When your AC quits in Tampa, every hour matters. This isn't a mild-climate inconvenience — it's 90 degrees with humidity that soaks through everything, and a house that turns into an oven by mid-afternoon. Mendoza Heating and Air exists for exactly that moment: a local crew that answers the phone, shows up fast, and fixes what's actually wrong.
We're not a call center and we're not a franchise reading from a script. We're Tampa techs who've seen every failure this climate can throw at a system — capacitors cooked by August heat, drain lines clogged with algae, coils frozen solid from low airflow. Most of the repairs we do take under two hours once we're on site, because we carry the common parts on the truck and we diagnose before we quote, not the other way around.
From failed capacitors and fan motors to refrigerant leaks and frozen coils, we service most major brands. If a repair doesn't make sense for the age of your system, we'll tell you that too — and show you the math.
Here's the honest version, not the marketing version. When you call (813) 770-2722, a real person answers — during business hours that's us directly, and after hours our emergency line rolls to an on-call tech. We give you the earliest real window we have, not a four-hour block where you sit around wondering.
Same-day service is available across Tampa and the surrounding areas. If you call in the morning, we work to get you on the schedule that same day. If it's late in the day and the schedule is genuinely full, we'll tell you that straight and put you first the next morning — we'd rather be honest about tomorrow than promise today and show up late.
For true emergencies — no cooling at all with elderly residents, infants, or medical needs in the house, or water actively leaking from the air handler — we run 24/7. Nights, weekends, holidays. That's the call we drop everything for.
Once we're there, most repairs finish in a single visit. We stock capacitors, contactors, fan motors, thermostats, drain-line supplies, and the other high-failure parts on every truck, so the most common fixes don't need a return trip or a parts order. If something does need ordering — a control board, a blower motor for an older unit — we'll tell you the timeline upfront and get the order in the same day.
“Nine times out of ten it’s a small part that quit — capacitor, contactor, a clogged drain. The big bills come from waiting. If it’s acting up, call before it quits on a Saturday night.”
These are the calls we run every single week in Tampa. Here's what's usually going on — and what it actually takes to fix.
Nine times out of ten, this is airflow or a small electrical part — a weak capacitor that can't start the compressor, a clogged filter choking the system, or a frozen evaporator coil. The expensive version of this call is the one where someone kept running it for a week hoping it would "get better" and burned out the compressor instead. If it's blowing warm, turn it off and call — running a struggling system is what turns a $200 fix into a $2,000 one.
Ice on the copper lines or the indoor coil means the system can't breathe — low refrigerant, a filthy filter, or a blower that's not moving enough air. First step is always the same: turn the system OFF and let it thaw completely, which takes a few hours. Running it frozen just makes it worse. Then we find the actual cause instead of just thawing it and hoping.
In Tampa's humidity, your AC pulls gallons of water out of the air every day, and all of it drains through a single PVC line. Algae grows in that line, it clogs, and water backs up — onto ceilings, into closets, across floors. It's the most preventable repair we do. A $75 tune-up includes clearing and treating that drain line, which is a lot cheaper than drywall repair.
Squealing is usually a blower motor bearing on its way out. Grinding is metal on metal — shut it off. Banging at startup can be a compressor struggling against pressure. Noises are the system telling you something's wrong before it fails completely, which makes them the cheapest calls we get — if you don't ignore them for a month.
Short-cycling murders efficiency and wears out parts fast. Common causes: an oversized system, a thermostat in a bad spot (near a vent or in direct sun), or low refrigerant tripping safety switches. This one needs a real diagnosis — guessing at it wastes money, because the fix for a bad thermostat location is very different from the fix for a refrigerant issue.
Before you assume the AC is dying, check the thermostat — dead batteries, a unit knocked out of calibration, or a thermostat mounted where it reads the wrong temperature cause a surprising number of our calls. If the thermostat checks out and rooms still won't cool evenly, that's usually ductwork: crushed runs, disconnected joints, or ducts that were never sized right for the house.
And the honest pricing part: we quote before we work, in plain numbers. If a repair doesn't make sense — say, a 15-year-old system needing a $1,500 compressor — we'll show you the math on replacement instead of selling you a repair you'll regret. Sometimes the right answer is a new system, and we'll tell you when it is.
Same-day service is available across Tampa and the surrounding areas. Call in the morning and we work to get you on the schedule that day. True emergencies — no cooling with vulnerable people in the home, or active water leaks — run 24/7, nights and weekends included. Call (813) 770-2722 and we'll give you today's earliest honest window.
We diagnose the system fully before quoting any work, and you'll know the cost before we touch a wrench. Call (813) 770-2722 and ask — we'll give you the straight answer for your situation.
Depends on the repair and the system. A $200 capacitor on a 12-year-old unit that runs fine otherwise? Repair it. A $1,500 compressor on a 15-year-old system? That's replacement math, and we'll show it to you honestly instead of selling the repair. If replacement's the call, ask about the $500-off deal running right now — it includes a free UV light and a 10-year parts warranty.
We service all major residential and commercial brands — Carrier, Trane, Lennox, Goodman, Rheem, York, Amana, and the rest. The parts that fail are largely the same across brands, and we stock them on the truck.
Almost always airflow or refrigerant — dirty filter, blower issue, or a slow leak. Turn the system off and let it thaw fully (a few hours), then call. Running it frozen risks the compressor, which is the most expensive part in the system.
Turn the system off to stop more water, then call us — it's usually a clogged condensate drain, a fast fix. But don't let it sit: standing water ruins ceilings, floors, and grows mold fast in Tampa humidity.
Yes — plans starting at $199 with Basic, Priority, and Elite tiers. Two tune-ups a year, priority scheduling, and discounts on repairs. Most breakdowns we see started as skipped maintenance, so the plan usually pays for itself the first time something doesn't break.
