Understanding Furnace and Air Conditioner Warranties

HVAC Warranty Mistakes Infographic

When investing in a new furnace or air conditioner, understanding the warranty that comes with your equipment is as crucial as understanding its energy efficiency and features. Warranties not only offer peace of mind but also protect your investment. However, many homeowners may find themselves puzzled by the terms, conditions, and how to ensure their warranty remains intact. This guide will demystify furnace and air conditioner warranties, highlighting what manufacturers expect and how a maintenance plan can safeguard your warranty.

How Do Warranties Work?

Warranties on furnaces and air conditioners are promises made by manufacturers to repair or replace parts of your equipment should it fail due to manufacturing defects within a specified period. These warranties generally cover the cost of parts, but not always the labor required to replace them. The length and coverage of these warranties can vary significantly between manufacturers and models.

What Customers Need to Know

As a customer, it’s important to register your new equipment with the manufacturer shortly after installation. Failing to do so can sometimes result in a shorter warranty period. Always keep a copy of your purchase and warranty registration for your records.

Be aware that most warranties require the equipment to be installed and serviced by licensed professionals. DIY installations or repairs can void your warranty. Additionally, warranties usually do not cover damage caused by improper use, neglect, natural disasters, or theft.

Manufacturer Expectations

Manufacturers expect customers to maintain their equipment according to the guidelines provided in the owner’s manual. This includes regular inspections and routine maintenance by a certified technician. Neglecting these can void your warranty, leaving you uncovered when you need it the most.

The Role of Maintenance Plans

Just like a car needs regular oil changes to keep running smoothly, your furnace and air conditioner require regular maintenance to operate at peak efficiency. Many HVAC companies offer maintenance plans that ensure your equipment is inspected and serviced annually by a professional. These plans not only help keep your system running efficiently but also keep your warranty intact. During these maintenance visits, technicians can spot and fix minor issues before they turn into major problems, potentially saving you from costly repairs down the line.

“Oil Changes” for Your Equipment

Think of maintenance for your HVAC system as you would an oil change for your car. It’s a relatively small expense that prolongs the life of your equipment, ensures it runs efficiently, and prevents voiding your warranty. Regular maintenance checks typically include cleaning or replacing filters, inspecting electrical components and connections, checking the thermostat settings, and ensuring the system cycles on and off properly.

Skipping these “oil changes” can lead to decreased efficiency, higher utility bills, and even system failure, none of which are covered under warranty if due to neglect.


Furnace and air conditioner warranties are valuable protections for your investment in comfort and efficiency. By understanding how these warranties work, what is expected from you, and the importance of maintenance, you can ensure your HVAC system is covered for years to come. Remember, investing in a maintenance plan is not only about keeping your warranty valid but also about ensuring your home remains a comfortable sanctuary regardless of the season. So, consider it not as an additional expense, but as a crucial part of your home’s upkeep. Contact us to schedule a maintenance visit so we can keep your equipment running strong!
