I've had an intermittent smell of gas since I purchased the house. Casa Mechanical did the original install. This, obviously, seems like an urgent issue. After speaking with the manager, a technician was sent by the house the next morning! They found it to be normal when the tankless water heater activates and not the result of a leak. The attention of the owner and manager to resolve our fears was amazing!

Casa is a terrible company to do business with. They do NOT care if they show up on time or at all. They will also charge you a premium for the work they do a shotty job on. Please refrain from doing business with these con artists. They sub out the work and don't follow up with the owner or builder and charge for trips that didn't happen or where work was not performed. Very disappointed, and hope builders quit doing business with them. They will also charge you for material they did not provide. Be very cautious because the people in the office have no idea what is going on in the field.

Really disappointed in this company. They installed all the plumbing for our new home in Sun City. Never bothered them until today when we had the sewer back up into our walk-in shower. When I called Casa Mechanical and explained our situation and that our home was just two years old they indicated our warranty had expired and even though I explained the emergency they said the best they could do was send someone out the next day.

Not really what I expected from the company that did our plumbing. I would not recommend them.

Hats off to Casa Mechanical!!! My sales rep Evan Young did a fantastic job helping me with my AC that stopped working during 100 degree weather! He installed 2 wall units in my house so I had AC until they were able to install (next day). His team - Paul, Mario and Wes were extremely friendly and helpful. They did an amazing job with the install!

Thank you Casa Mechanical team!!!

Since 2014 we've used casa mechanical for AC issues twice under warranty and once out of pocket. Never totally fixed our issues. Had a different company come out and they found that casa failed to put the cap back on when they filled it with Freon on their last visit. Unit was almost empty- thanks for the $200 bill, casa.

I am very disappointed with the level of service that I had received throughout multiple visits while both under my house warranty and after it had expired. Ever since I moved into my new home, I have had to call out a service technician each summer for a mechanical failure. With this being the third year I had the same mechanical trouble with my AC not working fully. Either it would only work upstairs, downstairs or not at all. Each time the technician would come out they would spend less than an hour turning things off and back on in sense resetting the system. This treated the symptoms only and not the actual cause.

Fast forward to this this summer, same issue with my AC not working. I called to have a tech come out to look at the device. He spent about a half hour at my place for which I was charged $105. The only thing he did was power the unit off and back on and replace the thermostat. This was on a Thursday. I find out later on that Saturday the AC goes off entirely.

I had made an attempt to get a tech out again but schedules conflicted, and I missed the window. I called a different repair technician who was able to come out the same day. The individual spent well over four hours working on my unit to make sure it would start to work. He even ended up having to call in his boss to find out what was going on with the system.

As it turned out, multiple issues had occurred including lose wires, a broken board, and low on coolant. They explained to me to get everything up and running with replacements it would be around $1000. I was very upset to hear the number. In all the times I had someone come out to look at my equipment from Casca Mechanical, not one agent went the extra mile to find out what was really going on with my equipment. If they had, I can't help but think the repair bill would have been less or even none at all. It is very frustrating that I live in a brand new house with everything being just over three years old and already a major competent has broken down.

TL:DR
If your AC breaks down under warranty with Casa Mechanical, call a real technician to come out and look it over. Better to pay a service call around $89 than to have to fork over a $1000 due shoddy work.

I am not impressed at all. We had a time window for a repair of 8am-noon; it is now 5:40pm and we are still waiting!!! Unfortunately, this is a home warranty repair for our new home, so I guess that means we aren't as important as the customers who pay?? They called at one point and said they'd be here in 20 minutes, that was at 1-something and then this last time to say by 5:30pm.
The office is now closed, so I can't even get an update. I will certainly not be using this company for any repairs we need in the future. I'm also reaching out to our builder to let them know about our experience. Update: the guy who finally got here didn't have the part and we had to tell him what he was supposed to fix!!! I mean clearly someone in the office needs to learn how to schedule and how to make sure the guys coming out have everything they need!!

Casa Mechanical installed a brand new Carrier Infinity system in our remodeled home in 2013. Since that point, we have had annual, ongoing issues with board failure and communication to the thermostat. In each of those instances, I have had to pay outside HVAC companies to service what originally should have been covered under warranty because Casa Mechanical does not provide same day or next day service like EVERY OTHER COMPANY IN TOWN. They are consistently 1-2 weeks out for maintenance/service scheduling which is simply unacceptable in the Texas Heat. Had I known how impossible they are to work with I would never have used them for the initial HVAC installation.

This was a smooth and pain free process. Thanyou to Evan , Gus and his Team, and Casa for a job well done!
How things went- Refered to Casa by a colleague as he had a pleasant experience also.
Called Evan in the AM regarding my AC problem; he came by that same afternoon.
I had already received a couple of quotes from other companies, so by now I am up to speed on what to expect.
Evan gave me his estimate and it blew the others away.
I have been given discounts and rebates from the other companies quotes but none could touch Casa's. Seriously, it was so much better for the same exact parts. I was skeptical, at first.
Anyways, We scheduled it and Gus and his team came out to do the job. They were courteous and mindful to our belongings; putting down sheets and plastic to protect our floor and furniture as needed.
They were efficient as each took care of their individual parts of the install and came together for the joint work.
They finished in the time Evan estimated and made sure we knew how to use the new equipment.
They also showed us the old stuff that was being removed.
Ultimately, the new AC is working flawlessly and I love the new wi-fi thermostats.
I will update in about 6 months on whether everything is still going amoothly.
Thanks again Casa for a great job

A technician came out checked out system, explained everything to my wife that he had checked and they left extra filters for our inconvenience. I feel that they are trying to do everything they can, to make things right.
