Great Installation Crew from Haaks

The AC installation/Electrical crew from Haaks installed a new mini-split air conditioning system in my home. The guys were great and did a class act installation job for me, very happy. Early to tell how the AC will cool, but the heat works great. The team was fantastic to work with and answered all and any question that I had on the system. I could not be happier for the nice installation job performed. Thank you Haaks Team, I look forward to a nice cool home this summer. Dave & Lynn McCoy

Poor communication skills

I'm sure the work that was done was performed very well. However, he did not communicate well from the time he stepped in the house until when the work was complete. Also, I had to leave work early since he was running 45 minutes ahead of schedule.

Quick dependable service

Woke up to no heat. Black Haak responded and arrived within 45 minutes. Evan quickly determined the problem. Luckily we were under warranty and the necessary parts were replaced. Preventive parts also were replaced under warranty. Great job!

Installed new A/C and took the old one out. Put a new pad down and flushed the line set. Hooked it up and pressure tested the line to 400 psi. Put it in a vacuum down to 355 and released the charge. Will need to come back and do a start up.

On arrival all the zones were up to temp. He was 37 at an incoming temp of 32. Temp rise was 20.5 with et of 70. I performed a leak search. The leak search was inconclusive. I took a water sample. Replace tstat in the main area and programmed it. The old one was sending a emergency heat call when it wasn’t and it would register on the tstat. Changed some setting on the ewc board to make the stagging operate off the tstats and not the zone board timer. Changed the alpha pump to ramp speed 3. Geo btu output is with in operating limits and no refigernt leaks found. Left the manual for the thermostat on the table. Thanks Brad

Water was dripping from inside the geo unit, and leaking out. Found a few Spots that where not insulated well and put some more over the top to make them air tight. Cleaned up the water inside of the unit. Showed the customer where it was coming from and what I was going to do. We also went through all the filters and replaced them (hepa, electronic, and water filter). Did a quick proformence test, 6.5 gpm and a 9 delta t 29,250btus. The geo system is operating properly at this time. Thanks Brad
