Frequently Asked Questions - HVAC in Miami, FL
Straight answers to the questions Miami homeowners ask us most about heating and air conditioning, pricing, and how we work at Dalton Heating & Air.
Pricing & Cost FAQs
Most AC repairs in Miami run between $150 and $650, with the final number depending on the part that failed and how accessible the unit is. A capacitor replacement sits at the low end. A compressor or evaporator coil job runs higher. We give every customer a written price before any work starts, so the number doesn't move at the door. Flat rate, not hourly guessing. If you're seeing weak airflow, warm air, or a unit that short cycles, call (850) 754-6042 and we'll send someone out to diagnose it properly.
A full system replacement in Miami, including the condenser, air handler, and installation, typically spans $6,500 to $14,000 depending on home size, SEER rating, and ductwork condition. Homes in neighborhoods like Kendall or Coral Gables with older duct runs often need additional work that shifts the final price. We never quote a system over the phone without seeing the house. What we do is a written fixed price after a proper load calculation. You'll know the exact number before you sign anything.
Demand spikes hard between June and September in Miami, and parts warehouses run thinner on common failures like capacitors and contactors. That's market reality, not an excuse to inflate prices. We keep our rate card the same year-round. What changes is scheduling pressure, so we tell customers in April and May to get a maintenance visit in before the humidity settles in. A clean, charged system survives the summer crunch far more often than one that's been ignored for two years.
No. Our estimates are free, and they come in writing with the full scope of work and a fixed price. That's part of The Garrison Standard every location works under. No hidden dispatch fee, no fee to knock on the door. If you're comparing quotes for a replacement system, you'll get ours itemized so you can see exactly where the money goes. Call (850) 754-6042 and we'll schedule a time that works inside our posted hours.
If the repair costs more than 40% of the system's value and the unit is over 12 years old, replacement usually makes more sense in Miami's climate. Our coastal humidity ages evaporator coils faster than drier markets, and older R-22 systems cost more to recharge every time they leak. Marco Benitez and our team will walk you through the math honestly, even when the honest answer is a repair. We'd rather you trust us for the next decade than squeeze one more job out of a dying unit.
Service & Process FAQs
Our technician checks refrigerant charge, cleans the condenser and evaporator coils, inspects electrical connections, tests the capacitor and contactor, measures temperature split, and clears the condensate drain line. Every finding goes in a written report you keep. We don't pay our technicians on what they sell, so the report is a condition report, not a sales pitch. In Miami's salt air, coil cleaning alone keeps efficiency from sliding every year.
We do, on every full system replacement, no exceptions. A Manual J load calculation uses your home's square footage, window orientation, insulation levels, and local Miami climate data to size the equipment correctly. Oversized units short cycle and leave humidity in the house. Undersized units run constantly and still can't hit setpoint. Getting this step right is the difference between a system that lasts 15 years and one that struggles from day one.
We work regularly with York, Bryant, and American Standard equipment, and we service all major brands regardless of what's already in the house. Parts availability in Miami is strong for those lines, which means faster repairs when something fails. If you have a Daikin system, we can source those parts too. The installer matters more than the badge on the cabinet, and our installs follow the manufacturer's spec to the letter.
We inspect ductwork during every system replacement and on any service call where airflow issues point that direction. Miami attics run brutally hot and humid, and duct leaks in that environment waste cooled air into a space you don't live in. We can seal and repair accessible duct runs, replace collapsed sections, and re-insulate plenums. Full duct replacement is priced separately and is sometimes the right call in homes in Westchester or Tamiami with original 1980s flex duct.
A standard system replacement, swapping the condenser and air handler, takes one full day for a two-person crew. Jobs that include duct modifications, new line sets, or moving the air handler to a different location can run two days. We give you the timeline in writing before we start, and we stick to it. You'll know which day we arrive, and the crew won't leave until the system is running, charged, tested, and the site is clean.
Brands & Parts FAQs
For Miami's heat and humidity, we lean toward York and Bryant systems with higher SEER2 ratings and good dehumidification performance. American Standard has strong options too, particularly for quieter operation. The real answer is that proper sizing and install quality matter more than the badge. A perfectly installed mid-tier system outperforms a premium brand slapped in by someone who skipped the details. We'll recommend what fits your home and budget, not what's left in the warehouse.
