Frequently Asked Questions - HVAC in Marietta, GA
Straight answers to the HVAC questions Marietta homeowners ask us most. If you don't see yours here, call (229) 514-0545 and we'll talk it through.
Pricing & Cost FAQs
Most HVAC repairs in Marietta run between $180 and $650 depending on the part and the system. A capacitor replacement typically falls on the lower end, while a blower motor or control board lands higher. The honest answer is that no one can quote a repair accurately without seeing the unit. That's why we put the price in writing before any work starts. You see the number, you approve it, then we turn a wrench. Call (229) 514-0545 and we'll give you a straight answer, not a surprise.
A full AC replacement in Marietta typically runs between $6,000 and $14,000 depending on home size, efficiency rating, and ductwork condition. A 14 SEER basic system costs less than an 18 SEER variable-speed unit. We carry Trane, Lennox, and Goodman equipment, so the brand also affects the number. What matters most is getting a load calculation done properly. That's the only way to size a system correctly for a Marietta home. We'll give you a written fixed price, not an estimate that drifts upward.
Three things drive the gap: equipment quality, installation quality, and overhead. Cheap quotes often mean builder-grade equipment, rushed installs, or techs paid on commission who push add-ons. Higher quotes should mean better materials and better labor. The key is knowing what you're actually getting. We show you the equipment model numbers, the scope of work, and a written price before anything starts. If a competitor won't do that, the quote comparison is meaningless. Ask every company the same three questions and compare real answers.
Yes, rebates change regularly through Georgia Power, gas utilities, and manufacturer programs on qualifying high-efficiency equipment. We handle the paperwork and apply eligible rebates directly to your quote so you're not chasing forms after the install. Financing options are also available on replacement systems. The exact rebate amount depends on the SEER2 rating, the equipment brand, and your utility provider. Call (229) 514-0545 with your model details or after a quote, and we'll tell you what applies to your home.
No. Estimates are free, and they're written. You get a fixed price before you decide anything. We don't do the lowball verbal quote that doubles once the work starts. The number we put in writing is the number you pay. That includes equipment, labor, permits, and disposal. If something changes during the job, we stop and get your approval before spending another dollar. No surprises, no "while we're here" upsells.
Service & Process FAQs
You book online or by phone, pick a time that works, and we confirm with a live coordinator. On the day of service, you get a live arrival time you can track to your door instead of a four-hour window. Your tech arrives, diagnoses the issue, and sends photos of the work before and after. You approve a written price before any repair starts. When the job is done, you get a digital invoice texted to your phone that you can pay from the link. That's the whole process, and it's the Relay Standard we work to.
Most repair visits in Marietta take between 60 and 90 minutes from arrival to completion. A capacitor swap might take 30 minutes. A refrigerant leak hunt or blower motor replacement runs longer. The diagnosis itself usually takes 15 to 30 minutes, and we show you photos of what we found so you're not taking our word on faith. What slows some jobs down is parts. If your system needs a part we don't have on the truck, we'll tell you the lead time and get a second visit scheduled on the spot.
You need to be home for the initial diagnosis and any indoor work, since we need access to the unit and the thermostat. If you're stepping out mid-visit, just let the tech know. For outdoor condenser work on a follow-up visit, some Marietta homeowners leave us to it. But we do send before and after photos either way, so you'll see what was done. And you'll get a text with arrival tracking, so you'll know exactly when your tech pulls up.
Yes, you can book online without picking up the phone. That's a big part of what makes the Relay Standard different: book in a tap, no phone tag. Pick your time, tell us what's going on with your system, and confirm. A live coordinator from the Marietta team reviews every booking before it locks in, so a human being is still checking that the time makes sense. If you'd rather talk first, call (229) 514-0545.
Our normal hours are Monday through Friday 7:00 AM to 7:00 PM, plus Sundays 7:00 AM to 7:00 PM. We do not overpromise arrival windows we can't hit. What you get is a live arrival time you can track on your phone. Availability changes day to day depending on how full the schedule is, so the fastest path is to book online or call (229) 514-0545 and see what's open. If you're in Marietta, Smyrna, Kennesaw, or nearby, we'll tell you honestly what today looks like.
We serve Marietta and the surrounding metro area, including Douglasville, Decatur, Powder Springs, Vinings, Fair Oaks, Smyrna, Kennesaw, Mableton, Acworth, Woodstock, and Austell. If you're inside that footprint and your AC just quit, we'll get to you. If you're on the edge of it, call (229) 514-0545 and we'll tell you straight whether we can take the job.
The rule of thumb we use: if the repair costs more than a third of the replacement cost and the system is over 10 years old, replacing usually makes more sense. If the repair is a capacitor and the system is 6 years old, repair it. The wildcard is the compressor. A failed compressor in an older R-22 system almost always means replacement, because refrigerant costs make the repair a bad bet. We'll show you the numbers for both options in Marietta and let you decide with full information.
Brands & Parts FAQs
We work with Trane, Lennox, and Goodman equipment. Each has strengths. Trane is known for durable heat exchangers and tight quality control. Lennox builds some of the quietest and most efficient units in the game. Goodman offers rock-solid reliability at a friendlier price point. We also service Rheem systems regularly, since they're common throughout Cobb County. The best brand is the one sized and installed correctly. A Goodman installed perfectly beats a Trane installed sloppily, every time.
