If you have a problem with your tankless water heater and radiant heater system, do not hesitate to call. Gerald (the owner) is outstanding - he is kind, extremely knowledgeable, and helps walk you through your system to not only understand any issues you may be having now but also help you maintain it in the future. In a world where you aren't sure who you can trust/rely on, you can count on Gerald and his team!

My dryer was taking far too long to finish a cycle, and i realized something was wrong. I booked this contractor to come and check what was happening; they found out that it was blocked, and they unblocked it in no time. I recommend them.

Great service and information by Derick today. I am HERS RATER and I love referring installers and new HVAC companies to them!

Best one stop HVAC suppliers in business! Tools equipment parts all in one, multi-brand parts supplier.
When the others branded companies can’t, Johnstone is your best resource. The best in HVACR Contractor wholesale.

If you're not a contractor these guys don't want your business. It looks like a store but evidently is not; they told me they couldn't sell to me and sent me up the street to pay for the part (they wouldn't even tell me how much it would cost before I drove to the other location). After standing in line twice at Ace Hardware (once in main line then was sent to talk to manager) I found out they wanted twice as much for the part as what I ended up getting it for. All of this wouldn't have been the end of the world if they weren't so rude about the whole thing once finding out I wasn't a contractor. If you're a contractor they are probably fine, if not - don't bother going there.

I have an EPA 608 certification and I called Johnstone to get a quote on a heat pump system. They refused to give me a quote unless I have a C-20 license. They won't even sell to general contractors. The whole point of getting A universal 608 is so you can purchase equipment to do repairs.

I bought a thermostat from them. A friend installed it and I just needed help reprogramming it. My friend who installed it took about one minute to program it but he has moved away. There are no directions and when I called this company where I bought it they were rude and condescending. I am 73 years old and the guy who was in the parts department said I would need a technician (about 100+ dollars) I am a senior and need 2 minutes of help to do something he said was simple and just go on line to learn how. I don’t have a computer. It verges on elder abuse. I paid good money to get the Emerson programmable thermostat from Johnston. But they won’t give an elderly woman 2 minutes of their time! I will never do business with them again nor recommend them to any senior. It’s 2022 folks and treating a senior like that is horrible business policy and practice.

This place has it all. Whenever I need something I call Johnstone Oakland. They always have it in stock and at a good price. Can't beat that!

Great experience with Oakland team, they always smiles and ready to help. They are great than concord store when it comes to customers experience

Oakland Heating & Cooling Service provided exceptional service. The technician was punctual, polite, and very knowledgeable. He repaired the system efficiently and explained everything clearly. The cost was fair, and the service quality was outstanding. Oakland Heating & Cooling Service remains my trusted HVAC contractor.

Oakland Heating & Cooling Service truly impressed me. The technician arrived early, handled everything professionally, and cleaned up after himself. He was courteous and very knowledgeable. The pricing was transparent, and the AC is now working perfectly. I’m very satisfied with the experience. Oakland Heating & Cooling Service is absolutely worth every penny.

Their emergency HVAC service showed up when others wouldn’t. I really appreciated that commitment.

The AC duct cleaning service was exactly what we needed for our musty vents. They sanitized everything and removed all the hidden buildup. Now the air smells wonderful and our home feels much healthier.
