Air Conditioner Repair San Marino

Air Conditioner San Marino

Project Description

Pioneers Heating and Air recently answered the call of a San Marino, CA, homeowner in need of air conditioner repair. After reporting a musty, moldy smell rising from the vents, the client knew something was wrong. Upon inspection, our technician traced the issue to a leaking barometric relief hood on the rooftop unit. That was causing condensation to form on the heating system — creating a perfect breeding ground for mold growth. The mold caused an unpleasant smell in the vents and posed a health risk to the client's family. Without delay, our team replaced the leaking hood with a new, superior model. We also disinfected the unit to get rid of the mold and prevent it from spreading further. Lastly, we further checked the entire HVAC system to guarantee no other issues would arise. Our client was delighted with our work and grateful for our expertise, attention to detail, and quick response to solving the issue.

Rooftop units are necessary for many commercial and residential buildings. They ensure comfortable temperatures all year round with efficient heating and cooling. Yet, have you ever wondered what keeps your HVAC rooftop unit running efficiently and safely? Thanks to a small but essential component - the barometric relief hood. While often overlooked, it plays a crucial role in ensuring the proper operation of rooftop units. Without this component, rooftop units simply could not function! Let us explore how it works and the common problems involving these thin metal blades or flaps.

What is a barometric relief hood?

A barometric relief hood is an essential component of an HVAC rooftop unit. Often located on the side or top, this part contains a damper that opens and closes in response to pressure changes. It regulates air pressure and airflow to protect your system and maximize energy efficiency. When the air pressure inside the structure exceeds what is outside, this clever device responds with gravity-aided force, opening up pathways to let out the extra air. On the other hand, when the indoor pressure drops below that of the outside, the relief blades quickly close and ensure no further air can leave or enter. Thus, the barometric relief hood works tirelessly to keep your HVAC system safe and running smoothly!

What are the common problems with barometric relief hoods?

Barometric relief hoods can experience several problems that could affect their performance. Here are some of them:

Clogging: Over time, debris, dust, and dirt may accumulate on the hood's damper, leading to clogging and restricting airflow.

Damage: Barometric relief hoods are exposed to elements that may lead to damage, such as rust, corrosion, or dents.

Malfunctioning Damper: The damper inside the hood can malfunction, causing it to remain stuck in an open or closed position, leading to improper airflow or pressure regulation.

Poor Maintenance: Maintaining barometric relief hoods is not just a recommendation but essential. These hoods require regular cleaning and maintenance to ensure optimal performance. Neglecting this critical upkeep can have alarming effects, such as reduced efficiency and mold growth. Therefore, keep your air clean by regularly servicing your relief hoods!

Incorrect Installation: Improper installation can also cause problems with barometric relief hoods, such as incorrect airflow, incorrect pressure regulation, or damage to the unit.

A damaged barometric relief hood can cost you in multiple ways: reduced efficiency, poor air quality, increased energy usage, and operational issues. However, you can avoid all of this hassle by having an HVAC technician inspect and fix your barometric relief hood on a regular basis. Routine maintenance and check-ups can even stop the issue from arising in the first place. Taking preventive action now can save you from potential headaches down the line!
