Is It Time to Replace Your AC System?
Sometimes it’s obvious — the system stops working completely. But often, the signs are more subtle. Here’s how to tell if a new installation makes more sense than another repair:
- Your AC is 10 to 15 years old or more.
- You’ve had multiple repairs in the past few years and the bills are adding up.
- The house never really feels cool, even when the AC runs constantly.
- Certain rooms are always hot no matter how low you set the thermostat.
- Your energy bills have been climbing without any change in how you use the system.
- Your system uses R-22 refrigerant, which is now phased out and very expensive to service.
- The unit makes loud or unusual noises that keep coming back.
Not sure which way to go? We’ll give you an honest answer. If a repair makes sense, we’ll say so. If a replacement will save you more money over the next few years, we’ll walk you through the numbers.
Types of AC Systems We Install
Every home is a little different. We install a variety of cooling systems so you get the right fit — not just the easiest option.
Central Air Conditioning Systems
The most common choice for Georgia homes. A central AC connects to your existing ductwork and cools the entire house evenly and efficiently. We install high-efficiency models that can significantly reduce your summer energy bills.
Heat Pumps
A heat pump cools your home in summer and heats it in winter — all in one system. For Gwinnett County’s climate, it’s one of the most efficient and cost-effective options available. We install both standard and cold-climate models.
Ductless Mini-Split Systems
No ductwork? No problem. Mini-splits are perfect for room additions, converted garages, sunrooms, or older homes without ducts. They’re quiet, efficient, and give you individual control over each zone.
Dual-Fuel Systems
A heat pump paired with a gas furnace for backup. The system automatically chooses the most efficient option based on outdoor temperature. A great solution for homeowners who want the best of both worlds.
Two-Stage & Variable-Speed Systems
These advanced systems adjust their output based on how hot it is outside — running at lower capacity on mild days and full power when it’s really hot. The result is better comfort, lower humidity, and less energy use.
Authorized Trane Dealer in Grayson
Trane makes some of the most reliable, energy-efficient AC systems available — and we’re a proud authorized Trane dealer. That means you get:
- Access to Trane’s full lineup of cooling systems, including high-SEER models.
- Factory-backed manufacturer’s warranties properly registered in your name.
- Expert guidance on which Trane system fits your home and your budget.
- Confidence that the system is installed to Trane’s exact specifications.
We also install and service all other major brands — Carrier, Lennox, Rheem, Goodman, Daikin, and more. If you already have a preferred brand or a system you’re happy with, we’ll match it.
Our AC Installation Process — Step by Step
Here’s exactly what happens when you choose Holtkamp for your new AC installation:
- Step 1 — We visit your home and perform a proper load calculation based on your square footage, insulation, windows, and layout.
- Step 2 — We recommend the right system — sized correctly for your home. An oversized or undersized system causes major problems down the road.
- Step 3 — We give you a clear, detailed written quote. No hidden fees. What we quote is what you pay.
- Step 4 — We schedule installation at a time that works for you.
- Step 5 — Our NATE-certified technicians remove the old system and install the new one cleanly and carefully.
- Step 6 — We test the system thoroughly — including airflow, refrigerant levels, thermostat calibration, and temperature output.
- Step 7 — We walk you through the new system, show you how to use any new features, and register your warranty.
Most standard installations are completed in a single day. We clean up after ourselves and make sure you’re fully satisfied before we leave.
Our Comfort Match Warranty
We stand behind every installation with our Comfort Match Warranty. If your new system isn’t cooling your home the way we promised, we’ll come back and make it right — at no additional cost to you.
This is something most HVAC companies don’t offer. It’s our way of saying we’re accountable for the work we do — not just during the installation, but long after we’ve left your home.

Questions About AC Installation in Grayson
How long does an AC installation take?
Most installations are completed in one day. If your home needs ductwork modifications or other prep work, it may take a bit longer. We’ll give you a realistic timeline before we start.
What size AC system do I need?
Size is determined by a load calculation — not just square footage. Ceiling height, insulation, window placement, and how many people live in the home all factor in. We do this correctly before recommending any system.
What SEER rating should I look for?
SEER (Seasonal Energy Efficiency Ratio) measures how efficiently a system cools your home. Georgia now requires a minimum of 15 SEER2. Higher SEER ratings mean lower monthly bills — we’ll help you find the right balance between upfront cost and long-term savings.
Will a new AC system really lower my energy bill?
In most cases, yes — especially if your current system is older. Modern high-efficiency systems can use significantly less energy to cool the same space. We can give you a realistic estimate of the savings based on your specific home.
What happens to my old system?
We remove and properly dispose of your old equipment. You don’t have to worry about a thing.
