Replacing a residential A/C compressor from $1,800 to $2,500.

So how exactly is your compressor the “heart” of your AC system? Well, just like your heart pumps blood throughout your body, the compressor pumps refrigerant throughout the AC system.

Refrigerant is the fluid that absorbs heat from inside your home and carries it outside (much like blood absorbs and carries oxygen throughout the body).

Here’s a more in-depth look at how your AC uses refrigerant to transfer heat and the role your compressor plays in this process:

Step 1: Your compressor pumps refrigerant from the outdoor unit (condenser) to the indoor unit (evaporator). During this stage, the refrigerant is a cold liquid that absorbs heat from inside your home.

As it collects more and more heat, the liquid refrigerant begins to turn into a vapor. Once it contains as much heat as it can hold, the (now vapor) refrigerant travels back towards your compressor, bringing the heat with it and away from your home.

Step 2: Once the vapor refrigerant arrives back at your outdoor unit, your compressor sucks in the refrigerant and heats the refrigerant up even more until it’s a superheated gas.

And because heat naturally moves to colder spaces, that super hot refrigerant can dump a lot of its heat into the cooler outdoor air. As it loses more and more heat, the refrigerant turns back into a liquid.

Step 3: Once the refrigerant loses most of its heat, your compressor sends it right back to your indoor unit to repeat the process until your home is cooled to your desired temperature.

It’s a bit more complicated than that, but that’ the gist of it!

Tip 1. Don’t suffocate your outdoor unit.

Go outside and check your outdoor unit. Make sure that all shrubbery, tree limbs, fences, etc. are at least 3 feet away from the unit. Never use decorative air conditioner “covers” either. Basically, anything that closely surrounds your outdoor unit prevents it from properly dumping heat into the outdoor air, causing your compressor to overheat and die.

Tip 2. Clean the condenser fins regularly.

Any buildup of dirt, bugs, etc. on the condenser fins can also impede the “heat dump” process and damage the compressor. The best DIY method for cleaning your condenser fins is to grab an Ac safe coil cleaner like this one.  Just follow the directions on the bottle and rinse the fins off with a hose on a gentle setting when you’re done.

Tip 3. Recognize the signs of low refrigerant (and act quickly!)

If your system is low on refrigerant (due to a refrigerant leak), your compressor will have to work harder to circulate enough refrigerant through the system and cool down your home. If you notice any of the signs below call a professional as soon as possible to fix the leak and recharge the system.

Signs of low refrigerant include:

  • An AC that runs constantly and still can’t cool your home
  • Higher-than-normal energy bills
  • Ice or frost on refrigerant coils
  • A hissing or bubbling noise coming from refrigerant lines

What I will tell you, is that the fair price of an HVAC installation will vary greatly based on the type of heating and air conditioning system installed, as well as the options needed or desired.

Galvez Air Conditioning & Refrigeration Inc. always is Honesty.  Don’t buy a new heating and air conditioning system until you troubleshoot first! You’d be surprised how often we used to get called out to peoples’ houses for a second opinion after they were told by some contractor that they needed a new HVAC system; they didn’t.

Varies depending on these factors:

Warranty Time:

5, 10 and 15 years. (Vary)

Size of your Air Conditioning:

Depend of tonnage refers to how much cooling the unit can provide in one hour.  Residential A/C units range anywhere from 1 to 5 tons with half sizes included.  The basic rule of thumb is that the larger the square footage of your home, the larger A/C size you have.

But…How can I to know the size of your A/C unit?

Easy, look for an information label on the side of the unit in your condenser.

  • Locate your A/C model number.
  • Search a number that’s divisible by 12. The number will be somewhere within the string of numbers/letters that is your model number.
  • The answer is the tonnage of your unit when your divide that number by 12.

