The Basics of HVAC Installation
by The Cooling Company, on Dec 24, 2013 3:20:16 AM
The acronym "HVAC" stands for heating, ventilation and air conditioning. Central HVAC systems include a variety of components and equipment, all of which must be installed properly to work in perfect synchronization. Failure to follow industry standards during HVAC installation can result in poor performance, higher energy bills and a shorter service life.
Whether it's a furnace, a conventional air conditioner or a heat pump that provides both heating and cooling, nothing is more important to a successful installation than getting the system size right. An oversized unit not only costs more to purchase but will warm or cool your home so quickly that it will cycle off before household air has had time to return to the equipment for re-conditioning. This can cause the air to feel musty, sticky or clammy and can create uncomfortable warm or cold spots in your home.
Undersized systems simply don't have enough power to get the job done efficiently. A too-small system will need to run longer to achieve ideal temperatures, which can result in a costly but necessary air conditioner repair and a premature replacement. HVAC systems are sized according to the amount of heating and cooling that they generate. A reputable HVAC technician will conduct a load calculation that considers factors like your home's construction, size, design layout and orientation in order to establish the correct system size.
Forced-air heating and cooling systems rely on a branching network of air ducts to circulate conditioned air throughout your home. For optimal performance, the return and supply channels must be carefully installed and balanced. Over time, poorly designed or improperly maintained ductwork can develop leaks and gaps that impair efficiency. According to the Environmental Protection Agency (EPA), up to 20 percent of the air that travels through ductwork in the average home is lost to leakage.
Sealing and insulating ducts eliminates leaks and improves energy efficiency. In order not to disrupt the balance between supply and return ducts, however, it's best to leave the task in the hands of qualified professionals. Improper sealing can actually worsen system efficiency.
Thermostats and Controls
Thermostats are connected to sensors on HVAC equipment that signal the system to turn off or on according to the thermostat's temperature setting readings. For proper operation, both the thermostat and the indoor HVAC equipment should be installed in a draft-free location away from air ducts.
Programmable thermostats allow you to preset different temperatures for different times of the day. By scheduling your HVAC system to adjust temperatures while you're away from home or asleep at night, you can reduce your energy expenses by 10 percent or more, according to the EPA. Some advanced models let you control settings from your computer or smart device.
Today's high efficiency furnaces and air conditioners come with features like variable-speed blowers that automatically adjust to the changing heating and cooling demands of your home or business. Instead of constant off-and-on operation, they execute a consistent delivery of warmed or cooled air while conserving energy at the same time.
In addition to ensuring that an HVAC system is installed properly, it's important to verify that you can trust the technician who enters your home as well.
