"While having my siding removed and replaced, decided to insulate the exterior walls. They coordinated with the painter and checked the weather for when the project could be done. Also, the estimate was given several months in advance and was still honored once the project got going. They needed to come out twice to install the insulation because the siding took time to come off the house, but they were more than willing to work with the painter's schedule to make sure things got done in a timely fashion. Friendly folks who take time to answer questions and did excellent work getting the house insulated and now operating efficiently."

"Cody did the install. He did a great job"

"I had a hot water heater replaced a few years ago by Mission and had a crucial part stop working. While the part was still under warranty, I paid for a service fee to have it replaced at a fair cost (just labor, the part was under warranty). Unfortunately, the replacement part failed in a short time. Long story short, they came back out and spent time on two different days correcting the problem and replacing the part. It really was just one of those odd-ball everything goes wrong kind of malfunction, although it was no fault of the company. In the end, Mission Plumbing sent me an invoice with a zero balance. It was quite the headache for them, but they honored the warranty to the max even though it cost several man-hours. I will definitely use them for future needs."

"He came in and looked at the air conditioner and the furnace and pulled out the book and calculator. He suggested me all I wanted and he gave me the best quote for it. I am happy with them. They were prompt and the guy was on time for his call. He got down to work and didn’t mess around. He didn’t try to oversell me."

"Prior to calling Bob, we had several guys come in to give us estimates. Bob's estimate was by far the best and the work he did was top quality. He and his guys moved my existing furnace to a new location int he basement and installed a new AC. They also moved the hot water heater. I am very pleased with his service. They were prefessional and respectful. Bob is a straight shooter. Absolutely no BS! I will be using him for ALL of my future HVAC needs. I HIGHLY recommend you call him and have him come give you an estimate if you need service, repair or replacement.

"Fantastic company!!! Mammoth removed my conventional HVAC and all ductwork while upgrading my home to an energy efficient split system.... which is amazing! My entire house is comfortable, the system is great and our overall energy bills have dropped! The Mammoth team were on top of their game and I couldn’t be happier with their service."

"Prompt and very professional. Being in a newly purchased home, we were unsure of the condition of the furnace, they were very thorough with their inspection and answered any questions we had. They were great!
