Installing New Equipment? Use This A/C Installation Guide For Optimal Results
When it comes to a new A/C installation, do you know what you should expect
from your HVAC contractor? The initial setup of your cooling equipment
is a key element of ensuring that it serves you effectively and efficiently
throughout its entire life span. If you’re not sure what you should
be looking for when you work with your contractor on a new A/C installation,
here are a few guidelines to go by.
In order to provide you with a tailor-fitted air conditioner, your HVAC
contractor must perform a room by room Manual J heat loss/heat gain calculation.
Manual J load calculating is an industry-wide standard that enables your
technician to determine the exact cooling and moisture removal requirements
of your home. Manual D should also be utilized to size your ducts. If
your ducts are not properly sized, you may experience problems with uneven
heating and cooling throughout your house.
Before your new A/C installation takes place, your technician should check
your ductwork for leaks. Leaky ducts will diminish air circulation and
the right amount of cooled air will not reach each room. Any leaks detected
should immediately be sealed. At this time, your contractor may also recommend
the replacement or addition of ductwork to improve your household air
Too much or too little refrigerant can decrease your air conditioner’s
efficiency by up to 20 percent. Make sure that your technician verifies
that the refrigerant charge of your equipment is to the manufacturer’s
Don’t let your contractor upgrade your outdoor air conditioner without
also making updates to any corresponding indoor equipment like evaporator
coils. All parts which work together must be upgraded simultaneously or
else they will become incompatible, rendering them ineffective.
Be sure that your technician trains you on your new cooling system prior
to leaving. You should understand how the thermostat works, and how to
change or clean air filters. Additionally, make sure that you know who
to contact for service, if needed.
