Receptionists were friendly, responsive, and knowledgeable. Was able to get a weekend diagnostic and a followup repair appointment for Monday from a last-minute call. The two technicians were thorough and courteous (wore masks, and boots when inside). Jason was able to find a leak in our line set that two previous companies completely missed. After repairing the leak and recharging our heat and A/C were back to working. No BS. Prices seemed fair for the work they performed.

Excellent service. The technician was on time and very thorough in explaining the issues that were going on with my air conditioner. His honesty and professionalism were very much appreciated. I’m relatively new to using Alexander, but I’m very much impressed so far. I would definitely recommend them to anyone needing service.

When our AC was out, Alexander worked us into the schedule same day (called at 8am), and had the system fixed 3 business days later, which was a lot faster than I was anticipating since they had to order the part. They showed up on time for both appointments (a rarity in the service world). Highly recommend.

They replaced an expansion tank and did a quick, prompt job. He was on time, professional with mask and booties. Couldn't have been nicer and it was all repaired very very quickly. I was impressed as usual as I use them all the time!

Derrick was friendly, quick, and on time. Fixed my heating and even took the extra steps to be a bit quieter so my one year old could nap. A+ quality service, and 100% will be using again.

This company is great! We recently had to replace our HVAC and they were able to get a new unit in promptly. They show up on time, communicate with you, and are professional.
