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
