In the end the new system needed to be replaced - so Fiscor did just that. They installed a brand new system and sent nearly every manager/specialist on their team to triple check everything before they left. They made a bad situation right and I truly feel like Fiscor is my partner and I'm happy that they will be the ones to maintain my new system throughout its life. Thank you Casey and Jason!!!!

I cannot recommend Fiscor Plumbing and Air due to a complete lack of billing transparency. I hired…read morethem on August 3, 2026 for a repair on my AC Unit. While they completed the work and received immediate payment, they have repeatedly refused to provide me with a proper, itemized invoice. My current bill only shows a single lump sum. It completely lacks a breakdown of labor costs, individual part numbers, or the specific pricing for the components used. I have called the office 3 times requesting a standard itemized receipt for my records, but they continue to give me evasive answers. As a customer, I have a right to know exactly what parts were installed and what I am paying for. Hiding the breakdown makes it impossible to verify if the pricing is fair or if the correct parts were actually used. Avoid this company if you value honest, transparent business practices.

However, they tried to take advantage of me saying my 12 year old unit needed to be replaced & new units are 3x as expensive. If I made a bad decision & did just the repair it would be $3k. All that didn't see right so I researched for someone else. Red Rock has excellent reviews so I called & they came out the next day. Not only did Chad say I didn't need a new unit, which would be much less than what the big company quoted, my repair was simple and half the price quoted. I didn't hesitate and said Red Rock is my new a/c company! The only delay was ordering the part directly from Trane but it was only a couple of days, and my a/c was working so not an issue at all. What a relief to have an honest, knowledgeable, and friendly expert in a/c, which is crucial in AZ. I will be signing up for their yearly maintenance plan next year! Thank you!

I called Connolly to repair my 7 1/2-year-old heat pump system after it stopped working. The…read moretechnician was at my home for less than 10 minutes before telling me that the system was "contaminated," needed to be flushed, and that I should replace the entire unit. The estimate for a new system was nearly $16,000. I felt that recommendation was excessive, so I decided to get a second opinion. The second company diagnosed the problem as a faulty valve inside the condenser unit. The repair cost was approximately $1,100, and my system is now working properly. Based on my experience, I strongly recommend getting a second opinion before approving any major repair or replacement recommended by Connolly. I would not use their services again.

This story is hard to believe. A few weeks ago, I couldn't find the name of Connolly electric…read morebecause I'm older now, and a certain company came up, and all I wanted was to have insulation installed on my outer AC pipes to the outside of my house. I couldn't find the proper insulation, so I hired ****** to do the job. He did a great job, however, he comes in the house to inspect my unit, and notices that there was a rust stain at the bottom of my HVAC system. He proceeds to tell me that it may not have much life left, and he also noticed rust on the fan outside. Obviously, water wasn't draining correctly, however, my system worked perfectly, giving me great heat and great air conditioning. He said that I needed a new unit, and that prices were going up practically every day. I told him that I would wait until it broke, but he was insistent. Even my wife told him that we couldn't afford it. I'm really hard to sell, as I was a top salesman in my company. Somehow, he finagled his way out of my wallet. He quoted me $14,000, and I went for it for some stupid reason. The following week, they come to my house to install the unit which is almost twice as large as the one I had. I told him I didn't think I needed such a large unit, and from what I remember, he told me I did because it was very hot here. Anyway, three guys came to install it, and first of all, I don't know whether it's their fault on or not, but a downdraft unit came instead of an updraft one. The guys had to wait many hours for another one to be sent. Eventually, it came, however, the unit was so large that the tray that holds the filter underneath wouldn't fit, as the guy forgot to measure correctly. They actually installed it without a filter underneath so we'd have air conditioning. Fortunately, the filter fit in my intake in my house so we wouldn't get dust through the unit. When the machine turned off, the vents banged as there was too much pressure for my little house. Also, they did not change to a higher amp fuse, which should have been 60 amp instead of 30. They put in a 5-ton unit, and I had a 2-1/2 ton unit prior. I told Connolly that our bedroom in the front of the house faces the Sun, and it was hard to cool and heat only that room, so they put a 3-ton unit in. Here's the deal, instead of paying $14,000, I paid $8,200, almost HALF the price from Connolly. My builder will only use these guys, and since my guy is honest, I will agree. Damn, I should have called him first! Oh, by the way, my house is only 7-1/2 years old and 1,500 s.f. large. I would have reported the other guys to the Arizona Contractor office, but they gave me my 7,000.00 deposit back. Just be careful who you deal with, and thanks, Steve, for a wonderful and clean install, as well as Trevor and Todd, who I assume are either owners or managers.
