Ultimate Seasonal Hvac Maintenance Guide - LG Home Comfort

Your HVAC (heating, ventilation, and air conditioning) system is the heartbeat of your home. It’s the lifeline of comfort, regulating your indoor climate to keep you warm during the winter’s chill and cool during the sweltering heat of summer. However, as you might expect, your system requires regular maintenance to ensure it performs at its best.

In this comprehensive guide, we’ll walk you through the essential steps and considerations to keep your HVAC system running smoothly year-round. From the crisp days of fall to the scorching heat of summer, we’ll delve into the seasonal maintenance tasks that will help you optimize your system’s performance, extend its lifespan, and ensure your indoor air quality is top-notch.

Whether you’re a DIY enthusiast ready to roll up your sleeves or prefer to leave it to the pros, this guide will equip you with the knowledge you need to make informed decisions about your HVAC system’s care!

What Is HVAC Maintenance and Why Do You Need It?

HVAC maintenance is a proactive service provided by HVAC companies to ensure the optimal performance and longevity of heating, ventilation, and air conditioning systems. It involves a series of inspections, cleaning, adjustments, and repairs to keep HVAC systems running efficiently.

Professional HVAC companies typically offer comprehensive diagnostic testing that consist of a 24-point furnace service plan and/or a 26-point air conditioner service plan. These plans do not usually cover repairs, but the idea behind regular maintenance is to prevent major problems from occurring.

In order to understand why your heating and cooling system requires regular maintenance, let’s look at some examples of what can happen if you neglect to take care of it.

What Is Hvac Maintenance - LG Home Comfort

5 Common HVAC Problems Homeowners Encounter

1. Clogged Air Filters

Your system will naturally collect debris such as hair, dust, and dirt. Clogged air filters reduce airflow, strain your HVAC, and degrade air quality. Ultimately, if left untreated, dirty filters can strain motors and lead to burnout, higher electricity bills, and your system overheating. Yikes!

2. Frozen Pipes

This is a common problem with AC systems, often attributed to restricted airflow around the evaporator coil or issues with the refrigerant lines. Frozen HVAC pipes block heat exchange, causing system breakdowns, potential water damage, and costly repairs, especially during the winter.

3. Carbon Monoxide Leaks

Silent and deadly, CO leaks from faulty HVAC systems can lead to severe health risks and even fatalities, emphasizing the need for regular system inspections and maintenance.

4. Tripped Breaker

A tripped breaker happens when a circuit’s internal sensor overheats, shutting off the power immediately to prevent further damage. This common HVAC problem can leave homeowners without heating or cooling, requiring electrical troubleshooting to identify and resolve issues.

5. Uneven Airflow

Uneven airflow results in temperature inconsistencies across rooms, causing discomfort and overworking the system, leading to increased energy bills and potential wear and tear that could have otherwise been avoided with regular maintenance.

A Complete System Inspection

Hiring an HVAC technician for a professional inspection during the fall and winter is a critical maintenance step for several reasons.

  • Safety Assurance: HVAC systems, especially gas-powered furnaces, can pose safety risks if not properly maintained. Technicians are trained to check for gas leaks, ensuring your system operates without endangering your family.
  • Warranty Compliance: Many HVAC manufacturers require professional maintenance to keep warranties valid. Skipping these inspections might void your warranty, potentially leading to expensive out-of-pocket repairs.
  • Efficiency Optimization: Professionals have the expertise to fine-tune your HVAC for optimal performance, including calibrating thermostats, cleaning and lubricating components, and more.
  • Comprehensive Evaluation: HVAC professionals conduct a thorough examination of your system, inside and out. They can spot issues that homeowners might miss, ensuring your system’s overall health.

Inspect and Seal Ductwork

Proper duct sealing is a precise task that requires the right materials and techniques. While homeowners can visually inspect ducts for visible leaks, sealing and repairing ducts should be done by a professional to ensure a proper, airtight seal.

Complex Repairs

HVAC systems are intricate and can involve electrical, gas, and refrigerant components. Complex repairs, such as fixing malfunctions or addressing strange noises or odours require specialized knowledge and tools that only qualified professionals possess.
