A poorly installed HVAC system can lead to skyrocketing energy bills, uneven temperatures, and frequent repairs. Whether it’s selecting the wrong size or hiring an unqualified technician, installation mistakes can cost you hundreds or even thousands of dollars over time.

In this brief article brought to you by professionals of HVAC services, Rooter Hero Plumbing & Air, we help you avoid these pitfalls with eight common HVAC installation mistakes.

1.    Choosing the Wrong Size Unit

An oversized system will short cycle, meaning it will turn on and off frequently. This leads to excessive wear and tear. A short-cycling HVAC system can have you scheduling premature and recurring heating and air conditioning repair.

On the other hand, an undersized unit will struggle to maintain the desired temperature. A unit that’s too small will work overtime and waste energy. Considering HVAC systems account for up to half of energy bills, this can be a big hit to your budget.

2.    Poor Ductwork Design and Installation

What good is an HVAC system without ductwork that distributes the conditioned air throughout your home? Poorly designed or improperly installed ducts can result in air leaks, weak airflow, and inefficient heating or cooling. This translates into higher energy bills and uncomfortable temperature variations.

Adequate ductwork must be correctly sized, properly sealed, and free from obstructions.

3.    Incorrect Refrigerant Charge

Refrigerant is the lifeblood of your air conditioning system, and too much or too little can severely impact efficiency and performance of the system. An undercharged system will struggle to cool your home while an overcharged system can cause excessive pressure and damage internal components in the HVAC system.

4.    Improper Placement of the Unit

Location, location, location. Believe it or not, where you place your HVAC unit matters more than you might think.

Installing an outdoor condenser in direct sunlight, in a cramped space, or too close to obstructions can reduce efficiency and airflow.Similarly, indoor units should not be placed near heat-producing appliances, drafty areas, or places with poor ventilation.

5.    Skipping the Thermostat Calibration

The thermostat must be adjusted, or calibrated, to make sure your HVAC system runs efficiently. After all, your system may overwork itself or fail to maintain the desired comfort levelsif your thermostat is reading the wrong temperature.

PRO TIP: Investing in a high-quality programmable thermostat (or smart thermostat) will help improve energy efficiency and comfort.

6.    Neglecting Proper Insulation

Your HVAC system is sensitive to the cold and heat just as you are. It relies on your home’s insulation to maintain a stable indoor climate.If your attic, walls, or windows are poorly insulated, then your HVAC system will have to work harder to heat or cool your home. During or before installation, assess your home’s insulation and make any necessary upgrades to improve efficiency.

7.    Not Ensuring Proper Ventilation

Not to be confused with ductwork, ventilation plays a crucial role in maintaining indoor air quality and preventing HVAC strain.Blocked or improperly placed vents can reduce airflow, cause rooms to be unevenly heated or cooled, and put unnecessary strain on your system. Make sure that all vents are unobstructed and strategically placed for optimal airflow throughout your home.

8.    Hiring an Unlicensed or Inexperienced Installer

Perhaps the biggest mistake homeowners make is choosing an unlicensed or inexperienced technician to install their HVAC system. While it may be tempting to go with the lowest quote, cutting corners on installation can lead to costly problems down the road.

Plus, leaving the installation to unauthorized technicians can void your warranty and give you headaches in the event that you need to file an insurance claim related to damage from the HVAC system.
