What a Humming Air Conditioner is Trying to Tell YouNormally, a properly functioning air conditioner makes occasional pops, hisses, rattles, and a quiet hum that shouldn't be a cause for concern. However, if you notice a loud humming or buzzing noise, your unit is probably malfunctioning. Several issues can cause a humming air conditioner. Let's take a closer look at them along with their solutions.

"We reached out to Hartman Brothers as our previous place was actually rude and acted like didnt care as we had an issue with the AC. Our systems at that point were about 14 years old. We got a quote from previous place and i about fell off my chair. Called Hartman Brothers and asked if they could provide a quote for us on both and in AC alone. Super impressed as Rick came out next morning. Looked at what we currently had and that same day had a complete quote to us. We were scheduled for May 26 install however they had a cancellation and came out May 17. Both techs were super amazing. Talked with us with everything and answered all of our questions. They came out a little before 8am and everything was installed and working by 2pm. Cleaned up their stuff ( which was great as we have 3 dogs). Never have we experienced this type of professionalism from any company. We are all so pleased with Hartman Brothers including Vicki in the office. She was great helping me and explaining the maintenance agreement. If you ever need a great team you wont be disappointed with Hartman Brothers ! We thank you all for helping us and doing a great job. It was also great we kept it local as well. Glad to be a part of the Hartman Brothers family now ! Thank you again."

"Josh at Hartman Brothers did a good job. He quickly figured out the problem and got it fixed for 1/3 the cost I was expecting! He did not "find" problems or try to get us to upgrade, just did exactly what we needed him to do. I would strongly recommend calling Hartman Brothers for installing or repairing your AC/Heating!"
