What Every Homeowner Should KNOW Before Purchasing a New AC Unit

Let’s face it, for the vast majority of homeowners, we know that installing a new AC unit is not a do it yourself, weekend warrior job.  So, before you call an expert, it’s important to educate yourself as a consumer in order to make the right choices for your family’s comfort.

Understanding the Right Size

In many homes, the existing system is oversized due to the fact that the owners have made improvements to make the home more energy efficient through time.  For example, adding double pane windows and insulation to a home means that the unit that was previously properly sized is now oversized.  Units that are too large will cycle on and off frequently.  As a result, there will be swings in room temperature and the unit will not remove sufficient humidity from the home.  This process wastes energy and also increases the chance the unit will fail before its time.

On the other hand, units that are too small can also increase the likelihood of a breakdown as well.  The too small unit must work harder and stay on longer than a properly sized one.  As the days grow warmer, the unit may not have enough cooling capacity to cool the home sufficiently.

How to Determine the Right Size

In order to select the correct size of air conditioner, contractors should refer to Manual J.  The software considers several factors in choosing the right sized unit.  These include the orientation and size of the home, the amount of insulation, the home’s windows and the number of people living in the home.  In addition, the contractor should refer to Manual D, a companion to Manual J that helps if ductwork changes will berequired during the installation.

By referring to these calculations as well as other factors, the contractor can determine the proper cooling load for the home.  Determining the cooling load is the only correct method to choose the correct size for the home’s new AC system.

Consumer Alert:  Ask your Air Conditioning Professional “how did you determine the size unit that my home needs?”  If the contractor says they use the BTU figure or the square footage of the home, they are not including all of the factors needed to make a sound recommendation.  It’s time to get a second opinion before making a commitment to buy.

Installing the New AC System

While do-it-yourself homeowners may consider making the installation of the new system for themselves, this is a job that should be left to the qualified contractor.  Even if the homeowner does part of the job for himself, a contractor is still needed for:

Charging the system with refrigerant.  The law requires EPA-certified technicians for handling this chemical.  If an old system is being removed, a contractor must remove any R-22 refrigerant from the old system and process it per EPA regulations.

– Connection of the unit to the circuit panel and any other high voltage electrical wiring.  The contractor must also verify the current electrical system meets the demands of the new home AC system.

– Inspection of the installation.

– When it is time to have the new home AC system installed, the compressor should be installed in a shady place, preferably on the east or north side of the home.

-Manufacturer warranties are typically contingent on the equipment installed by a certified & licensed contractor.

The purchase of a new Comfort System is a large investment and it is worth choosing a qualified professional to help guide you in making the choices for your home that are designed for how you live and using the highest industry standards.

Hello, just a little note to tell you how great our Technicians were today.Ivan and Troy showed up a little ahead of schedule, met with us, checked out the work areas and got right to work. And they did a fantastic job! I thought I was going to hear all kinds of banging and all kinds of noise but instead it was just a little bit of noise and the cool sound of Ivan whistling... reminded me of my Dad, he always whistled to, it was great.Troy was also quietly working outside.Upon completion of the work Troy and Ivan showed us their work and how the new thermostat worked.They did a great job with the installation, very professional work! I've seen a few air conditioning/furnace installations over the years when building homes with my dad and cousin...and these two technicians (Ivan and Troy) are obviously very good at what they do, and very good with the customer service experience they exhibited to us!!And personally I think they both definitely deserve a raise!!! And no, they didn't ask me to say this, LOL. It's obvious they're humble guys that would never ask for something like this, but they definitely deserve a raise...at minimum some fantastic kudos to some great Hobiaca Technicians!Kudos to Ivan and Troy for a job very well done!Thank you,Jack and Jackie Guzman11/11/2021
