EXCELLENT Based on 167 reviews Craig Wilson2025-07-09Trustindex verifies that the original source of the review is Google. Jose was a really nice guy who explained things in a very easy to understand way. He took extra time in cleaning our units and I appreciate how cool he was with our barking dog. Padgett E2025-07-02Trustindex verifies that the original source of the review is Google. Jose came to clean our AC unit. He was prompt, courteous and knowledgeable! Brett Czech2025-06-30Trustindex verifies that the original source of the review is Google. Bob has always been great to work with—punctual, professional, and incredibly efficient every time. Scheduling service is simple and stress-free, and they even call with reminders (how great is that?). Paying and getting receipts is just as easy. Any work that is suggested or completed is explained and Bob is straightforward with letting you know when something is recommended, needed, or not needed. You can tell this is a family-owned company because it shows in the level of care and pride they take in their work. They genuinely value their customers and it comes through in every interaction. Highly recommend! renee carreno2025-06-30Trustindex verifies that the original source of the review is Google. Bob and his company are the best! Honest, best priced and come out right away when called. We were referred by a friend/neighbor and couldn't be more grateful. We have referred him to everyone we know!

He provided information about my options as well as a thorough explanation about coolant, age, wear/tear of my AC unit. I would highly recommend CustomService. Regina Ferguson2025-06-20Trustindex verifies that the original source of the review is Google. 12/7/2024 Excellent service again for a sound we heard from the furnace. Sent a text to Bob and he responded immediately. Said he could come out tonight. I told him there was no rush. I received a text shortly after our conversation saying a technician would be there the next day between noon and 2:00. Like clockwork he sent me a text around 12:30 saying he was on his way. He arrived shortly after, and fixed the problem. We are members of their monthly subscription so we have the assurance of not being charged for service visits and basic maintenance. I am extremely happy with the service we’ve received for the past four years. I’m positive that Customer Service has saved us a lot of money by providing seasonal maintenance on our AC & furnace. (Original post)Bob has been servicing our HVAC system for the past few years and we have been and still are nothing but satisfied and thankful for the service he provides. My daughter has her own construction and service business and she agrees: “The price is excellent and the service is excellent.” I HIGHLY RECOMMEND Custom Service!! R A2025-06-12Trustindex verifies that the original source of the review is Google. Bob is wonderful! He checked all the systems related to the AC and then did the diagnosis test. Before doing anything he explained what the issue was and what other problems might be related to it. He went through the pricing and it's reasonable. He also explained how important it is to have the AC, furnace, and heating checking. Luckily, we only needed to replace the capacitor to our old AC. Highly recommended Custom Service Heating & Cooling! Amber Moore2025-06-12Trustindex verifies that the original source of the review is Google. Air conditioning went out the night before a 90 degree day. Once again Bob responded quickly, efficiently identified & fixed the problem and gave us helpful and economic suggestions for options moving forwardVerified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
