All Temp first came to our house in May of 2024 for trouble with an existing system installed by…read moreanother contractor in 2015 and moved by yet a different contractor in 2020. A few technicians came to the house over a few months and with the unit under warranty they had to order a blower motor for the unit that took a bit to come in from the manufacturer. The last tech that came out was Glenn and he worked to get a few door panels that were damaged by the previous contractor in 2020 replaced under warranty. I appreciated the level of service back in 2024 and when the system recently had an issue with the compressor, I contacted All Temp for an emergency call and then decided to go with a new system. Glenn still works at the company, and I spoke briefly with him over the phone and Dylan came out to do a survey of the house and gave me three recommendations on replacement units. I would also recommend an Energize Delaware assessment because there are rebates to be taken advantage of for insulation, crawl space encapsulation, and an energy efficient system. The lower priced model didn't fall into the rebate and so of the remaining two we choose the American Standard Platinum 20 SEER2 variable speed model paired with Platinum variable speed air handler. They were able to get the installation on the schedule quickly (for summer) and Dylan takes the extra step of taking the rebate off the price and putting it in through Energize Delaware. Tony, Matthew, and Ken came out, were very professional and did the install in half a day; great teamwork. We also went with a thermostat that connects to our Wi-Fi that allows All Temp the ability to view remotely if we have any issue with the system. Shane was scheduled just over two weeks later and did a quality assurance inspection of the work. The truth is that Glenn sold me a system in 2024 with his level of service and follow-through. This company is worth a look if you need work done on your heating and air conditioning system.

Then they send me a bill for another visit for $579 and a proposed replacement of the condenser coil for over $2,000. Unnecessary! Another company repaired a small leak near copper ending for under $100. Looks like Sherman Tech had no idea what to do. Of course, never communicated with the owner. They just sending us bills! We terminated the contract, and hope no one gets stuck with this group of expensive and unreliable service. Good luck!

This process is very safe once the polymer cures, but you do not want it to dry in your lungs which happened to me because they did not plug the registers properly. It has been a year and I still have breathing problems and use inhalers regularly. In my opinion Lawson did not train their workers properly to work on HVAC systems . Another big problem was that the one air suction filter box they used was too small for my 2800 ft house. In conclusion i made a HUGE mistake in hiring them ....

I asked the office what was covered for free per the website, and this was the response: "To clarify, while we do offer free estimates, the $179.00 service fee was disclosed during our initial phone conversation. You had the option to decline the service at that time if you did not agree to the charge. Additionally, had our technician identified any further issues with your system during the visit, a free estimate for that specific repair work would have been provided then." I must have misunderstood during the original call, but beware that free isn't free. Also, the tech called at 915, told me he would arrive between 1015 and 1030 and got there around 1115, outside of my 9-11 service window.
