First of all, let’s start with the most basic question someone could have around an HVAC installation… What does HVAC stand for?
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 shorter service life.
Let’s discuss the different elements that play a role in any HVAC installation:
HVAC Unit Size
Whether it’s a straight cool system, a package unit, 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 and bottom-line reduce the efficiency of your HVAC unit.
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 costly repair and 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.
Heat Pump vs Straight Cool or Package Unit
The difference between a heat pump, a straight cool, and a package unit, is a heat pump unit goes into reverse to cool. Heat Pumps are great in all climates but can be tricky in the extreme cold if they’re not properly installed. They can overheat easily, causing the system to go into a bypass mode and temporarily stop heating the house. To prevent this, electric heat strips are installed in the system as a secondary source, so the heat pump doesn’t have to work so hard.
Package units are a little more simplistic and have a faster installation time. A package unit is the whole “package” because it heats, cools, and circulates air from a single rooftop unit. These are most popular for commercial buildings.
Straight Cool Split Systems are the most common for residential homes. The condenser, furnace, and coil are all separate components that work together to regulate the temperature. The condensers will most commonly be located on the ground unless the house was specially designed to keep the condensers out of sight on the roof. These systems work efficiently to keep houses at just the right temperature.
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 channel or duct must be carefully installed and balanced. Over time, poorly designed or improperly maintained ductwork can develop leaks and gaps that impair the efficiency and produce poor air quality. 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 eliminate 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 HVAC technicians. Improper sealing can actually worsen system efficiency.
Thermostats and Controls
Thermostats are connected to sensors on HVAC equipment that signals 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. If you are looking for energy efficiency 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 residential or commercial HVAC. Instead of constant off-and-on operation, they execute a consistent delivery of warmed or cooled air while conserving energy at the same time.
Factors that Affect your HVAC Installation Costs
Factoring the cost of a new unit breaks down to many things. It’s not just as simple as picking out a unit and having someone install it. Technicians look to see if the house is up to city code to be able to perform an installation, considers additional electrical needs, and checks to see if the ductwork is in usable condition. Along with the ductwork inspection, technicians will also calculate to see if a second return will be needed. A new unit is no good if it continues to break down after being starved for air.
There are other factors to think about as well, such as will a crane be needed, do the condensate lines need to be replaced, are there obstructions in the backyard or on the room that the installation team would have to move or workaround? While it’s easy to think that a simple quote shouldn’t be so pricey, there’s actually a lot more to it.
