Review: I have been using Alltemp for the passed couple of years. They always do a good job maintaining my furnace. I also appreciate that they are easy to communicate with and will give you an approximate ETA the day of service within a couple of hours. Today, Noe gave me a call about an hour before he arrived, he seemed to do a fine job, and he was professional and friendly.

Review: We have been very happy with the services provided by All Temp Heating & Air Conditioning since we became customers 2 years ago. Its technicians – Edwin, Larry, and Nikola – were professional, knowledgeable, and courteous. They took the time to answer our questions, and address any concerns we had about the work being performed. They were honest in their assessments, and did not recommend unnecessary services, further solidifying the company’s reputation for ethical business practices and impeccable customer service.

Review: All Temp is a top-tier company that has serviced our home for many years, and among their team, Ed Baharopoulos stands out as truly exceptional. He completed our spring HVAC servicing today and is, without question, the best technician we’ve had—extremely knowledgeable, meticulous, and dedicated. Ed goes the extra mile to ensure the system is fully prepared for reliable performance across all four seasons. He works efficiently, evaluates every component thoroughly, and takes the time to clean and optimize the entire setup. I give Ed my highest recommendation—he is in a class of his own among technicians we’ve encountered from any company.

Review: Mike clark provided the proposal and provided a few options to meet our needs and budget. He was knowledgeable and answered all my questions. Marlon and Luis were great installers and walked me through the furnace and AC units and functions. They recommended another return in our basement which they were able to install and still meet the timeline. Overall, it was a smooth process and would recommend All Temp!
