After 7 years of service we were suddenly informed on the morning we are supposed to have an appointment with Casa mechanical that they will no longer be serviced in the unit at our address because the system was installed by somebody else. This makes no sense to me because the system they service prior to the installation was also installed by somebody else. I am also upset that this appointment was made with a month lead time and I am contacted only a couple of hours before our appointment is supposed to happen to tell me not only is it canceled but they're never coming back. I hired a house sitter to come meet Casa today that money has already been paid we are out of town and a family emergency. This is not how we do business this is unacceptable and my recommendation to anyone looking for an HVAC service is to look elsewhere so that you don't receive a nasty surprise like this. This is extremely unprofessional and disappointing.

I have a service contract with Casa Mechanical for my home units and my office units. Today the service tech did not wear a mask. With over one million cases of Covid in Texas he put my family and everyone at work in danger. He also broke the law that the governor imposed requiring the wearing of masks in work places.

These guys have the most chaotic system, dispatch, service, training, customerservice support. They installed our AC/Heater with the homebuilders 3 yrs ago. From the onset its been fubar from day one. Moved in AC didn't work. The fuse wasn't installed and turned on/checked properly. Every year for spring/fall maintenance its a hassle setting up a schedule. If its a gated community and they can't get in they say they tried, called you and then leave without word to reschedule. Your never notified when they are actually trying to get in so your left with their schedule time of 5 hour window to sit and wait all day. Finally I call to see what happened only to be told sorry you have to reschedule which of course is another department. And when you speak yo someone it seems like your bothering them. Well this happened too many times. Yesterday was the last I'll every waste our time with these guys. No show because they couldn't get in or reach/call my cell when they are there, which is BS since I sat here all day with charged phone at home taking off of work. Then very next day I see their van/technician servicing right next door, unbelievable. Every technician is trained and taught differently because every one the last 3 years has different ways of working your system properly.

I am very disappointed and unhappy with CASA. I had a lightning strike hit my house and it affected my heat/AC system. I asked CASA to look at it and they said I needed a complete system replacement ($4,500). My insurance company had an independent inspector look at it and determined that the only thing wrong was the Defrost Control Board - total cost less than $500. I didn't receive a satisfactory explanation for why they said my entire system was bad and have never received a call back from their service manager.

My just built home Hvac was done by Casa.. and I am extremely disappointed! First cold spell last year my heat did not come on, after the service man came, he confessed that the fan CUT THE WIRING!!! So he just taped it up, and it started back up. Now today, when it's 43 degrees, heat not working again... so I call, the service rep was extremely derisive and would not even try to get someone out today...I am a school teacher and essential worker, and can not take off, so she says soonest she has is Thursday , and could not put me for after 4... and no weekends! There was no effort, did not try and call a tech in my area to even see if it was possible. So non honoring of warranty, no possible flex or effort put into getting my heat on after their unit has history of issues, and workmanship that resulted in documentation of cut electrical wires.. And if I wanted service call it's 88 dollars for the first 15 minutes?!?! And 22$ every additional 15 minutes?!?! Seriously?!?! Beware!

Good clean job of replacing a complete A/C system and furnace 10 days ago. Work masks and shoe coverings. Minor glitch resolved while they were here. All around excellent work.

I needed a new air conditioner. Talked to several large HVAC contractors. Selected Csa--good price quote, good sales rep, and good product. They came on schedule and finished in a day--all went well and it was VERY nice to get the ari back on. Love the new multi speed AC, It is worth the extra money. Extremely quiet--and the fan is so smooth that there is no noticable forced air blowing on you when the unit is on. And the dehumidifier does seem to work--the air seems a little crisper. Nice.

INCONSIDERATE CON ARTISTS.

i was working on a jobsite with only myself and my co worker, no home owners or other crews around. I walked around the house to our work truck for just a few minutes to get the material i needed to finish my task at hand, and when i came back my drill was gone as well as the casa mechanical truck that parked in front of our jobsite right before i walked around the house. I called the main office and informed me that the employee saw my drill, and did NOT see anyone else at the jobsite, but didnt take it. So in conclusion they said there is nothing they can do it about it.
Apparently the man in charge, Jim Stokes will not even return a call. Very disappointed to hear that several other employees from various companies have similar stories involving casa mechanical. BE AWARE.

Did the plumbing and HVAC on our new construction. Talked a good game regarding their customer service but that disappears once they're paid. Save yourself some grief and look elsewhere.

About two months ago I had intermittent problems with my water heaters that Casa Installed 3 years ago on the original build of the house. They came out said two of the elements were bad and replaced them. Thinking everything was good a couple weeks later the water heater breaker kept popping. Finally today I called them after I pulled the cover off the element and I found out the HOT wire was not even attached. I called Casa and they refused to come fix it. I guess I will find another plumber in the future.
