Frequently Asked Questions - HVAC in Alpharetta, GA
Straight answers to the HVAC questions we hear most from homeowners in Alpharetta, Milton, Roswell, and the north Fulton area. If you don't see your question here, call us at (229) 537-2086 and ask directly.
Pricing & Cost FAQs
Most HVAC repairs in Alpharetta run between $150 and $600 depending on the part and the system. A capacitor or contactor replacement typically falls at the low end, while a blower motor or circuit board lands higher. The Alpharetta climate, with hot humid summers, means compressors and condensers work hard, so failures cluster in July and August. We give you a written price range before any work starts, so the number doesn't move at the door. Call (229) 537-2086 and we'll get a technician out to diagnose what's actually wrong.
A new furnace and AC system in Alpharetta typically costs between $6,500 and $12,500 installed. The spread depends on system size, efficiency rating, and whether your ductwork needs attention. A 3-ton system for a typical 2,000-square-foot home in Milton or Roswell generally runs mid-range, while high-efficiency heat pumps with variable-speed blowers push toward the top. We price every job in writing before the work starts, with no surprises on install day. Call (229) 537-2086 for a free written estimate.
Prices vary because equipment quality, installation standards, and warranty coverage differ more than most homeowners realize. A quote that cuts cost usually cuts somewhere: cheaper equipment, skipped permits, no load calculation, or no written guarantee. In Alpharetta, where summer heat exposes every weakness, we'd rather show you exactly what you're getting. Every quote from Dalton Heating & Air Alpharetta includes the equipment brand, the efficiency rating, and The Garrison Standard guarantee in writing before you sign anything.
Yes, we provide free written estimates for system replacements and new installations anywhere in Alpharetta and the surrounding north Fulton county areas. The estimate covers the exact equipment, the full scope of work, and the price you'll pay, all in writing. If a repair is needed instead, the service call includes the diagnosis and we'll tell you the repair cost before we touch anything. Call (229) 537-2086 to schedule an estimate.
A seasonal HVAC tune-up in Alpharetta typically costs between $89 and $189 depending on the system type and the level of inspection. For most homes, an annual cooling check before summer and a heating check before winter catches small problems before they become July emergencies. Our technicians write up what they actually found, not what they want to sell you, and they aren't paid on what they recommend. Call (229) 537-2086 for this season's tune-up pricing.
Replace when the repair costs more than roughly a third of a new system and the unit is past 10 to 12 years old. In Alpharetta, where systems run hard from May through September, an aging unit with a major failure, like a compressor or heat exchanger, usually signals it's time. Repair makes sense when the system is younger, the failure is isolated, and the rest of the equipment is in good shape. We'll walk you through the math honestly, without a push in either direction. Call (229) 537-2086 and we'll help you decide based on your actual unit, not a sales script.
Service & Process FAQs
A technician arrives at your home, listens to what you've noticed, and then inspects the system from the thermostat through the air handler and the outdoor unit. You get a written diagnosis and a price before any repair work starts. If parts are needed, we tell you what they are, what they cost, and when they can be installed. After the work, the technician tests the system and reviews what they did with you. That's the process on every call, whether it's in Alpharetta, Johns Creek, or Dunwoody.
Most common repairs are finished in one to two hours once the technician is on site. That covers items like capacitors, contactors, thermostats, drain line clogs, and fan motors. Bigger jobs, like an evaporator coil replacement or a compressor change-out, can take half a day or more depending on access and system type. We'll always give you a realistic time frame before the work starts, and we show up inside the window we gave you. It's part of The Garrison Code.
A full system replacement in Alpharetta usually takes one day, sometimes a second morning for larger or more complex homes. The install crew handles the removal of the old equipment, the new furnace and condenser, the line set and the thermostat, and then runs the system through a full sequence of operation to confirm everything is correct. Before they leave, the site is clean and squared away. We set the install date in writing and hold to it. Call (229) 537-2086 for a written quote and a set schedule.
Yes, an adult should be home for tune-ups and repairs so the technician can access the system, ask about any issues you've noticed, and review findings with you afterward. It also gives you a chance to see what the technician found on the written report. For installations, you'll need to be home at the start and end of the job at minimum. We coordinate the arrival window with you when we schedule the call. Call (229) 537-2086 to set up a time that works.
We serve Alpharetta and the surrounding north Fulton and Gwinnett communities, including Milton, Duluth, Sugar Hill, Buford, Cumming, Roswell, Johns Creek, Dunwoody, Norcross, and Clarkston. If you're unsure whether we cover your street, call (229) 537-2086 and our coordinator will confirm it. We spend most of our days on the local roads between these towns, so we know the neighborhoods and the housing stock well.
Brands & Parts FAQs
We work with Lennox, Goodman, and Rheem systems most often in the Alpharetta area. Each has strengths: Lennox leads on high-efficiency variable-speed equipment, Goodman on straightforward value and reliability, and Rheem on proven mid-range performance. We also service other major brands, including York. Your existing system's brand matters less than its condition and your home's actual heating and cooling load. We'll recommend what fits your house and budget, and we price it in writing before the job starts.
It's not required, but matching the inside and outside units to the same brand often gives you better efficiency ratings and cleaner warranty coverage. That said, plenty of Alpharetta homes run mixed systems without trouble, and we won't push you to replace a working component just to match labels. What actually matters is that the coil and condenser are properly matched in capacity and refrigerant type. We'll explain exactly what your system needs and why. Call (229) 537-2086 for an honest read on your setup.
In the Alpharetta climate, a well-maintained central air system typically lasts 12 to 15 years, and a furnace 15 to 20. The humidity and long cooling season here put real strain on compressors and coils, so a system that's been ignored often fails closer to the 10-year mark. Regular tune-ups, clean filters, and clear drain lines stretch the lifespan meaningfully. If your system is past the 12-year mark and showing its age, we're happy to evaluate it and give you a straight answer on where it stands. Call (229) 537-2086.
