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
Ok, so this round canister-looking part in the picture is not actually a flux capacitor, and it can’t help you time-travel, but it really is called a run capacitor. The run capacitor plays a very important role in how well the air conditioner runs.
What a Run Capacitor Does
A run capacitor's function is to start compressors and motors and keep them running at a normal amp draw level. These components will commonly fail in
At Clark Heating & Cooling, we always emphasize the importance of routine maintenance to keep your air conditioner in top shape. Are you curious about what exactly goes into our routine maintenance checks? We perform a detailed 22 point inspection, making sure everything is working properly.
Here are the items we check in our 22 point inspection
* Freon levels per manufacturer’s specifications, amp draws on the blower motor, outdoor fan motor, and compressor *

Approximately 3 weeks ago, I had a Heating/Air Conditioning tech come to my residence to conduct the annual inspection of my AC systems before the summer heat arrived. He was from a supposed well regarded Phoenix company with good reviews. It went down hill after that.
When completed, the tech reported that he would replace 4 of my electric motor run capacitors to the tune of $655.00. He also said that the R-22 refrigerant in my 5 ton main floor AC unit was low on refrigerant and that the unit was 'not cooling'. And finally, he stated that both of the ceiling mounted air filters were dirty.
Here's the rub.
Replacing a capacitor, though you should know what your doing to prevent being shocked, is not rocket science. Though I didn't really believe my capacitors were failing, I'm one who believes in preventative maintenance. So I replaced them myself with high quality Made in America capacitors for $130.00. It takes about 5 minutes each to replace them. Not $655.00.
The tech didn't know that two days before he arrived, I had replaced both my air filters with brand new clean ones. They weren't dirty though it would help if he opened the air handler door to check them in the first place.
Finally, the R-22 refrigerant.
R-22 is being phased out by the EPA for supposed damage to our atmosphere. This tech said that he would replace both of my AC units to the tune of just under $13,000.00 and that if I ordered them "today", he would not charge me to top of my supposedly low R-22. I said the one 5 ton unit was only 4 years old. I said no.
I then contracted with another Phoenix HVAC company, "Clark Heating and Cooling".
Dave, the owner, was professional, customer service orientated and above all, runs an "honest" company. He has to be, his name is on the side of his service trucks.
The tech who arrived from Clark HVAC, Eric , was on time and a knowledgeable and courteous HVAC tech. I told him that I was having doubts believing the R-22 refrigerant in the big 5 ton unit was low and as the previous tech stated "the one AC isnt' cooling". Which is a strange assumption since it was COLD in this home when he arrived. 2 + 2 isn't 5.
The Clark Heating and Cooling tech quickly inspected the 5 ton AC in both the air handler unit in the attic and the condenser and reported that this AC unit was working "perfectly" and was not low on R-22 refrigerant nor was there anything else wrong with it. Running perfectly. I realize this is a wordy review, but when you find an HONEST contractor, you should award him with praise and your continued business and let people know about this small, professional and most of all, honest contractor. I HIGHLY recommend "Clark Heating and Cooling" and Dave Clark and his staff, Ivan and Eric for all of your HVAC needs.
