This twisty part which is found in an A/C unit regulates the refrigerant flow for the indoor coil. It is called a thermostatic expansion valve, or TXV, for short. The TXV makes sure the A/C unit maintains maximum efficiency by allowing only a certain amount of refrigerant to flow into the evaporator. This control over the flow of refrigerant is necessary to make the evaporator as efficient as possible. It also prevents refrigerant from

When our AC broke just days before our big vacation, we got a quote from 2 well known AC businesses in the valley. We were so disappointed by them both because they had no quick solution and both were very costly. So I got a referral from a friend and called Clark Heating and Cooling and within minutes they sent someone over to give us a quote. We were in such a bind, dealing with no AC in 110 degree weather, with a small child and large dog, while trying to leave for our vacation. Clark's heating and cooling did not disappoint! In fact, they returned the next day and fixed our AC for a fraction of the cost. They were so friendly and fair, which my husband and I truly appreciated. They even followed up with us the next day to make sure everything was running okay. They are the best. Thank you all again!

CHC replaced my home AC system on 21Jun2024 (117F and muggy!). My old system was a high performing 19 yr old American Standard product where the compressor died of old age. My new system is same as my old system except a York product. It is a 5 ton split system with gas furnace / air blower / controller and evaporator heat exchanger, located in a central closet inside the house, and condenser heat exchanger / 3 phase compressor, located in a cabinet on the ground outside. It took two technicians Gabe, and Robert, 8 hrs to remove the previous equipment, install the new equipment, adjust controls/fluids and clean the jobsite. Everything but the house mounted control wires and refrigerant lines was replaced. The new system seems reliable and performs very well. The workspace in the central closet was very challenging requiring CHC to carefully plan and execute the disassembly/removal of the old equipment and assembly/installation of the new equipment. I was very pleased they completed all the work in one day at a price under $10k. There were no unexpected costs or changes and CHC disposed of all the old equipement and related trash. Robert and Gabe were very professional and surprisingly robust in the horrible heat. Job well done!

Holy Cow! I full well expected any company that came out for a tune up was just going to tell me to give up on my unit and give them 10k for a new one....and then you send me Sam! Let's be real, all true heros are named Sam. Uncle Sam, Sam Adams, Sam from LOTR who is the only reason the ring got destroyed...and YOUR Sam. Kind, respectful, friendly, and a pro! Im beyond thrilled. He came and was thoroughly going over everything while putting up w my questions and not giving up on my old gal AC while she is kicking. Thank you guys for showing me AC companies in the valley can in affect be honest.
I appreciate you and all you did and can't wait to call you out for all AC needs,

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.
