The crew was meticulous when cutting into the hard wood floors as well as incorporating the existing old, gravity furnace opening, to the new system in order to not have to cut into my walls. Other than turning on the system and enjoying the heating and air, I would not have known they had been in my home. From my first call to when the crew completed the installation, the job was handled in a completely professional manner. The units they installed operate so quietly, I don’t know when they are on! And working with the owners Doug & Donna, was a complete delight! Because of their professionalism at my home, ACS now does all the repair and maintenance work for all the properties that I manage. From a large industrial building to a small rental, all I have to do is place a phone call and they take care of the rest. With total confidence, I highly recommend AC Systems.

ACS has worked with us since we first purchased our present home in 2006. Successively they have installed a new HVAC unit, sealed and replaced older less efficient ducting, and most recently installed a zone system. Doug has always been very prompt with a quotation and ready with answers to many questions we had about cost, how the work would be done, and on what schedule. The technicians who performed the work were uniformly very polite, took extra care to not bring dirt into the house, and were very careful about doing first class work. The materials and equipment used are high quality, resulting in what in the long run will be the most economic cost. Doug and Justin will be at the job to inspect the working being done. We also rely on and recommend ACS for seasonal inspection and testing of our HVAC system. Donna, the owner, Doug and Justin, and their technicians are a top drawer operation.

Just a quick note to thank you for the recent A/C installation. Both Darren and Justin were very thorough with the installation and took the time to explain the process to me.

This morning I turned the heater on to remove the overnight chill. I noticed a remarkable difference in the duct output, since Darren had replaced and sealed the duct extension to my unit. GOOD JOB!

I’m looking forward to the HOT summer and possibly lower energy bills………thanks to your help!

P.S. I just want to tell you that the building inspector was here this morning and signed off the job. He told me that whoever installed this unit “DID A GREAT JOB”.

We couldn’t have made a wiser decision than to choose ACS to replace our 30+ year furnace and air conditioning system. We met with three different companies, all with personal recommendations, and ACS was, by far, the most knowledgeable, professional and affordable, apples for apples. The installers were courteous and impeccable. ACS was terrific in facilitating rebates, one for which we had been unaware we were even qualified! The County Inspector passed the installation with flying colors. For superb quality of service and equipment, you can be confident choosing ACS.

I recently had ACS install a Carrier HVAC system (furnace+A/C) in my house. From start to finish, they did a wonderful job.

Bid: After my initial call, Doug and Justin promptly came out to estimate the job. They arrived on time and quickly and efficiently examined the entire existing system including existing ducting under the house and in the attic (other contractors were not as thorough in getting an idea of the existing state of the system). Using what they learned, they prepared an initial bid that clearly explained our options and what each option would cost. They also adjusted the bids several times to incorporate our feedback.

Install: ACS is a union shop and the installers, Darren and Michael, were friendly, well-prepared, and really knew their stuff. They did a great job, including making sure that the house (particularly the hardwood floors) was kept as debris and damage-free as possible while flawlessly installing the system. They showed up when they said they would and worked hard all day to get the system finished by the projected deadline. Two great guys. On final inspection, the install met nearly all of the county inspector’s qualifications. Darren and Michael came immediately (i.e., the next day) to resolve the one or two trifling details that the inspector found. In addition to setting up reasonable financing terms and preparing the paperwork for us, Doug came back out after the job was finished to help with preparing refund claims for the union and PG&E.

Overall: A contractor that operates how contractors should operate; on time, on budget, professional, courteous, and knowledgeable. I highly recommend.
