Based on the ac system alone, maybe 2-3 stars. It cools, sort of. For $20k I'd say that's the bare minimum. However, they are in no way qualified to install anything with ducting.

They miscalculated and used the wrong size (bigger isn't always better when it comes to HVAC) duct for our upstairs. When they realized the system was over cooling the first 2 legs of duct work, undercooling the second 2, and providing ZERO cooling to the third they had to come, rip it all out and reinstall, but left a mess and some massively oversized holes. 2 months in and the system is providing ""air"" to the house, but not really in any way controlling the temps (program 70, and get anywhere from 64 - 76, our old ""dumb"" thermostat was better).

3 more service visits and 6 months later they finally got a Daikin (manufacturer) rep onsite who said they did the install wrong - and it would be 2 more months before a Daikin engineer could come out and fix it because ALL THE PROGRAMMING IN THE THERMOSTAT IS LOCKED DOWN AND PROPRIETARY, AND DAIKIN DOES NOT SHARE WITH THEIR INSTALLERS HOW TO MAKE ANY BUT THE MOST BASIC MODIFICATIONS.

11 months later Daikin had an engineer come out with Wally's A-team and another contractor from a completely different outfit, who seemed at least a little informed with how Daikin systems should be installed (""Randall"" from TCC), and the 3-some managed to get acceptable performance (program 70, get 68-72). Do with this information what you will, you've been warned. And

FYI, the basic wall-mount mini-splits that they installed on our other floor - I installed 2 more myself for 1/5 their cost, and I honestly can't be any worse than them. At least I know if I installed it I can be there to trouble shoot in hours, not weeks. But hey, now I can add ""HVAC install"" to my list of skills.

Walley's came up in a search as one of the top plumbers in the area. Before calling I checked to see if they serviced Chester. Called to make an appointment for an estimate which I was told they would call back. They called back quickly, telling me that this company doesn't serve Chester. My response was to let them know that Chester is on the list on their website and that that I was unhappy with their false advertising. Disappointing.

i wish i could provide negative stars!! after waiting all winter to have our brand new air conditioner that was a nightmare to install from this company, they came out, turn it on, and blew out our entire hvac system. the heat, which was working yesterday, is now also gone!!!!

stay away from this company at all costs! they are beyond incompetent, and now we are out over $8500 and have no air conditioning or heat.

i will be contacting the bbb, and likely need to hire an attorney to get this resolved.

do not do business with walley's!!!

Called Wally in for a problem with our commercial boiler; one that HE installed 3 years ago. Himself and 2 others were unable to diagnose a simple check valve that had fallen off an expansion/blowdown tank! Had to hire Denron Hall to fix it properly. Didn't stop Wally from charging me though! and telling us we are blowing down the boiler incorrectly! OMG Wally, just take my money, buy a tank of gas for the boat and float off!
Terrible, untrained service!

My circulator pump went for the main zone of my house. I put in a request for service and an estimate on their website, and was promptly called the next day at 8:45 AM. I received a reasonable quote within the hour and they had a service technician at my house by 3 PM that same day. Service technician was friendly, and got the work done expeditiously. I am so sick and tired of getting taken by the big name plumbing outfits that advertise heavy on TV. Walleys will definitely get all my plumbing business going forward. Highly recommended.

Right on time for appointment! Polite and pleasant serviceman. Fixed problem quickly! I will be calling these guys instead of the ""big box"" companies.

We had our central air conditioner replaced in June by very competent plumbers. We had our water heater replaced yesterday by another wonderful plumber named Rick( short for Richard) who was very caring about apparently a sediment problem that came up after the new water heater was installed and he came back and made sure everything was running perfectly. Great customer service! Michelle in the office is so pleasant and kind to deal with too.

So happy we chose Wallley's for our furnace cleaning.
Great communication and response.
Courteous and friendly workers with a special shout out to our tech Ed!

We spent 4+ months deciding on who to replace our furnace, central ac, and tankless water heater. Walley's proposal was by far the most thorough. Their price was among the lowest. Their 5 year warranty on labor stood out vs 1 year for everyone else. They were not a high pressure sales-oriented team (particularly like 1 large company with lots of advertising). And above all, the quality of their communication and installation was first rate.

Another 5 star visit and interaction. Time and again, Walley's proves to be the best in town. Courteous staff, always tries to find a convenient time for you, no matter how busy they are. They adapt to circumstances and roll easy. Technicians are personable, on-time, fun to work with and quick to resolve or complete the work with a great deal of knowledge. It's real easy to do business with them. Prices are fair and reasonable, process is simple and responsiveness is great.
