Allegiance delivers. Had a humidifier problem and Riley fixed it promptly. He's super knowledgeable and methodical. The whole team is top-notch, making Allegiance my go-to for HVAC services.

The installers arrived at 8am and finished by 4:30pm, completing a duct cleaning, A/C installation, and furnace setup. They met with Manager Brian on Monday and completed the work on Friday. The sales team were extremely helpful and knowledgeable, making the financing process seamless. The system now works flawlessly.

A huge thank you to Allegiance for delivering top-notch service when our AC started leaking water over the weekend. On Monday morning, their team provided expert advice and installed a brand new unit on the same day.

They were highly knowledgeable, friendly, and kept us informed every step of the way. Their professionalism made a big difference - I'm glad we chose them for our installation and I'll definitely be using them again for future projects and maintenance.

A late review, sorry about that.

Riley and John were a fantastic team. Their prompt arrival set the tone for a great experience. The duct cleaning was thorough, and they left everything tidy. Next, they tackled replacing my furnace. Throughout the day, despite my dog's poor health, Riley and John showed remarkable kindness, carrying her to the car when I needed to take her to the vet and then again when I returned.

Their professionalism was impressive, and their compassion towards me and my ailing pet was truly appreciated. The rest of the team that joined in to complete the installation were also a welcome help.

Overall, this company delivered exceptional service, and I have no hesitation recommending them for furnace and air conditioning work.

We were impressed with Allegiance's performance from start to finish. Their technicians are respectful, on time, and demonstrate expertise in their trade.

This company's technicians arrived on time, dressed professionally, and showed good manners. The duct cleaning and dryer vent services were done well, and the installation of my new furnace and AC was completed efficiently. They clearly take pride in their work. Natalie was very helpful with communication throughout the process. It's clear that the team enjoys their job and has a strong working relationship - this family-run business is definitely recommended for its quality service and friendly staff.

The service tech was knowledgeable and did a good job. Unfortunately, they didn't follow through on the agreed price. I chose to have my humidifier checked for $99 instead of $125 because it would give me the same level of attention at a lower cost. However, I ended up being charged the more expensive option. The billing process was frustrating, and when I brought it up, they became argumentative about crediting me. It's disappointing to be overcharged by such a small amount, especially when it was clearly communicated upfront.

Climate Masters has saved our family twice from a stuffy home - thanks to their swift response, flexible scheduling, and outstanding service. Despite having an antiquated furnace over 20 years old, they didn't recommend replacing it. I'm confident in knowing who to call next time.

Kimie kept me updated on the scheduled visit. The technician, Shawn, seemed knowledgeable about the equipment despite being new to the property. He completed the necessary inspection and repair promptly. The work was done efficiently and at a price I was comfortable with. Overall, a satisfactory experience.
