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.

Hobaica comes out every 6 months to do an AC checkup. John was our technician this time and did a great, thorough job. He went above and beyond to make sure everything was running how it should be. They have always been great and hope to have John back the next time.

Ryan is by far the best Service Technician. He has been out several times and has done plumbing and AC repairs. Recommend Ryan and Hobaica for all of your home needs they do it all. Thanks Ryan!! Extremely impressed with Amer and Juan. They are thorough and gave me advice on taking better care of my unit by changing my filter more often, I did not know that. Asked about my carbon monoxide dector and I found out online it had been recalled, had Amer not mentioned the dector I would not have checked it out. They are very Iinformative about the services Hobaica offers. Can't say enough good about Hobaica, and Amer and Juan. I do recommend Hobaica to my friends.

John Miranda was wonderful. He wore a mask, as we do in our house, and wore shoe coverings when in the house. These may seem like small things but they demonstrate respect and professionalism. He gave our system a serious review and changes interior filters. I hope that the for our next seasonal service that Hobaica sends him out to us again.

I had Hobaica out for HVAC maintenance and duct cleaning. It was soon discovered my unit was limping along on its last leg and soon to bite the dust. Luckily it got me thru the summer. James came and helped us get a GREAT system that should keep us very comfortable in the future! Great service, very professional and courteous - all technicians who came out were also! You’ll spend a little bit of $ but as they say, you get what you pay for!!
