Get the Most Out of Your AC Installation

While the rest of the country turns on their heaters and prepares for the chilly, windy, Halloween weather, we’ve got a few hot days approaching! If you were looking for a moment to buy an air conditioning unit, now is a perfect time!

Air conditioning installation is a touchy subject. Homeowners are always trying to save money by having an amateur or a family member set up their central air conditioning unit, but the truth of the matter is that this will most-likely yield negative results. Setting up HVAC in Los Angeles, CA isn’t a simple task, and one small problem in the installation can come with a plethora of expensive repairs down the line.

We’re not just trying to sell you service, we honestly don’t want you falling into the trap of a faulty AC installation, eventually calling us for repairs that could have been prevented.

Common Installation Issues

A poor AC installation can bring a long string of issues that might not be very noticeable. These systems need to be hooked up perfectly with air ducts and electrical systems. If done poorly, you can find errors in all of these fields, which could potentially damage your system and cost you money eventually.


Sizing is a huge part of AC installation since it will determine the exact cooling load that your system needs to create before it completes a full cycle. An air conditioner is built to cool a specific volume of space in your home, depending on how large it is, how many windows you have, how airtight it is, and other factors. An incorrectly sized AC will provide major problems down the line.

  • Too Small. An AC that’s too small for your home will not provide enough cool air to keep your home the temperature that is specified on your thermostat. This will leave your home warmer than it should be, and your AC working harder with a shorter lifespan.
  • Too Large. Isn’t bigger always better? Not in this case! An AC that’s too large won’t complete a full cooling cycle, which will cause strain on certain components of the system. If you’re looking for expensive repairs early on in the life of your system, this is the way to get there.

Wrong Refrigerant Levels

A thorough, professional technician will charge your AC with the exact amount of refrigerant necessary for peak performance. Often times, when an amateur installs an air conditioner, the refrigerant charge does not match the manufacturer’s exact specifications. This means that your system could have some major refrigerant problems later on, or it might not even work at all if the refrigerant levels are too low!

Air conditioners are built to stand the test of time. The easiest way to have your system fall apart years before it is supposed to, is by having an amateur install it. Don’t try to save money here, it’ll end up costing you in the long run.

That’s why you should contact JMS Air Conditioning and Heating for your next AC installation!
