Very frustrating experience with Allen. I was promised a 16 SEER, 2-stage HVAC system with a WiFi thermostat, but they installed a 13 SEER single-stage unit and a basic thermostat. I only caught the mistake because I checked the equipment myself. They returned to replace the equipment but left without getting the system working—while still cashing my check for completed work. I then had to call and insist they send someone back. They’ve also repeatedly promised to schedule a duct cleaning but haven’t followed through. I’m still without a working HVAC system and highly regret choosing Allen.
Jon Harris gave me an estimate on the cost of replacing a mixer valve. He explained thoroughly the work that needed to be done and gave me a reasonable estimate. He was friendly,easy to talk to, and knowledgeable.
Zack Johnston was an outstanding representative of the company. Goy our AC unit going again. Prompt, professional, personable, hard working in every way. Will request him again!!!
DO NOT GIVE THEM YOUR BUSINESS. Insane markups for repairs and materials. I have a heat pump system that Now Heating installed merely 3 years ago, and Allen Service has since absorbed that company. The heat pump stopped working, and the service technician that Allen sent out said, "oh wow, you have a refrigerant leak and it looks like the welding on this install was really poor, that is probably contributing to the issue. Since this is an install issue, we should be able to cover most of it." I have since gone back and forth with the company, and finally got an estimate for a ~$7000 repair (despite them acknowledging it was an install issue, it doesn't seem to matter). The system itself cost $11k new, so now they're essentially asking me to buy a whole new system. To add insult to injury, they said the refrigerant alone would cost $2,700 for 8 pounds, which is a 300-1800% markup for what it should cost (based on commercial vs wholesale price). Absolutely insane business practices, do not use this shady, shady company
Allen services used to be great, but lately they have been very disappointing. We have a membership to have scheduled maintenance with Allen services, and we scheduled a plumbing inspection several months in advance. The day of the inspection, I called for a time window of when the technician would be arriving, and they canceled the service and wanted to push the appointment out by four months for absolutely no reason. If we had known this was going to be the case, we would have used a different company. I would not recommend using Allen services to anybody that I know. Please save yourself the trouble and call anybody else.
