The Life Cycle of an HVAC System

Installation of an HVAC System

Getting a new HVAC system is a significant decision. Installation can be somewhat overwhelming given all the options available, and you need to consider several factors. To help you get started, we’ll address the first crucial step: choosing the right HVAC unit.

Choosing the Right HVAC Unit

When it comes to selecting the right HVAC unit, there are several things you need to take into account.

Efficiency rating: The efficiency of your unit will determine how much you spend on energy bills. Look for units with high efficiency ratings, as they’re designed to provide optimum heating and cooling while using less energy.
Heat pump or central AC: Depending on your climate and heating needs, you may opt for a heat pump, which can provide heating and cooling, or a central AC unit, which only provides cooling.
Size of your building: The size of your building will dictate the type of HVAC system you need. While split systems might work for smaller spaces, larger buildings may require packaged systems.
Cost: The HVAC system cost varies depending on the type and model you choose. Be sure to compare quotes and consider the long-term running costs.

Don’t overlook the importance of reviews too. Consumer reviews and HVAC specialists can provide valuable insights into the pros and cons of different models.

The Installation Process

Proper HVAC installation contributes to the longevity and efficiency of your system. Typically, the process involves five main stages:

First, the HVAC pro will evaluate your current system and recommend the best replacement if needed.
Next, the old system is dismantled and removed for the new installation.
The HVAC tech installs the outdoor unit (usually a heat pump or central air conditioner), which removes heat from your business.
The indoor unit, such as an air exchanger or air handler, gets installed next. This element controls the air inside your building, ensuring proper circulation and filtration.
Finally, the HVAC specialist connects the indoor and outdoor systems, checks for adequate refrigerant levels, and tests the system to ensure it’s running correctly.

After installation, your HVAC professional should take care of some post-installation procedures.

Post-Installation Procedures and Checks

After your new HVAC system is installed, several checks are necessary to make sure it’s functioning correctly. This includes inspecting ductwork for leaks, testing system controls, and measuring airflow. Improperly installed HVAC systems can lead to increased energy bills and subpar indoor air quality.

Maintaining and Repairing Your HVAC System

Regular maintenance of your HVAC system extends its lifespan, improves efficiency, and prevents costly repairs. So, let’s explore how often you should schedule maintenance and when to consider repairs or replacements.

Scheduling Regular HVAC Maintenance

Professional maintenance is a great way to keep things running like they should. Skilled HVAC techs should service your system at least once a year. They’ll carry out comprehensive checks and repairs so the system operates at peak performance. Regular maintenance can preemptively identify problems, but how do you know when it’s time for a repair or a replacement?

When to Repair or Replace Your HVAC System

The decision to repair or replace your HVAC system depends on several factors. Age, energy efficiency, and repair costs all play critical roles. As a rule of thumb, if your system is over 10 years old and frequently breaking down, a replacement might be more cost effective.

However, if the unit is newer and the repairs are minor, fixing the problem is often the better choice. Be on the lookout for erratic performance, high energy bills, or uncomfortable indoor temperatures. These are clear indications that your system needs attention, and consulting with an HVAC specialist for a risk assessment will guide you on the best course of action.

Replacing an HVAC System

There comes a time when every heating, ventilation, and air conditioning system requires replacement. Knowing when it’s the right time to replace your HVAC can optimize comfort and cost savings. Selecting a suitable replacement system is also crucial.

When to Consider HVAC Replacement

An HVAC system typically lasts 15–20 years, though units can fail sooner or keep running longer. There are several telltale signs your HVAC is ready for replacement:

Frequent repairs and rising maintenance costs
Inability to maintain comfortable indoor temperatures
Spikes in energy bills despite normal usage
Loud, strange noises from vents or unit
Visible damage like rust or cracks
Refrigerant leaks

If your HVAC system is over 15 years old, it may be wise to replace it as a precaution, even if you aren’t yet experiencing issues. Efficiency and capacity tend to decline with age, and repairs get harder as parts wear out.

Upgrading before your HVAC fails allows you to swap it at your convenience rather than requiring emergency replacement at a high cost when it inevitably breaks down.

Choosing a Replacement HVAC System

Selecting the right replacement HVAC system involves weighing factors like:

Building size and layout: Systems need to accommodate the space and ideal temperature of your building.
Local climate: Heat pumps work well in temperate climates, while hot/cold regions need robust AC and heating.
Efficiency rating: Upgrading to an ENERGY STAR-certified system can yield substantial energy savings.
Features: Consider smart connectivity, multi-stage performance, humidity control, and more.
Warranties: Aim for 10–15 years of coverage on the compressor and five years on parts.

An HVAC professional can assess your building and provide system recommendations for your situation. Getting multiple quotes also helps you find an ideal balance of performance, features, and fair pricing.
