Andrew Hartley (NYCKID)

I had a great experience with A1. They came out to look at an issue with my furnace and were very professional and honest throughout the process. After inspecting the problem, they gave me a fair price for the repair and clearly explained what might need attention in the future. I really appreciated that they didn’t try to upsell me on anything unnecessary and took the time to answer my questions. It’s hard to find companies that are both knowledgeable and trustworthy, and this was definitely one of them. Highly recommend!

I could not be happier with the service I received. I needed a new furnace fast as it is in single digits. They were able to put in new for me within a day of mine dying. Only took them like an hour and a half too! My house is warm and I so pleased. The installers were fast, professional and kind. I will be calling them for all future problems! And the warranty is awesome too. Thanks A1!

Furnace went down on me around christmas time. I tried to DIY it myself at first, when I should have just called A-1 Milwaukee heating and cooling. I went about 7 days waiting on a part to try to fix it myself. They came out after I could not fix it myself. They replaced my whole furnace, fixed all the issues the old furnace had with being installed wrong. They came out on a friday. And were able to install and have it all fixed by noon on a saturday. They were straightforward with me about everything. And even worked with the pricing with me knowing I was on a budget. For them to install a brand new furnace, move the gas lines install new duck work i didnt have to break the bank. I should of called them from the start but thought I knew what needed to be fixed but it was such an old furnace. Great employees owner everything was great from communication to politeness. Now my family can stay warm. And everything is warrantied. Thank you again for starting my new year off right. I appreciate everything.

My experience with A-1 was very smooth. We had some inspection repairs in a house that we have for sale that needed to be done right away. I called them and they had a technician give a quote the same day and they finished the job next day which was running an air duct to a second bathroom because there was no heat source. Good communication and good work!

I called A-1 on Monday and they would have sent someone out the following day but due to my schedule we decided on Wednesday. Punctual and efficient. Before the end of business Wednesday I had my quote and decided to move forward. The crew arrived a little early, which was great. I had heat in less than 6 hours. I am pleased with everything. Mike was very honest when he gave me my quote. Not the cheapest and not the most expensive but affordable. I would definitely recommend A-1 to anyone in need of assistance. Thanks again to Mike and the crew. Amazing job from start to finish!
