Best Cooling/Heating in Phoenix AZ

Dominic was awesome very professional replacing a water heater that died clean install.

I called a contractors directory for a water heater issue and was given Hays and so happy I was!
Justin arrived and not only helped with my water heater issue but advised me and helped me with my air conditioner and heater too!
Great service ??

Justin is a great representative for this company and the company should be happy to have him. He is very professional and truly understands air conditioning. Every time he comes by I learn something new.

I really enjoy using Hobaica for all my household repairs and needs. They are quick, efficient and friendly. Travis Vonau was my service tech today and he did a phenomenal job. He was on time, did a thorough walk through and explained everything he found and could do to fix the issues I was having. Thanks Travis Vonau and Hobaica for providing excellent service!

Great business!! David was on-time, professional and took the time to find the problem and fix it as opposed to trying to sell me an A/C as most other companies do. Very happy. Will refer you if anyone needs A/C heating help.

I was so impressed with Desert Diamond! Their technician Isaac was extremely helpful and knowledgeable and answered all of my questions. They performed their tuneup maintenance quickly and efficiently. Isaac took the extra time to answer my specific questions about our cooling and heating system and I feel much more informed about any next steps I need to take. And those next steps will absolutely be with Desert Diamond!

I love this company and have referred them countless times! They are honest, their staff is courteous and knowledgeable, and they are great service providers. Highly recommend!

I called the company and spoke with Jesus. Regarding my central air wasn't working & he came 30mins later to fix my air system. I really appreciate the fast service now I have air something you need living here in AZ. Thanks again Jesus!!!

Dylon was thorough and informative. He answered all of my questions and flushed my water heater competently.

Q provided amazing service. We found a solution that met my needs and he helped keep my air systems running at peak performance.

They use the technology available to contact you alerting to appointments and are typically here on time.

High quality and on-time performance, Excellent warranty, Honest and Trustworthy, Fairly priced

Best service we have received in a long time! This company is on time, reliable, friendly and most of all clean! I wouldn’t hesitate to use them again or recommend them!!

Thank you!

I have used several plumbers over the years and this time I tried Klein Heating and cooling. They were professional and courteous, and very safe by wearing masks and cleaning the work areas afterwards. Their office staff was knowledgeable and friendly. They were clear about the issue and what the costs would be. They made sure it was fixed right and didn't cut corners. I would use again and definitely recommend.

Honesty is what I was looking for. I had 4 companies come out before Sun Devil. Each experience with the “other guys” left me feeling unheard and like my questions or input annoyed them. Gerardo is The Man!!! He came out next day, we walked through every room and talked about the little details. He was straight up with me and honestly out did these “other guys” in all facets. Customer service, knowledge, speedy service, and most of all price. After we agreed on everything I could call or text with any questions and he was right there to let me know what when and where.
I can’t say it enough, these guys are GREAT! I’ve recommended them to anyone I run into that needs HVAC services big or small.

I have relied on Four Seasons to handle all of my HVAC needs, since basically the founding of the company. From complete new home system design & install to emergency repairs they've always been there for me, my friends, and relatives.Their company has grown, but the level of customer service has never wavered! It truly is like calling an old friend when I need something done. Thank you, Kevin and Jess for taking the sweat out of a broken AC unit!

Miles H. is very knowledgeable and thorough in identifying and sourcing problems/issues to properly resolve them. He freely communicated with me on any aspect of the HVAC system I had questions about. Miles is a pleasant, solution-driven and customer-oriented technician, giving me great confidence in him and SG Mechanical.

Called with a hose bib leak - had to turn water off. They came out and fixed in less than 2 hours, amazing! I use them for my air con service and this was the 1st time for plumbing!

This company and their employees are awesome.

Air out and fixed in less than 12 hrs! They are fast and amazing! And very reasonably priced!

These guys were great. They knew what they were doing and did everything as planned and at the agreed price. They even fixed some minor settings in the thermostat that were set at default by accident. No extra charge.
