Clark Heating & Cooling

About a year after buying my house in Phoenix, we noticed water dripping from through the thermostat during a storm. (Yes, the thermostat!)
After determining where I thought the leak was, I ended up calling Dave. His guy Ivan came over to patch up the condensation drain pipe (I explained I was confident this was where the water was entering the house).
After spending a solid amount of time «going to town» patching up any possible leak on the roof, Ivan was ready to leave and had me sign the invoice. I asked if he had any concern about mold, since there had been a handful of heavy storms before we called Dave. By his own suggestion, he went up into the attic to inspect it.
While we were up there, Ivan noticed daylight coming in through the seal of the AC unit to the roof. The unit wasn’t sealed correctly or possibly had shifted since being installed. Ivan pointed out that was the actual source of the leak. (And wasn’t easy to detect from on top of the roof.) He went back on the roof and reinforced the seal.
I was very satisfied because Ivan wasn’t at all in a hurry to get the job done and get out of there. His top priority was clearly doing the job right, and it’s because he had that thorough mindset that we were able to identify the source of the leak. We’ve had storms since then with no further issues.

My ac stopped blowing air into the house last night but I could hear the unit running on the roof.
Searched on Unilocal for good services, saw Clark within .6 miles from me and 5 star service.
Called him and he was at my house within 15 minutes! Very friendly and went right to work, came back down after 20 minutes or so; explained my control board is fried would be $ 400 repair to fix cooling/​heating. I was concerned with the unexpected bill, so he said he could bypass it to allow the cooling to work but the heating won’t work, so I’ll need to get it fixed before winter.
He bypassed it, wrote me a receipt and gave me his business card and magnet to replace the board when I can afford it. I payed $ 85 to fix my ac today, a regular service check is $ 55 but if he does any repair that’s free, and you just get charged for the repair.
I live alone and have no clue about ac units, so he answered all my questions and explained to me the problem and how a unit should work. Was very patient and understanding.
Will be using him for all my service needs from now on! Thank you!

I scheduled a check-​up for AC unit before the heat kicked in and couldn’t be happier with the service we received. Dave really knows his stuff. He took the time to answer all of my questions. I felt like he was honest and the price was great. As a fellow small business owner, I understand the value of providing excellent customer service regardless of how skilled you are in the service you are providing. I will definitely be recommending Clark Heating & Cooling to anyone I know who needs HVAC service.

We were in Scottsdale to check on our vacation rental, when our A/​C unit started pouring water… INSIDE the unit! With just 2 days before we were to leave, Dave was able to fit us in the NEXT day. He found the problem & was able to repair our A/​C! With summer approaching, it was imperative to have this taken care of & get ready for our next renters.
We would recommend ‘Super’ Dave without hesitation… prompt, reliable & fair rates.
«Mahalo», Dave, for taking care of us… on a Saturday, yet!
«A +++++»

You can depend on Dave! Our AC went out late Saturday afternoon. We called three service companies and Dave was the first to respond. He arrived promptly at 5:30 am Sunday as he said he would. He quickly diagnosed our problem – a very damaged blower wheel in the air handler. He had a supplier open up on Sunday to get a replacement for us. He took the fan motor with him to check it out, to be sure the shaft wasn’t bent. It was fine. Once the new blower wheel was in and the motor replaced we were good to go. Dave is very professional, knowledgeable and personable, too. He works neatly, no mess left behind. We are new to AZ, but we have found our AC guy! We highly recommend him to others.
By the way, we finally heard from the other two companies we called Sunday afternoon.

Amazing service! Dave came in and fixed the ac all up, he even told me things that would need to be replaced soon to prevent a summer break down. He wore slippers on his shoes to protect my floors when he came in from the outside. Very good company, would reccomend them to friends and family.
