Pricing & Cost FAQs
Most HVAC repairs in Marietta run between $150 and $600, with diagnostic fees typically applied toward the repair if you approve the work. The final number depends on what failed. A capacitor swap is quick and inexpensive; a compressor replacement costs more. We give the price in writing before any work starts, so you're never surprised at the door. Call (762) 240-5599 for a free estimate on your specific system.
A full heating and cooling system replacement in Marietta typically falls between $6,500 and $12,500, depending on the size of your home, the efficiency level you choose, and any ductwork modifications needed. A simple furnace or AC swap lands on the lower end; a high-efficiency system with new linesets and air-quality add-ons lands higher. We provide a written fixed price before ordering anything.
An annual cooling tune-up in Marietta generally runs $89 to $180. It includes cleaning the condenser coil, checking refrigerant levels, testing the capacitor, and tightening electrical connections. You'll get a written report showing what was checked and what, if anything, needs attention down the road. Our technicians aren't paid on what they sell, so the report reflects what your system actually needs.
No. Estimates are free. When you call (762) 240-5599, we'll schedule a visit, assess your system, and hand you a written price before any work begins. That price doesn't change unless you change the scope.
Yes. Georgia Power and Cobb EMC offer seasonal rebates on qualifying high-efficiency heat pumps and air conditioners, and federal tax credits remain available for eligible ENERGY STAR systems. What you qualify for depends on the specific equipment and your home's setup. We'll check current rebates for your project and handle the paperwork.
If the repair costs less than a third of the system's replacement value and the unit is under ten years old, repair usually makes sense. If you're past twelve to fifteen years, facing a compressor or heat exchanger failure, or seeing repeated breakdowns, replacement is often the smarter money. We'll show you both numbers in writing and let you decide without pressure.
Service & Process FAQs
The technician inspects the system, diagnoses the issue, and shows you what they found before any repair work begins. You approve a written price first. Once you say go, the work happens right then if parts are on the truck. The Kingswell Way applies to every visit: price before the work, a real arrival window, a clean job site, and a written guarantee.
Most common repairs, like a capacitor, contactor, or thermostat replacement, are finished in under two hours. Repairs requiring parts that aren't on the truck may take a day or two, depending on local supply availability in the Marietta area. We'll tell you the timeline honestly, and we show up in the window we gave.
We give a real arrival window, not an all-day wait. When you book with Cold Harbour Heating and Air Marietta, our coordinator confirms your window and the technician honors it. If something shifts, we call before the window closes. It's one of the promises behind The Kingswell Guarantee.
For the first visit, yes. We need access to the system and the ability to show you what we found and get your approval on the written price. For follow-up work where you've already approved the scope, we can arrange access if you've made prior arrangements with our office.
Every professional working under the Cold Harbour Heating and Air name is required to hold the license and insurance their state requires. That's a network standard we don't compromise on. When a technician arrives in Marietta, you'll know who you're letting into your home.
Yes. Our maintenance plan includes a spring cooling tune-up and a fall heating tune-up each year, with priority scheduling and written reports after every visit. Homes on the plan tend to catch small problems before they become summer breakdowns in the middle of a Cobb County heat wave. Call (762) 240-5599 to see current plan pricing.
Brands & Parts FAQs
We service and install Trane, Lennox, Rheem, and Goodman systems. That covers the vast majority of what's installed in Marietta homes, from older builder-grade units to newer high-efficiency heat pumps. We don't push a single brand; we match the equipment to your home's size, ductwork, and budget.
We install Trane, Lennox, Rheem, and Goodman equipment, which covers the range from solid mid-tier value to top-tier efficiency. What matters more than the badge on the cabinet is the sizing and installation quality. A correctly sized, properly installed Goodman will outperform a poorly installed premium brand every time.
We source the correct OEM or equivalent parts for your specific system. For newer units under manufacturer warranty, we use warranted parts so your coverage stays intact. For older systems where OEM parts are discontinued, we'll tell you what the options are before we order anything.
Marietta's summer heat and humidity push systems hard, so longer runtimes in July and August are expected. But if your system is running constantly and barely keeping up, something's off: low refrigerant, a restricted filter, or an undersized unit. That's a call worth making before the system fails outright on the hottest day of the year.
Licensing & Insurance FAQs
Every professional working under our name is required to hold the license and insurance their state requires. In Georgia, that means licensed conditioned air contractors. You can ask for documentation at any time, and we'll provide it without hesitation.
Yes. The City of Marietta and Cobb County require mechanical permits for system replacements, and we handle the permit process as part of the installation. Your written quote includes permit fees where applicable. No shortcuts on paperwork; that's part of leaving the place cleaner than we found it.
The Kingswell Guarantee is the written promise behind every job: a written price before any work starts, a real arrival window, a clean job site, and a written guarantee on the work. If a repair fails inside the guarantee period, we come back and fix it at no charge. It's not marketing language; it's the standard our local team agreed to work to.
Emergency & Response FAQs
Our hours are Monday through Friday 7:00 AM to 7:00 PM and Sunday 7:00 AM to 7:00 PM. We're closed Saturdays. When your AC fails during a Marietta heat wave during those hours, call (762) 240-5599 and we'll get a technician to you as quickly as possible.
In many cases, yes. Our schedule fills quickly during the peak of Marietta summers and the first cold snaps of winter, so the earlier you call, the better your chances of same-day service. Call (762) 240-5599 and our coordinator will tell you the earliest available window.
If it's outside our hours, start with the simple checks: confirm the thermostat is set to cool, check the filter isn't clogged, and verify the breakers haven't tripped. Those three things resolve a surprising number of no-cool calls. If the system is still down, call us first thing in the morning at (762) 240-5599.
Warranty & Guarantees FAQs
Our workmanship is covered in writing under The Kingswell Guarantee. If a repair we made fails within the guarantee period, we come back and fix it at no charge. No deductibles, no service fees, no fine print. You'll receive the guarantee terms in writing alongside your repair or installation paperwork.
Yes. When we install a Trane, Lennox, Rheem, or Goodman system, we register the equipment with the manufacturer so your parts warranty is active. Most manufacturers offer a ten-year parts warranty when the system is registered promptly. We handle the registration and provide you the confirmation for your records.
The most common warranty killers are skipped annual maintenance, unlicensed installation, and using non-approved parts. Manufacturers require professional installation and documented upkeep. A maintenance plan keeps your records clean and your warranty intact. If you're unsure whether your current warranty is still valid, call us and we'll help you check.
