddenly balance because the equipment is new. We make the adjustments we can on installation day and we tell you plainly if the duct system needs more work later.

The thermostat program comes last. We set fan mode, cooling stages, and any dehumidification features the equipment supports. We walk you through the basic functions so you are not guessing at midnight. We do not leave until the system has run long enough to show stable temperatures and a dry drain. Our installation manager reviews the completed work. The entire installation must meet or exceed the manufacturer recommendations. We use new, top-quality parts and materials only. Test equipment stays calibrated. You receive written warranties, not a verbal promise at the door.

  1. Vacuum and hold: Micron gauge to a deep vacuum and a decay test so moisture and leaks are not left in the circuit.
  2. Weighed charge: Factory charge adjusted for line length, then confirmed with superheat or subcooling on that model.
  3. Airflow check: Static pressure, filter, and register verification so the coil receives the CFM it was designed for.
  4. Documented closeout: Written warranties, model and serial numbers on file, and a first-year maintenance schedule in place.

Permits, First-Year Coverage, and What We Stand Behind

AC installation in St. Petersburg requires permits and inspection. We handle the permit package. We meet the inspector. You should not have to learn the mechanical code to get a legal installation. A permitted job protects you at resale and keeps the manufacturer warranty intact. Unpermitted change-outs create problems years later when a buyer’s inspector flags the work. We build that step into the schedule so it is not an afterthought the week after we leave.

Kron & West Air Conditioning includes a comprehensive first-year maintenance program with a new installation. That first cooling season is when small issues show themselves: a drain that needs a flush, a filter that loads faster than expected, a thermostat setting that fights the humidity. We come back on a planned visit. You also have our 100% WOW Guarantee and a new-product warranty of one year and higher, depending on the equipment. Service repairs we perform carry a one-year coverage period. Warranties are in writing and they transfer. We carry liability insurance to protect you and your home. Workman’s compensation is in place if one of our people is injured on your property.

We follow up after the job to confirm you are comfortable. If something is wrong, we respond quickly. That is the standard Marina Kron set for the service department and it applies to installation as well. Our goal is your comfort. We work throughout St. Petersburg and St. Petersburg, South Pasadena, St. Pete Beach, Gulfport, Treasure Island, Madeira Beach, Redington Beach, Tierra Verde & Pinellas Park, FL. For immediate help, call the office at (727) 345-0317. That line is available 24 hours a day. If you email, put a clear subject line so we can route the request to the right person the first time.

A new air conditioner is a long-term part of the house. The pad, the lines, the charge, and the airflow either support that life or shorten it. We install for the climate you actually live in: long cooling hours, high moisture, salt in the air near the water, and attics that run hot. We do not treat St. Petersburg like a generic market. We size for this heat. We drain for this humidity. We set equipment where storms and spray will not destroy it in three seasons. That is the work. That is what you should expect when you schedule AC installation with Kron & West Air Conditioning.

  • Written, transferable warranties: Coverage you can read and pass to a future owner, not a handshake at the truck.
  • First-year maintenance included: Planned service during the first cooling season so small issues are caught early.
  • Insured crew and protected home: Liability coverage, workman’s compensation, and job-site protection for floors and furnishings.
