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 circulation.
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 recommendations.
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.
