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. We guarantee you the best trained techs in the industry - NATE and EPA certified, background checked, drug-tested, and trained in building science.
We happily provide free estimates for all system replacements, while service/repair appointments include an $89 diagnostic fee to thoroughly determine any system issues. All service and repairs requires payment upon delivery of service, and, if paying in cash, technician may not have exact change. Online invoicing is available for convenience at time of delivery.
Many heating & air companies will simply give you an estimate to replace your current HVAC system, like for like. They don't take the time or may not even be trained to properly fit the best heating system or air conditioning system for your house and budget. An oversized HVAC system cycles on and off frequently, doesn't remove humidity from the air and kills your energy savings.
Need air conditioner repair service? At Holtkamp Heating & Air, we're always here to provide fast, efficient and affordable service for all brands of equipment. If you still have a problem and need our 5 Star air conditioner repair service, you can get a quick estimate below. Our friendly, licensed technicians are the very best in Gwinnett County and beyond.

AC wasn't working. $99 to come out (I live 5 minutes from their office). Technician shows up, hooks some equipment up to the condenser, but no hoses or manifold. Says he thinks the coils are just dirty, but there could be more. He won't know until after he cleans them. It'll be $125 to clean them. Uses my hose and does what appears to be a very thorough job spraying my condensers.

Still not cooling well. Goes into the attic to check the furnace. Says a sensor bulb is not attached correctly and he'll attach it for free. So far, so good. Attaches the bulb, goes back out to the condensers and comes back and says I need some refrigerant, but he can't add it if he thinks it's leaking. Wants to do a leak check by just adding nitrogen and looking for the leak for $135, but if he can't find it that way, he'll need to use an electronic device to find it and that will be an additional $390.

After that, it's $200 for the first pound of refrigerant and slightly less for additional! I can see where this is going so I told him no thanks. They started with small numbers and are just going to keep running it up. $200 for a pound of refrigerant is robbery! I called several places today, most quoted me $60 and the place I settled on is going to charge me $50.

Thank you Jesus that my a/c is back on. and thank you Holtkamp. Brandon wasn't just "on time, " he was early! and he quickly identified the blown capacitor and fixed it. It was a hot weekend and now we are cool in body and minds thanks to Holtkamp. this is the first time we had to use them for a repair but for 15+ years they have provided maintenance and it is a pleasure to write this review for a company that does such excellent work.

Everything I could've asked for and more. Got a walk through of my system quickly diagnosed the problem and explained what we needed to do. He got the part and installed it in less than 24 hours. Both Brandon and this company are truly amazing.

They installed a gas furnace at my home and were responsive to my wants and needs. They were professional and understanding of my concerns. The work was performed in a timely manner and was done very professionallly. Angelo, Ross, Jeff and Alex are an asset to the company. I chose Holtcamp as my installer because they instilled confidence in their approach to business.

I had received projected install prices from 3 other companies, but chose Holtcamp over them because the other companies just did not give me the feeling that I was getting the whole picture. I am very satisfied with my choice and hope to be a client of Holtcamp for many more years.

A+ Company that provides A+ Service I've been using Holtkamp for several years now for all of my HVAC needs. They have always exceeded my expectations and provided me with excellent service. I've used a few different companies in the past and no one comes close to matching what Holtkamp provides. They absolutely have me as customer for life. My favorite technician is Jared.

He is a really friendly guy and always makes sure to answer all of my questions that I have. He goes through all of his work that's performed step by step. I always feel confident that he's taking excellent care of my systems. I ask for him by name each time! -Colin T. Lacy (Suwanee)

Mr. Holtkamp is truly a friendly, thorough, efficient technician. I feel that the service he provided has a sense of personal and professional touch rather than just a job to fix my heating system. He has a great sense of humor and is a down to earth person to talk to. He went above and beyond not only fixing my heating system but also helped me fixed several electrical outlet problems that I have in my house.

The job he did not only bring warmth back to my house but also warm our hearts with his impeccable service. I highly recommend him to anybody who needs heating service repairs in their homes. Great job!

What a great company. I've had a service contract with Holtkamp for several years. My 18 year old system made a final gasp last week when my wife tried to knock the chill out of the house. Repair of the old system didn't seem prudent. This happened on Tuesday. Before the end of the day on Friday I have a brand new system in place. Thanks Holtkamp. Excellent, timely, professional service.
