Having Albert from Zimmermann inspect my air conditioning and heating unit was a great experience. I have an old unit but Albert didn’t find any problems with it and he gave me the peace of mind that my equipment is working fine. He was very patient and answered all of my self maintenance questions and made sure I understood what I needed to do to keep my unit working optimally. I very much recommend Albert from Zimmermann for an honest, great quality inspection or to service your unit.
I am extremely satisfied with the services provided by Zimmerman. I recently had my A/C serviced by technician Jason who was prompt, personable and very professional. I have used Zimmerman Svcs for several years including a major sewer line repair (to fix a line break caused by another plumbing company) & have been pleased with the all the services provided. The office staff & technicians are always courteous & the prices charged are reasonable.
I recently had AC problems in June. A local company that actually installed it had come out at least 4 times in 1 year and still I was having problems. They wouldn't return calls, it was a horrible experience. I decided to call Zimmermann, Albert came out diagnosed the problem right away and it was completely fixed the next day and I haven't had any issues for the past month. Very competent, friendly everything had been covered under my warranty which was great, since I discovered the other company had been charging me when they shouldn't have. I will definitely be using Zimmermann if I have any other problems.
Noticed (83 Degrees and rising inside) A/C (outside unit) wasn't working. Called at 2:00pm (Labor Day). Albert, who was on call, arrived at 3:00pm. Replaced capacitor, checked out rest of the system and was complete by 3:30pm. Quick and responsive service. Just charged for service call as the rest was under warranty. Have used Zimmermann Services for going on 20 years now. Always excellent.
"We have used Zimmermann Services for all of our air conditioning, heating and plumbing needs for approximately seven years, since we stopped renting out our San Antonio residence. We have been extremely pleased with the timely and excellent services performed for reasonable prices, and the HVAC maintenance visit by Albert on 17July 2014 was a continuation of this high standard of excellence. I recommend Zimmermann highly to anyone looking for plumbing or HVAC services."
