A heat pump is one of the smartest investments a Georgia homeowner can make. It heats your home in winter, cools it in summer, and does both more efficiently than almost any other system out there.
But when something goes wrong — or when it’s time to replace an aging unit — you need a team that really knows heat pumps inside and out. That’s exactly what you get with Holtkamp HVAC & Plumbing.
We’ve been servicing, repairing, and installing heat pumps for Grayson homeowners since 1996. Our NATE-certified technicians understand how these systems work and how to keep them running at their best — year-round.

What Is a Heat Pump and How Does It Work?
A heat pump doesn’t create heat the way a furnace does. Instead, it moves heat from one place to another — pulling warmth from the outdoor air in winter and pushing it inside, then reversing the process in summer to cool your home.
This makes heat pumps incredibly efficient. Because they’re moving heat rather than generating it, they use significantly less energy than traditional heating systems. In a climate like Gwinnett County’s — with mild winters and long, hot summers — a heat pump is often the most cost-effective choice for year-round comfort.
Our Heat Pump Services
We handle every aspect of heat pump care — from emergency repairs to full system replacements.
Heat Pump Repair
Is your heat pump blowing lukewarm air, running constantly, icing up, or making a strange noise? These are all signs something needs attention. Our technicians diagnose the root cause quickly and fix it right — without unnecessary parts or guesswork.
Common heat pump repairs we handle:
- Reversing valve failure — the part that switches between heating and cooling modes.
- Refrigerant leaks — low refrigerant causes poor performance and can damage the compressor.
- Frozen coils — often caused by airflow issues or refrigerant problems.
- Compressor issues — the heart of the system, and one of the most critical components.
- Capacitor and contactor failure — common electrical issues that prevent the system from starting.
- Thermostat or control board problems — when the system won’t respond correctly.
- Defrost cycle issues — especially important during cold weather.
Heat Pump Installation
If your heat pump is more than 10–15 years old, or if repairs are becoming frequent and expensive, a new installation is often the smarter move. A modern heat pump is dramatically more efficient than older units — and can significantly lower your monthly energy bills.
We install all major brands and are proud Trane dealers. We’ll help you choose the right system for your home’s size, layout, and budget — then install it correctly so you get the full benefit of your investment.
Heat Pump Maintenance
Annual maintenance is the best way to prevent breakdowns and keep your heat pump running efficiently. Our tune-up covers a full inspection of both the heating and cooling functions, refrigerant check, coil cleaning, electrical testing, and more.
We also offer our System Care Program — a maintenance membership that includes annual tune-ups, priority scheduling, and discounts on repairs. It’s one of the easiest ways to protect your equipment long-term.
Signs Your Heat Pump Needs Attention
Not sure if it’s time to call? Here are some signs your heat pump isn’t performing the way it should:
- It runs almost constantly but the house never reaches the set temperature.
- The system is stuck in heating or cooling mode and won’t switch.
- Ice has formed on the outdoor unit (outside of normal defrost cycles).
- You hear grinding, rattling, or squealing sounds from the unit.
- There’s a noticeable jump in your energy bill without a change in usage.
- The air coming from your vents feels weak or room temperature.
- The system turns on and off frequently — known as short cycling.
Any of these is a sign to call a professional. Catching issues early usually means a simpler, less expensive fix.
Is a Heat Pump Right for Your Home?
Heat pumps work especially well in Georgia’s climate. Here’s why they’re a great fit for Grayson homeowners:
- Gwinnett County winters are relatively mild — perfect for standard heat pump operation.
- The long cooling season means you’ll benefit from the efficient air conditioning side too.
- Modern cold-climate heat pumps work even when temperatures drop below freezing.
- Dual-fuel systems pair a heat pump with a gas furnace — the best of both worlds.
- No need for gas lines — heat pumps run entirely on electricity.
Not sure if a heat pump is the right call for your specific situation? We’ll give you an honest, no-pressure recommendation based on your home, your usage, and your budget.

What Your Neighbors Are Saying
“Reached out to Holtkamp early in the morning. They responded quickly and Hunter arrived approximately an hour after my initial call. He had everything needed on hand, explained the repair process and finished the job in under an hour.” — Steve D.

Heat Pump Questions We Hear All the Time
Why is my heat pump blowing cold air in heat mode?
This is one of the most common heat pump complaints in winter. It could be a refrigerant issue, a failed reversing valve, or simply the defrost cycle running (which is normal and temporary). Our technicians can quickly identify the cause and tell you what’s needed.
How long does a heat pump last?
Most heat pumps last 10 to 15 years with regular maintenance. Some last longer. If yours is approaching that range and needing frequent repairs, it’s worth having a conversation about replacement.
Can a heat pump work in very cold weather?
Older models struggled below about 35 degrees. But modern cold-climate heat pumps are built for much lower temperatures. We can help you choose the right model if cold nights are a concern.
What’s the difference between a heat pump and a mini-split?
A ductless mini-split is actually a type of heat pump — it just doesn’t use ductwork. Standard heat pumps connect to your existing ducts. Mini-splits are great for additions, garages, or homes without ducts.