Type of compressor:

There are 3 kinds of compressors available in Arizona

  • Variable speed compressors: offer unlimited levels of cooling based on what’s needed at the time (Recommended for Arizona temperatures)
  • Single-stage compressors:offer one level of cooling—HIGH and,
  • Two-stage compressors:offer 2 levels of cooling—HIGH and LO

Customer Reviews

  • positive review  Recently we discovered that our ac and heat was not working in our upstairs. Galvez Air was recommended to us on Nextdoor so I emailed him. He was very quick to respond and was at my house within hours. He was very honest with the repairs and had my unit up and running in no time. Jose was extremely friendly and even helped me set up my new smart thermostat after he was done. Galvez will now be my go to for any of my HVAC issues

  • positive review  Amazing service! Our AC unit started blowing hot air at 8pm and by 8:30 they were already taking a look at our unit. He was able to fix it in less than an hour. Very glad to have found him!

  • positive review  IF YOU EVER HAVE A/C ISSUES – THIS COMPANY (CEO JOSE GALVEZ) SAVED US – LITERALLY! I have lived in Arizona my entire life and I am 37. I have had several different homes from the West Valley to the East Valley and graduated from ASU in 2009. I have NEVER seen a Company care more about their customers than this Company. Our air conditioning went out 3 weeks ago and I am a full time attorney with two children who are in the midst of home schooling now with the pandemic as Gilbert is providing online courses for my children. I had been going outside to flip the breaker on and off as well as turning off my unit just to get by until the a/c repair company came out. I had FOUR companies come out to fix my unit and most told me that it would be 3 to 4 weeks more because of COVID-19 and other issues. My compressor, in the meantime, completely quit and my house inside raised to 95 degrees in temperature. I lost 3 animals and have heart issues. I was worried about my family and worried about how I would be able to provide for them if something happened as heat worsens my condition. My kind neighbors ended up giving me a place to stay while we waited for everything to get fixed. The 4th company to come out told me they would treat me right and promised not to price gouge. They ended up telling me it would be $11,200 to replace my a/c. They didn’t even climb into my attic to really find the problem. To make matters worse, I found out that they were only paying $3,500 for the unit they were charging me $11,200 to fix. I was at a loss and called a close friend asking for help. I have been struggling to make ends meet as several of my corporate clients have gone under with so much going on in the world and now I was trying to work from my neighbor’s home. I was worried about this personal emergency causing me to be unable to work for the clients that I have left. My fried recommended Jose to me and I was leary because all of the prior 4 companies had been so dishonest and seemed to not care about my predicament. Jose came out immediately and told me it would cost half the price of what every other company quoted me. He was honest, fair, and showed me why my A/C had broken down. He climbed into the attic and took time to actually find out what had happened. My A/C had broken twice last summer and this was the second time this summer. We moved into this home last year and I was starting to believe we would never find someone to fix the real problem. Arizona heat is brutal and a broken A/C disrupts Arizonan’s entire lives, especially with children in the home and pets. It is a health emergency. Jose treated it that way and told me everything was going to be okay. I had broken down crying because it was all so much and he was so professional despite how embarrassed I was to be a corporate attorney who couldn’t even handle everything at the point he came out because so much had been disrupted in our lives without having shelter we could live in any longer. Jose ordered the new unit the same day he came to my home to find out what was going on. He came with his employees next morning at 5:30 am to install and cleaned everything before he left. He saved me and my family in a way I could never repay. I will NEVER use another A/C company and will be referring EVERYONE to him. We are back in our home and finally back to being able to live our lives and work. Jose, you have saved an attorney and her family. Thank you for being honest, kind, professional, and so hard working. Thank you for giving us our home back.

  • positive review  I needed someone to come out and fix my failing AC because of a previous installers poor workmanship. I saw Galvez had great reviews in my area. I ended up calling late in the day, but he was still able to come out. Mr. Galvez and his assistant showed up promptly, looking neat and professional. They redid my previous installers work quickly and accurately. Mr. Galvez was super nice, and super knowledgeable. He completed the work correctly at a fraction of what the previous installer wanted to fix their own mistake. I will definitely be using Galvez again for my future checkups and maintenance.

  • positive review  Galvez AC recently installed a new Ac and furnace for me. He beat out 2 other estimates, one by 4000 dollars and the other one by over $ 1000. They arrived on time and went right to work, no breaks and done in under 6 hours. Honest and very knowledgable and friendly. I cannot recommend them enough. We are highly satisfied.
