My HVAC repair was handled quickly and professionally.

They replaced our unit last year. Just had the first check-up for the heating and cooling system. Everything is perfect.

Our furnace wouldn't ignite during the coldest week of the year. Their furnace repair team diagnosed a faulty thermocouple and replaced it on the spot. We are so grateful for their speed and expertise.

The technician arrived exactly on time and fixed our refrigerant leak quickly. He even took the time to explain how to maintain our unit better. Truly professional and knowledgeable service. Five stars all around!

Amanda was awesome and helped detail items that can be addressed in the future (will definitely take that up). Super knowledgeable and explained in terms that were easy to grasp.
Overall an excellent experience and will be recommending Koala to friends and neighbors!

Kyle was fantastic to work with. Friendly, well spoken, concise, and very thorough, let me know exactly what the options were and what he recommended. Had everything done and all of my questions answered in an hour flat, even with needing to run out for supplies :)

I scheduled a yearly HVAC inspection accidentally, and I didn’t realize it until my techs arrived. Fortunately there was an affordable special for it, as well as for the plumbing inspection that I meant to get, so I went ahead and had them complete it anyway. Amanda and Isaiah were both so so friendly, knowledgeable, and thorough. I was very pleased with their findings, their work, and the information they provided. Thank you!

Amanda was awesome! She was very polite and professional. After her assessment, she sat with me and went over all my options with clarity and honesty. That was greatly appreciated! I have moved this project to the top of my list. Thanks for the great experience!!

Update - Response to the owner: No thanks. Please see Photos for the estimate that your company provided vs. the one we proceeded to work with.

Very disappointed with this company. They quoted me an outrageous price — nearly three times higher than other estimates — just to repair a sewer line. On top of that, even though they charge for their service, they never provided any proof of work or inspection. I would give zero stars if that were possible. Not recommended.

Entire team at Koala (Zach, Luis and Jose) did a great job. From explaining the recommended work needed to completing the new A/C installation. Highly recommend them.

Update on April 21st, 2025 — Still 5 stars! We called Koala Cooling the day after Easter weekend as the air stopped working right before the weekend. Jacob M. quickly came out same day of call and replaced the capacitor along with a few other things and thoroughly explained everything along the way in addition to taking photos. Very professional as always. We finally have air again, thank goodness!

On-time, friendly, and thorough heating system evaluation as part of Koala Club! Michael Corey, our technician did an inspection and provided a great summary afterwards, including pictures — showing actual read stats vs what the manufacturer has listed on their equipment to show everything was working appropriately. Thanks Michael and the Koala Cooling Company for great service. Glad to be a part of the Koala Club.

Just had my spring HVAC system checkup. Both Alex and Isaiah were fantastic. Both gentlemen were extremely knowledgeable and professional. Once again I am pleased to be a customer of Koala Cooling.

Kyle was a great tech. He was quick and concise when finding the issues and letting us know the repairs. Michelle who scheduled us was easy to work with and got a tech out the very next morning.

The first few times I used Koala I was extremely pleased. Enough so that I gave them a five star review. That changed today. I called them to address a backed up condensation line on one of my rental properties. I never received a price quote for the work prior to completion but knowing the work involved and how easily it can be addressed (It’s usually a 10-20 minute job) I was comfortable telling them to proceed. When they called me back an hour later with a $500 tab I was floored!! $500 to blow out a condensation line. For that price I could have easily done the work myself in half the time. I won’t be using these guys again. If you use them make sure you get a quote upfront. The technicians are responsive and pleasant but their pricing is criminal!!

Zak and his crew did a full HVAC system replacement including duct work etc. in less than one single day. The best customer service than all other companies. They even cleaned up afterwards much better than my wife could. 6 stars. Highly recommend.

Alex and crew did an awesome job. They were professional, communicated well from the beginning, and explained everything. They were fast and clean. 5 stars.

Martin and the Koala Cooling team are outstanding. We needed a new system installed quickly before leaving town and they were able to perform the install quickly and efficiently. Our system is running great and we couldn't recommend this company any higher than we do. They are amazing!

We also had Adrian out to help us with a clogged drain. He was precise and fast. Very thankful for his quality service.

Amanda & Isaiah were out to our house today and did a fantastic job. They were both very friendly, knowledgeable, and did a great job explaining the process and the HVAC system to me. We’ve used Koala in the past and will use them again because of the great service.

Amanda Nations from Koala cooling was fantastic. Very friendly, very knowledgeable and did a really thorough job. I was impressed at the lengths she went to in checking both my HVAC systems. The systems are really old and she had a a hard time accessing certain parts and spec sheets but she did not give up until the job was done. I'm super happy with the maintenance work she provided.
