What Factors Are Taken Into Consideration When Installing a New HVAC Unit?

Installing a new HVAC system is always a significant investment. It enhances the comfort level in your home and can also increase your property’s value. However, there are many factors to consider when picking out a new HVAC system to install.

Indoor Air Quality

Indoor air quality is critical to a comfortable home. HVAC systems can include components such as ventilation systems and air purifiers to clean the air. Without sufficient air filtration, irritating contaminants like pollen, dust, and more can enter your space and linger. Some HVAC models can have multiple stages of air filtration beyond a simple filter.


Zoning is when the temperature in different areas of your home can be independently controlled. In traditional HVAC systems, this is usually done with a series of dampers in the ductwork. With a ductless multi-split HVAC system, each interior unit has its own temperature and airflow control. Zoning allows occupants to adjust areas to their specific comfort levels. Certain zones can also be shut off to save energy when those areas are unoccupied.

Energy Efficiency

Energy efficiency is another important factor to consider. More efficient HVAC systems will use less energy to do the same amount of work, which can make a significant difference in your energy bills. In addition to these savings, energy-efficient HVAC systems reduce your home’s carbon footprint. This is ideal for environmentally conscious homeowners.

Unit Size

The size of your HVAC unit is also important. Your HVAC system needs to be powerful enough to sufficiently warm or cool your home. A larger home will need a more robust outdoor unit. If you choose a ductless mini-split HVAC system for your home, the size and power of your interior units will also matter.

Airflow and Circulation

Good airflow and circulation are vital to a comfortable home. Without good airflow, you may notice unwanted cold or hot spots in different parts of the house. The number of vents in your home can affect the airflow and circulation with traditional HVAC systems. With mini-split systems, the number of interior units is the deciding factor.

Noise Level

How noisy an HVAC system is during operation is also an important factor. People who work from home and need to concentrate will likely appreciate an HVAC system with a quieter operation. Additionally, consider the outdoor unit placement. Loud outdoor units placed near bedrooms with light sleepers can also be problematic.


Check the coverage and terms that are offered by the warranty of the HVAC manufacturer. If the HVAC unit you are installing has a longer warranty period, this can indicate that the manufacturer is more confident in the quality and life span of their product. You also want to be familiar with the maintenance requirements listed in the warranty, because failing to keep up with regular maintenance can result in a claim being denied.

Service Accessibility

Consider how easy it is to access the different areas of your HVAC system for a technician to maintain or repair it. Outdoor unit placement, ductwork location, electrical wiring, mini-split interior unit location, and more can affect accessibility. On top of maintenance ease, good accessibility can help technicians diagnose and fix a problem more easily if one occurs.

Long-Term Costs

It’s easy to get stuck on just the initial cost of the HVAC system itself. However, it’s essential to consider the long-term costs and make sure you are getting the best deal for your comfort. The price of the unit, installation, ongoing energy costs, maintenance frequency, HVAC lifespan, and more all contribute to the overall cost of your system.

Manufacturer Reputation

Make sure the manufacturer has a good reputation. They should have good reviews for their systems and infrequent issues. Not only should their system be built to the highest standards, but it also matters how good the company support is.

Experienced HVAC Technicians

Since HVAC systems are a big investment, it’s important to have qualified and experienced HVAC technicians from a reputable HVAC company doing the installation. Less experienced HVAC technicians can make mistakes during an installation, and these can cause problems with your system down the road.

As you can see, there are a lot of things to consider when installing a new HVAC unit in your home. While you can figure out many of these with a bit of research, an HVAC service company can help by giving recommendations based on your needs.
