Reviews

What customers say

Customers describe prompt service, with two reporting same-day visits; one also appreciated Josh's clear explanation of options. A homeowner reports more consistent temperatures after replacing an older HVAC system with a cold-climate heat pump and gas-backup furnace. One reviewer alleges a dispute over an increased quote and says a down payment was not returned.

This company is accused of entering a contract, not providing necessary information, increasing the quoted price, and when the customer disagreed with the increase, Temperature Doctors refused to return the customer's $250k down payment. It is case number 2024-LA-0000074 filed in the 17th Judicial Circuit Court of Winnebago County. There is another case of eviction also filed in 2024 with the same court that alleges the company damaged and/or stole items attached to the building when they vacated. Also note that the owners and workers are of a certain religious organization which questions whether the excellent reviews are from members of that organization, as compared with reviews elsewhere and word-of-mouth reports. Please note that the reviews here name the same individuals, which indicates this is not a company with sufficient technicians to be on more than one work location at a time. Update due to reply. Consumers have a right to know the public record. Self-serving proclamations taint credibility. It sounds defensive, especially when Temp Doctors say they didn't pay the rent for almost a year because they didn't know where to send the check. (That was TD's defense.) That doesn't sound professional.

Gary Hacker

Temperature Doctors replaced my 35+ year old HVAC with a new cold climate heat pump with gas back up furnace. The new system is performing great. Temperature control in my tri-level is much more consistent and I look forward to the energy savings the heat pump will bring this winter. Josh was very knowledgeable and helped me design the right system for my home. The installation team was very professional and the job was completed in a little over a day.

My elderly mothers AC went out Randy from Temperature DR came out the same day. The AC unit was old and the cost to repair did not add up. Joshua came out the same day and gave us a good price and Randy installed it the next day. This was great service and highly recommend Temperature Dr

Amazing team. They came out the same day we called. They were efficient and very friendly. We were given several options and Josh took the time to explain each option to us, in a way we understood. I appreciate the hard work and dedication to making sure my family and I had air conditioning that works. Thank you temperature doctors!!!