It depends on the unit's age and refrigerant type. R-22 systems, which were phased out for new manufacture in 2010, still have some aftermarket parts available but the refrigerant itself has become expensive. Common parts like capacitors, contactors, fan motors, and contactors for newer R-410A and R-454B systems are stocked locally in Miami. If your unit is 15 years old and needs a major component, we'll tell you plainly when parts chasing no longer makes financial sense.
We typically recommend 16 to 18 SEER2 for most Miami homes. That range balances upfront cost against the long electric bills our cooling season produces. Miami runs AC nearly year-round, so efficiency pays back faster here than almost anywhere in the country. Higher ratings make sense for larger homes or anyone planning to stay put for a decade. Lower ratings look cheaper on purchase day and regretful by the first August bill.
Licensing & Insurance FAQs
Yes. Every technician working under the Dalton Heating & Air name is required to hold the license and insurance their state requires. The company is insured and bonded, and we're led locally by Marco Benitez, who has built his reputation in the Miami HVAC trade on doing work by the book the first time. You're welcome to ask for documentation when our technician arrives. A legitimate operation will never hesitate to show it.
When the work requires a permit under local building code, we pull it before the job starts and close it out when the inspection passes. Full system replacements in Miami-Dade County generally require a permit, and the homeowner should always confirm that the contractor is handling it. We handle the paperwork, schedule the inspection, and make sure everything passes the first time. It's part of doing it by the book.
The Garrison Standard is the promise every Dalton Heating & Air location works under. We arrive inside the window we gave you, put the price in writing before any work starts, do the job by the book, and leave the site clean and squared away. The work is guaranteed in writing for a full year. If it fails in that time, we come back and make it right at no charge. It's not a slogan. It's how the crew runs every day in Miami.
Emergency & Response FAQs
We offer same-day service during our operating hours when our schedule allows, and we're open Monday through Friday from 7:00 AM to 7:00 PM and Sunday from 7:00 AM to 7:00 PM. Miami's heat doesn't respect a calendar, and we keep Sunday hours specifically because that's when a lot of systems decide to quit. Call (850) 754-6042 as early as you can, and the coordinator will get you on the board.
First, check the easy things: thermostat setting, a tripped breaker, a dirty filter blocking airflow, and an overflowing condensate pan that may have triggered a float switch. If none of those are the culprit, turn the system off to prevent further damage and call (850) 754-6042 during our posted hours. Running a unit with low refrigerant or a seized compressor can turn a $200 repair into a $2,000 replacement. In Miami's summer, don't wait and hope it sorts itself out.
We're open Sunday from 7:00 AM to 7:00 PM, which covers a lot of the weekend breakdowns that Saturday brings to light. We're closed Saturday so our team gets a full day of rest. Monday through Friday we run 7:00 AM to 7:00 PM. Summer weekends in Miami are when systems fail most often, and we keep Sunday staffed to handle it.
Warranty & Guarantees FAQs
Our work is guaranteed in writing for a full year. If anything we installed or repaired fails within that time due to our workmanship, we come back and make it right at no charge. Manufacturer warranties on parts and equipment run separately and typically cover the major components for 5 to 10 years, sometimes longer with registered systems. We register all equipment warranties with the manufacturer so you don't lose coverage by forgetting the paperwork.
Yes, we process manufacturer warranty claims on systems we've installed and on systems we service. If a covered part fails, we handle the claim paperwork, order the part, and install it. You typically pay for labor unless a labor warranty is in place, which we offer as an option on new systems. We'll explain exactly what's covered and what's not before the work begins, in writing, so there are no surprises.
We don't recommend it. Modern AC systems involve high-voltage electrical components, pressurized refrigerant, and precise charging requirements. Refrigerant handling is regulated by federal law and requires EPA certification, which is a legal issue, not just a safety one. Electrical components carry genuine shock and fire risk. Florida code also requires licensed contractors for much of this work. What you can do is change filters monthly and keep the outdoor unit clear of debris. Leave the rest to trained professionals.