Aftermarket parts can work, but they often lack the exact fit and factory testing of OEM parts, and they may not carry the same warranty. For critical components like blower motors, control boards, and compressors, we prefer factory parts from the original brand because they're built to the system's specifications. For simple items like capacitors and contactors, a quality universal part is generally fine. Every part we install is covered by our one-year written guarantee under The Garrison Standard. Call (229) 537-2086 with any parts questions.
Licensing & Insurance FAQs
Yes. Every pro working under the Dalton Heating & Air name is required to hold the license and insurance their state requires. The same standard applies to our Alpharetta branch, where Marco Benitez leads the local team. You should never let anyone work on your home's heating or cooling without verifying those basics, because unlicensed work puts your equipment, your home, and your safety at risk. We're glad to point you to the right Georgia licensing records or answer any insurance questions when you call (229) 537-2086.
In most cases, yes. Replacing a furnace, air conditioner, or heat pump in Alpharetta typically requires a mechanical permit from the city or county. The permitting process confirms the work meets current code, which protects you as the homeowner. Our team handles the permit paperwork as part of the installation, included in your written price. If you're replacing like-for-like equipment and no ductwork is changing, some jurisdictions have a simpler process, but we still go by the book either way. That's The Garrison Code.
The Garrison Standard is the written promise behind every Dalton Heating & Air location. It means we show up inside the window we gave you, put the price in writing before any work starts, do the job by the book the first time, and leave the site clean and squared away. Then we stand behind the work for a full year. Marco Benitez and the team here in Alpharetta work to that standard on every call, whether it's a tune-up in Milton or a full install in Duluth.
Emergency & Response FAQs
We can often accommodate same-day repairs, especially during our regular hours, which are Monday through Friday 7:00 AM to 7:00 PM and Sunday 7:00 AM to 7:00 PM. When you call (229) 537-2086, a live coordinator will check the schedule for Alpharetta and the surrounding area and get you on the calendar as quickly as possible. A failed air conditioner in a Georgia summer is more than an inconvenience, it's a real comfort and health concern, so we prioritize no-cooling calls whenever possible.
Yes, a burning smell from your HVAC should be treated seriously. If the smell is dust burning off after sitting idle, it typically clears in a few minutes. If it smells like electrical burning, plastic, or gas, turn the system off at the thermostat and call for professional help right away. Natural gas furnaces present particular risks, and a technician needs to check the heat exchanger, wiring, and gas connections. Don't keep running it. Call (229) 537-2086 and describe exactly what you smell.
First, check the simple things: make sure the thermostat is set correctly, the filter isn't badly clogged, and the breaker hasn't tripped. Keep the system off if you noticed unusual noises, smells, or water leakage. Close curtains on the sunny side of the house to slow heat gain if the AC is down. Write down what you observed, including when the problem started, so the technician gets a clear picture when they arrive. Then call (229) 537-2086 and we'll get you scheduled, often the same day during our regular hours.
Warranty & Guarantees FAQs
A new system carries two layers of protection: the manufacturer's warranty on the equipment itself, typically 5 to 10 years on parts depending on the brand and registration, and our one-year written workmanship guarantee under The Garrison Standard. If anything related to our installation work fails within that first year, we come back and make it right at no charge. We register the equipment warranty for you and explain the coverage in plain language before the job starts. Call (229) 537-2086 for details on specific systems.
The guarantee covers the work we performed, not normal wear or issues unrelated to the repair or installation. If a part we installed fails, or something in our workmanship turns out to be wrong within one year, we return and correct it at no charge. That's the promise of The Garrison Standard, and it applies to every job, from a capacitor swap in Roswell to a full system replacement in Cumming. The guarantee is in writing, so there's no ambiguity about what's covered. Call (229) 537-2086 with any questions.
No, the opposite is true. Skipping regular maintenance is what puts your warranty at risk. Most manufacturers require basic care, like clean filters and clean coils, and may deny a claim if neglect caused the failure. Keep a simple record of your tune-ups, and we'll provide a written report after each visit. In Alpharetta, where systems work long summers, a spring and fall check is smart, and it protects the equipment warranty while catching small issues early. Call (229) 537-2086 to get on the maintenance schedule.
DIY vs. Professional FAQs
There are a few safe homeowner tasks, like changing the filter, clearing debris from around the outdoor unit, and making sure the drain line isn't obviously clogged. Beyond that, air conditioners contain high-voltage wiring, pressurized refrigerant, and moving parts that can cause real injury or expensive damage if handled incorrectly. Refrigerant handling legally requires certification. We'd never recommend opening the system or the electrical compartment yourself. If the basics don't solve it, call (229) 537-2086 and we'll take it from there.
You can look for simple things: a tripped breaker, a dead thermostat battery, or a closed gas valve. But furnaces involve natural gas, electrical current, and a heat exchanger that can crack and leak carbon monoxide. That's a combination where a mistaken repair has serious consequences. If your furnace isn't heating or is doing something unusual, the right move is a professional inspection. Our technicians test for carbon monoxide and check the heat exchanger and gas line on every furnace call. Call (229) 537-2086 and let a trained pro handle it.
Look for a few specific things: a real local presence, a license and insurance you can verify, a written price before work begins, and a written guarantee on the work. If a company won't put numbers in writing or pressures you to decide on the spot, walk away. Ask about the crew's training and whether the company stands behind its work. At Dalton Heating & Air Alpharetta, Marco Benitez and the team work to The Garrison Standard on every call, and the price is in writing before any work starts. Call (229) 537-2086 and see the difference for yourself.
