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. And every part must be installed properly to work in perfect synchronization. Failure to follow industry standards during HVAC installation can result in poor performance. It can also be the cause of a higher energy bills, and a shorter service life.

Let’s discuss the different elements that play a role in any HVAC installation:

HVAC Unit Size

You could have 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 central air unit not only costs more to purchase. It will warm or cool your home very quickly. 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 it can create uncomfortable warm or cold spots in your home. Thus, reducing the efficiency of your HVAC unit.

The size of the unit is also important. Undersized systems simply don’t have enough power to do the job efficiently. A too-small system will need to run longer to achieve ideal temperatures. And this can result in unwanted expenses like a 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. This takes into considerations factors like your home’s construction and size. It would also include the design layout and orientation. That’s how they determine the correct air conditioning system size.

Heat Pump vs Straight Cool or Package Unit

There’s a simple difference between a heat pump, a straight cool, and a package unit.

Simply put, a heat pump unit goes into reverse to cool. Heat Pumps are great in all climates. But they can be tricky in the extreme cold if they’re not properly installed.

They can overheat easily. And this can cause the system to go into a bypass mode. In effect, it temporarily stops heating the house. To prevent this, electric heat strips are installed in the system as a secondary source. This way, 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.

Additionally, the condensers will most commonly be located on the ground. Unless, of course, 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.

Ductwork

Forced-air heating and cooling systems rely on a branching network of air ducts to circulate conditioned air throughout your home. Carefully install and balance the return and supply channel or duct for optimal performance. Over time, poorly designed or improperly maintained ductwork can develop leaks and gaps. And these faults impair efficiency and produce poor air quality. According to the Environmental Protection Agency (EPA), you can lose up to 20% of your air this way.

Sealing and insulating ducts eliminate leaks and improves energy efficiency. You don’t want to disrupt the balance between supply and return ducts. So it’s best to leave these task in the hands of qualified HVAC technicians. Improper sealing can actually worsen system efficiency.

Thermostats and Controls

Thermostats are connected to sensors on your HVAC equipment. These sensors signal the system to turn off or on according to the thermostat’s temperature setting readings. For proper operation, install both the thermostat and the indoor HVAC equipment in a draft-free location. Make sure they are away from air ducts.

Programmable thermostats allow you to preset different temperatures for different times of the day. You can schedule your HVAC system to automatically adjust temperatures. This is useful while you’re away from home or asleep at night. It’s a great way to still maintain energy efficiency with even thinking about it. 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.

Save yourself some trouble by choosing a system with a good season energy efficiency rating (SEER). When it comes to SEER ratings, the higher the number the better. SEER represent how energy-efficient your system is. So a unit with a 20 SEER rating is more energy efficient than one with a 13 score.

Today’s high-efficiency furnaces and air conditioners come with features like variable-speed blowers. These automatically adjust to the changing heating and cooling demands of your residential or commercial HVAC. So no more constant off-and-on operation. They execute a consistent delivery of warmed or cooled air. Plus they can still conserve energy at the same time.

HVAC Installation Costs

Factors that Affect your HVAC Installation Costs

You need a professional installation. And pricing varies depending on multiple factors. So it’s not just as simple as picking out a unit and having someone install it. Technicians check that the house is up to city code. If not, they can’t install a system. They also consider additional electrical needs. And they will check that the ductwork is in usable condition.

Along with the ductwork inspection, technicians will also check if you need a second return. 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. For example, will you need a crane? What’s the cost to install? Also, do you need to replace the condensate lines? Are there obstructions in the backyard or on the room that the installation team would have to move or workaround? It’s easy to think that a simple quote shouldn’t be so pricey. But there’s actually a lot more to it. And sometimes the best fix is an HVAC replacement.
