I requested a new unit from Herman Allen in September 2023. There was not enough airflow flow for the system to work. Then they had to modify the carrier unit and add another filter because the factory installed air conditioning unit was incorrectly engineered. I now have 2 filters, with two different sizes. Then after the labor warranty ran out, The mother board and the pressure switch were faulty. Carrier has a parts only warranty, and they have to take the compressor apart in order to place the valve. My costs to fix this are $149 for the service call, $500 for the board and $1200 for the pressure valve. Herman Allen stated that after I pay them the system may not work. They also believe the motherboard and valves were placed incorrectly from the Carrier factory overseas. i would not recommend Carrier nor Herman Allen

Herman Allen keep sending me a invoice for payment. Two months in a row. I checked with my credit card company, IT WAS PAID IN FULL. It states in red "" please pay in full to avoid further collection activity "". I call them they said it is showing paid in full on their end. WHY THE COLLECTION LETTER?

Ripped off. I was hopeful of having a good experience, since a friend referred me to this company, but that didn't happen. My A/C fan was constantly running, but not cooling. They came out and said it needed a capacitor, and that it would be $405. I agreed, thinking it was an expensive part and he needed a good amount of time to do the job. It took 45 minutes tops (he also cleaned the screen on the sides and checked the filter ""for free"".). He didn't leave me with a receipt, so I asked for one, and he emailed it right away. It was NOT itemized, and so there was no way to know how much they charged/hr., or how much the part was. I looked up the part online, and guess what...about $10. So BUYER BEWARE.
When I called the office for information about hourly costs and the part cost, she said what another reviewer reported upon his call: that there is a flat fee, etc. Oh, and there's a $15 charge for their gas, since prices are so high, and to keep their ""fleet mobile and ready to serve.""
The only positive part is that my AC is working, and the technician was very nice, but I WILL NOT BE USING THIS COMPANY AGAIN.

I was very empress with this company. The salesman, Keith, was so thorough and patient, explaining three different plans. He sent an e mail with all three estimates within an hour. I had my new gas furnace and electric air conditioner installed within a week. The two installers where very friendly and knowledgeable. They where clean and explained everything to me. I will definitely will be recommending Herman Allen to my neighbors.

I've called them out repeatedly for the last 2 years to fix our warehouse heaters.
All they do is keep coming out and replace parts that don't fix the problems.
Each tech they send out tells me it's a different issue and never get the units working, and I've had to call after being billed to tell them they're still not working. Also, they had to come out twice to fix our AC. One tech changes some parts, second tech comes out and says it's the transformer. Their ""we're not the big guy commercial"" - well they charge like one and can't troubleshoot the problems that result in working units. Maybe have to call one of the ""big guys"" at this point.

Purchased a brand new heat pump 5 years ago from another company, never had any issues. Paid $249 for the maintenance plus plan with a Tech coming out Thursday for a tune up. Within 48 hours my entire system crashed. Called their office and a Tech came out and said compressor and fan were overheated, but didn't know why and to leave it off until the next day, then gave me an approx $350 bill for him to come out. Capital City Cooling came out the following day and saw two wires had been switched on my capacitor, switched them back, and my system was back to normal. Credit to HA's manager, he apologized and is providing total amount I spent back to me which is why I bumped my review from 1 to 3.

This company was lovely to work with. Their communication not only with scheduling and reminders, but also with Covid-19 protocols was very thorough and helpful. Jon Armstrong worked with us and he was fantastic! He was so polite and respectful (and very sweet to our rambunctious dog((thank you for not being annoyed))) I will be recommending this company to all who need any home repairs in the future!

I had a new hot water heater installed by Jimmy Davis and his team. They did an outstanding job as the hot water heater was installed to perfection. All members of the team were very professional, extremely knowledgeable and customer friendly. I highly recommend Herman Allen Plumbing, Heating & Cooling.

Would give NO stars if that was possible. Here to do a very small job (disconnect under sink plumbing and take out disposal and disconnect gas cook top and cap it off so that granite could go in.) When I called I was told cost would be $125 or less. Got a bill for $160! This after they took the disposal with them and it had to be brought back AND they could not come back to reinstall plumbing for 5 days, leaving me without a kitchen to use during that time. I called in another plumber and for less than 1/2 that price he came and in 15 min reinstalled it all. I called to say bring back the disposal. My guess - they would have kept it and charged me the $160. SHAME on them. BTW it took them 15 min to do the job and they were 3 hours late.

Would highly Not recommend this company. Called with a basic plumbing issue. The quote was 2x more than anyone else. The guys they sent out were pretty rough and then asked for a mandatory payment ""allegedly"" which had never been disclosed up to that point. Needless to say I went with another plumber. When I called about the bill, the guy (no joke) hung up on me.
