Wonderful folks to work with

They haven't done work for me yet, but they will. I seen examples of their work, absolutely fantastic. Some of the examples they have are out of this world.

I had some gift items I needed laser engraved but in a tight time window. Kyle and company efficiently got these done for us quickly and the results are terrific. Excellent results & customer service. Will plan to use MADD engineering again.

The creators of very beautifully wired electrical cabinets. I've seen a lot of electrical cabinets and their wiring looks so nice with labels clearly marked on both ends. The staff is very nice and very professional.

After a chilly morning, I was relieved when the technician arrived promptly within an hour. They efficiently diagnosed and fixed the problem, leaving me with a warm and cozy home. Highly recommend their expertise!

The technician arrived promptly, expertly diagnosing and fixing our A/C issue within an hour. Highly recommend!

Incredibly thorough vent cleaning; my A/C feels brand new! Highly recommend.

The team transformed our home into a cool oasis in no time, finishing the installation just an hour after arriving. Their professionalism and attention to detail were truly impressive, making the whole process seamless.

Yesterday, the technician arrived right on time and spent about 45 minutes thoroughly checking our A/C system. His expertise was evident as he explained each step. Our unit now runs smoothly, and I feel confident about its performance this summer. Highly recommend!

We were very pleased with the work done installing our new furnace. They were on time and cleaned up after themselves. Well done.

From the beginning to the end, I had a great experience with Allegiance. Ben diagnosed the problem with our system quickly and efficiently. I never felt like I was being sold an option that wasn't necessary. Victor and Carson soon were out installing our new system. Even after dealing with a poor previous install, they stayed until after dark to finish the job and familiarize us with the new system. Allegiance has definitely earned a new customer after our experience.

The crew was very professional and exceptional! I would highly recommend Allegiance for any HVAC work you need!

Very professional kind and courteous, very helpful on explaining things to me just a all around great company to deal with. I would recommend them to anyone. That need the heating in air system

These guys are always friendly and knowledgeable. They have a great service to come out twice a year to check the system operation that is very cheap and help stay ahead of issues and give peace of mind. They do always go for an upsell to recommend things to improve your system but if they didn't, they wouldn't be doing their job which is respectable and understandable. In all I've been working with them for years and never had a single issue. They are prompt, polite, friendly, and professional.

We’re having an unusual problem with one unit, and the technician (Garrett) had a lot to figure out. Very friendly, professional, and explained everything as he went.

I am very happy with Allegiance Heating and Air. All of the techs are very polite and knowledgeable about my system. I would recommend this company to anyone needing a new HVAC system or repair, and they are very close to my home which is a plus for me!

Riley took the time to go over the thermostat with me to understand the programming . Assured us all was good with the new furnace .

The first company I called spent 2 hours diagnosing my issue and quoted me $1500 to replace the compressor, which was near the end of a 10-year warranty, with a 1- month warranty on the work. They "strongly recommeded" that I replace the entire outside unit for $6000. I called Allegiance because they offered a free 2nd opinion. They had a technician at my home within 3 hours. Gilbert determined in about 15 minutes that the compressor was low on refrigerant and going out. In another 30 minutes he had it working well enough to keep my house COLD until the parts arrived. He was amazing and explained everything as he was doing it. Mind you, there was no charge for this visit. Allegiance quoted me $1547,after a veterans discount, with a 2-year warranty on the refrigerant and workmanship. This also included a new contactor, filter/dryer, expansion valve, and schrader valves. Jacob arrived a few days later with the parts and had everything done within 3 hours. He also leveled up the outside unit better which was badly needed. He was also amazing. Both technicians were extremely knowledgeable, friendly, respectful, and explained everything in great detail. The office staff were equally amazing responding to my questions almost immediately, after hours, via text message. They offered a maintenance plan for $17/month that includes 2 bi-annual visits with too many ammenities to list here. I cannot say enough good things about my experience with Allegiance and wish I could give 10-stars.

Allegiance was able to send a technician the same day we called, and Jacob did a fantastic job getting our unit back up and running. He was on time, very professional, and easy to work with. He will definitely be my go-to for all future maintenance and repairs. Highly recommended!

Technician was quick to respond and completed the job in a timely manner. Resolved ac issue rather than saying we needed an entirely new unit. Friendly and communicated well.
