AfterAC Repair & Installation Near You in Marietta, GA
If your AC just quit on a 94-degree Marietta afternoon, here’s the short version: Halden Heating & Air repairs and installs air conditioning systems across Marietta, and we can usually get a background-checked technician to your door the same day. Call (229) 514-0545 and you’ll talk to a live person, not a voicemail tree. You’ll get a written price before any work starts, and you can track your tech’s arrival like a rideshare.
We’re an independently owned and operated HVAC company founded in 2004, part of the Relay Home Co. network. That means we run on The Relay Standard: book online, see who’s coming, and know the price before a single tool leaves the truck.
Fast, Local AC Repair & Installation
When your AC goes down in Cobb County heat, “soon” isn’t a plan. We answer calls 24/7 with a real person and schedule repairs with a live arrival time you can track on your phone. That’s not a four-hour window. It’s a name, a photo, and an ETA that updates as the truck moves.
Our technicians are background-checked, uniformed, and certified to work on major brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. They carry the parts most commonly needed for same-day fixes: capacitors, contactors, fan motors, and refrigerant. If your system is beyond repair, we’ll walk you through replacement options with the same upfront-pricing rule: written quote first, no surprises later.
Every repair in Marietta includes The Relay Visibility Guarantee. Before work begins, you get a written price. After the job, you get before-and-after photos. And every repair carries a written guarantee, backed by our 365-Day Done Right Promise. If the repair fails within the coverage window, we come back at no charge. No arguing, no fine print, no “that part wasn’t covered.” It’s automatic.
Here’s what to expect when you call (229) 514-0545:
- A real person answers, day or night.
- You pick a time that works, or we slot you in for same-day emergency service.
- You get a live arrival time and can track your technician to your door.
- Your tech diagnoses the problem, explains it in plain English, and hands you a written price before starting.
- You approve the work. The tech fixes it. You get photos and a written guarantee.
How Much Does AC Repair Cost in Marietta?
Most AC repairs in Marietta run between $150 and $500 depending on the part. A failed capacitor or contactor, two of the most common failures we see in Cobb County, usually falls on the lower end. A compressor or evaporator coil replacement runs higher. New AC installation in Marietta typically ranges from $5,500 to $12,000 depending on system size, efficiency rating, and ductwork condition.
Here’s a breakdown of common repair costs in the Marietta market:
- Capacitor replacement: $150 to $300
- Contactor replacement: $180 to $350
- Refrigerant recharge (topping off the coolant your system needs to produce cold air): $200 to $500, depending on refrigerant type and amount
- Condenser fan motor replacement: $350 to $700
- Blower motor replacement: $400 to $800
- Evaporator coil replacement: $1,200 to $2,500
- Compressor replacement: $1,800 to $3,500
Those are honest ranges, not bait. Before any work starts, you get a written price locked in. If the repair fails within the guarantee period, your second visit is free. That’s the 365-Day Done Right Promise from Halden Heating and Air Marietta.
Signs Your AC Needs Repair
You don’t need to be an HVAC expert to spot trouble early. Here’s what we tell our Marietta neighbors to watch for:
- Warm air blowing from vents when the thermostat is set to cool. That’s often low refrigerant or a failed compressor.
- Short cycling: the system turns on and off every few minutes. It’s usually a thermostat issue, a dirty filter, or an oversized unit.
- Weak airflow from your vents. Could be a failing blower motor or blocked ductwork.
- Strange noises: grinding, squealing, or banging. These are mechanical warnings, not personality quirks.
- Water pooling around the indoor unit. A clogged condensate drain line can cause water damage fast in Marietta’s humid summers.
- Electric bills climbing with no change in usage. An inefficient system works harder and costs more.
If you notice any of these, call (229) 514-0545. Catching a problem early in Marietta’s heat often means a $200 fix instead of a $2,000 one.
AC Installation in Marietta: What to Know Before You Replace
Replacing an AC system is a big decision, and Marietta’s climate makes it matter. Our summers run hot and humid from May through September, with temperatures regularly hitting the low 90s. A properly sized and installed system isn’t just about comfort. It’s about not paying Cobb EMC or Georgia Power more than you need to every month.
Here’s our installation process, step by step:
- Free in-home assessment. We measure your home, check your ductwork, and ask about hot spots, humidity issues, and your current energy bills.
- Written quote with options. You get multiple system options, from good to best, with honest numbers. No pressure, no “today only” pricing.
- You approve the plan. Only after you see the written price and understand exactly what’s being installed.
- Installation day. Our team arrives at the scheduled time, protects your floors, and completes the install in a day for most homes.
- Walkthrough and photos. We show you the finished work, explain your thermostat and maintenance schedule, and send before-and-after photos.
- 365-Day Done Right Promise. One full year of accountability on every completed installation.
We install and service all major brands, so if you already like your Carrier or Trane system, we’ll match it. If you’re open to options, we’ll recommend what works best for Marietta’s climate and your budget.
