As Georgia's #1 American Standard dealer, we provide award-winning air conditioning and furnace / heat pump repairs, replacement and maintenance to Gwinnett County and surrounding areas from our Suwanee headquarters.

Replacing or servicing your heating and air system is one of the largest investments you'll make in your home. How can we put your mind at ease that you've chosen the very best local HVAC company to bring your family comfort? By sharing ‘The Holtkamp Way', a list of guidelines that we've lived by every time we've been invited into homes just like yours for the past 20 years. Ready to get a worry-free estimate? We look forward to meeting you and putting our expertise to work to solve your comfort problems!

It's good to get as much life out of your heating system as possible, but wise homeowners know that it's much better to replace your older existing system with a new, efficient model before your old one kicks the bucket. By being proactive about your heating system replacement, you'll minimize any downtime between systems and start maximizing the energy savings you'll enjoy from your new furnace or heat pump. We're often asked why we repair all brands of HVAC equipment but only install American Standard HVAC systems.

Do you have an odd room in your house that's always a different temperature than the rest of your home? From sunrooms to basements, perhaps your existing air conditioner or furnace isn't providing a consistent level of comfort. Fortunately, we have a simple solution for your frustration: ductless, wall-mounted air conditioning units, also known as "ductless mini splits." These slim-profile indoor units attach to an outdoor unit through a small 3 hole for power and refrigerant lines. Just one outdoor unit can power up to 8 individual indoor units throughout your home or office.

If you think you're experiencing poor indoor air quality, you might be suffering from leaky ducts. What are the key symptoms? You might see lots of coupons and mailers from companies claiming to "clean" or "vacuum" your ductwork at low prices. However, if dust, allergens and contaminants made it into your ductwork in the first place, won't they come back if your ducts aren't properly sealed? If you invest in this temporary fix, the contaminants are going to come right back. In this video, Matthew provides his professional insights into duct cleaning vs. duct sealing.

Did you know that your air conditioning system was designed to have maintenance twice per year? Your membership in our Comfort Club includes your a/c and heating tune-ups, and will help keep your family comfortable all year round while protecting your investment in your HVAC system and providing incredible money-saving benefits.

This family owned business is wonderful. They do great work and are professional and attentive. We would recommend to everyone.

Holtkamp installed a new heating and air conditioning system for me 2 years ago. It was a seamless process, from choosing a system to the actual installation. Since that time, they have continued their excellent service while maintaining my system. So far everything has performed flawlessly. I highly recommend them and their great staff!

Approximately 16 years ago, after having a problem no other repair company could fix, we were lucky enough to find Holtkamp. The owner, Matthew, immediately knew a part replacement would fix this problem. Matthew Holtkamp values his clients and this is reflected in how each staff member treats you. If you have a problem or concern Matthew will make sure all equipment is operating correctly and you are happy. I can not say enough good things about the Holtkamp staff. From start to finish your experience will be perfection. Using Holtkamp is like having your own personal heat/air concierge.