We service every major brand found in Marietta homes, not just the ones we install. That includes Trane, Lennox, Goodman, Rheem, Carrier, York, Bryant, and older units that are no longer manufactured. The fundamentals of an HVAC system don't change that much between brands: they all move refrigerant, move air, and reject heat. What matters is the person diagnosing it. Our techs are trained across the major platforms. If we can't get a proprietary part, we'll tell you that on the first visit.
Usually not. Off-brand capacitors are the classic example. A generic capacitor might save you $40 on a repair and fail again in eight months. The branded capacitor that the manufacturer specifies may last five years. We use manufacturer-approved parts on every repair unless you specifically request otherwise. It costs a little more up front and saves you a second service call. In Marietta, where summer heat loads are brutal, the stress on parts is real. Buy the part that's built for the job.
SEER2 is the measure of cooling efficiency that went into effect in 2023. It measures how much cooling you get for each watt of electricity. A higher SEER2 means a lower Georgia Power bill. The current minimum for new systems in the South is 14.3 SEER2. Going up to 16 or 18 SEER2 costs more upfront but pays back over the life of the unit, particularly with Marietta's long cooling season. We'll show you the operating-cost difference between efficiency levels when we quote your system.
Every 30 to 90 days depending on the filter type and your household. A basic 1-inch fiberglass filter needs replacing monthly. A 4-inch pleated media filter can go 90 days. If you have pets, allergies, or live near active construction in West Cobb, replace more often. A clogged filter starves the blower, reduces airflow, and makes the whole system work harder. It's the single cheapest thing you can do for longevity. And no, a dirty filter is not a repair. It's why your coil is freezing.
Licensing & Insurance FAQs
Every pro working under our name is required to hold the license and insurance the state requires. That's a condition of carrying the Halden Heating and Air name and working to the Relay Standard. We're an independently owned and operated local business in Marietta, backed by an established brand. You can ask to see credentials at the door and your tech will show them. No one works on your system under our name without that baseline.
We use both, and we're upfront about it. What we require of everyone is the same: proper licensing, proper insurance, and the Relay Standard on every job. That means written pricing before work starts, photos before and after, and a digital invoice you can pay from your phone. The person at your door in Marietta is accountable to that standard, whether they're on our payroll or a contracted pro we know and trust. If a job has an issue, the fix runs through Halden Heating and Air Marietta.
For a full system replacement, a permit is typically required by Cobb County and the City of Marietta. We handle the permit application as part of the installation quote. For repairs like a capacitor or a contactor, no permit is needed. The line is generally: if we're changing out a major component or the whole system, the jurisdiction wants to know. We include permit fees in your written price so there's no surprise line item at the end.
Ask for license and insurance, then ask for a written price before any work starts. If either answer is vague, that's your answer. Read a few reviews but don't chase a perfect five stars, because no company is universally loved. Then ask what happens if the repair doesn't solve the problem. A good company has a clear answer. A bad one mumbles. We tell every Marietta homeowner the same thing: the company that's transparent about pricing is the company that's transparent about everything else.
Emergency & Response FAQs
We're open Monday through Friday 7:00 AM to 7:00 PM, and Sundays 7:00 AM to 7:00 PM. When you're in that window and your AC is down on a 95-degree Marietta afternoon, we move fast to get there. What we don't do is claim a 24/7 hotline we don't staff. When you book or call, a live coordinator checks the real schedule and gets you the soonest honest time. Call (229) 514-0545 and we'll tell you exactly what's available.
Check the thermostat settings first, then the air filter. A clogged filter is the most common cause of warm air, because it freezes the evaporator coil. Set the fan to "on" if the coil is iced over, which helps thaw it while you wait for a tech. Check that the outdoor condenser is running and that no breakers are tripped. Then call (229) 514-0545. Don't run the system on a frozen coil for hours. The thaw and diagnosis only work properly once we're there.
No. A screeching or grinding sound usually means a motor or compressor issue. A hissing sound can mean a refrigerant leak. Running it in either case risks turning a $300 repair into a $2,000 one. Shut the system off at the thermostat and call us. Electrical components and high-pressure refrigerant lines are not DIY territory. In Marietta's summer, it's tempting to push through one more day. That's when small problems become big ones. Don't let a noise ride.
Warranty & Guarantees FAQs
The Relay Visibility Guarantee is the promise every Halden Heating and Air location works to: total visibility on every job. That means a live arrival time you can track to your door, photo updates of the work before and after, a written price before anything starts, and a digital invoice you can pay from the link. You always know who is coming, when they'll be there, and what it will cost. It's not a parts warranty. It's a standard of doing business that applies to every visit.
Yes. Repairs are warrantied on parts and labor, with the exact coverage stated on your invoice before you pay. We don't bury warranty terms in fine print or make you call a national line to figure out what's covered. If a part we installed fails within the stated period, we return and fix it. The terms vary by part and manufacturer, so ask your tech for the specific coverage window on your repair. You'll see it in writing along with your price.
Most new systems from Trane, Lennox, and Goodman carry a 10-year parts warranty when the system is registered within 60 days of installation. That covers the compressor, coils, control boards, and other major components. It does not cover labor, which is why installation quality matters so much. A properly registered system protects the expensive parts for a decade. We complete the registration on every install so you don't lose coverage for missing a deadline.
