In a 2025 Google review, the reviewer said they swung by the same day to look at a broken AC unit, fixed it in about an hour and gave a great fair price. A 2025 Thumbtack reviewer said Dionair installed two Nest thermostats and did a great job; that 2025 reviewer needed the project done on a tight timeframe, said Joe went out of his way to make sure it was done, and said Tim came out on a weekend to complete the job. Another 2025 Thumbtack reviewer said Joe texted before he arrived, arrived when he said he would, and got right to work to analyze and solve the problem. In a 2026 Thumbtack review, the reviewer said Joe did a wonderful job explaining their options and was super efficient in completing the work.
