Understanding HVAC System Warranties & Coverage

When investing in a new heating or cooling system, your HVAC warranty can be just as valuable as the unit itself. A strong warranty protects you from unexpected repair costs and ensures your system performs reliably for years. Unfortunately, many homeowners don’t fully understand what their warranty covers—or what actions can accidentally void it.

At Hart Heating & A/C, we help homeowners across Lubbock make confident, informed decisions about their comfort systems. Here’s what every homeowner should know about HVAC warranties in Lubbock and how to make sure you’re fully protected.

Manufacturer vs. Labor Warranties

Not all warranties are the same — and most HVAC systems actually come with two types of coverage:

Manufacturer Warranty:
This covers the cost of parts that fail due to defects in materials or manufacturing. For example, if your compressor or heat exchanger stops working within the warranty period, the manufacturer typically provides a replacement part at no charge.
Labor Warranty:
Offered by the HVAC contractor, this covers the cost of labor needed to repair or replace parts under warranty. While manufacturer coverage might last 10 years, labor coverage is usually shorter — often between 1 and 3 years — unless you purchase an extended plan.

Together, these two warranties protect both the parts and the work involved in keeping your system running.

Pro Tip: Always ask your installer how long each warranty lasts and whether registration is required to activate it.

What’s Typically Covered

Most HVAC warranties in Lubbock include coverage for key system components:

Compressors and coils
Heat exchangers
Internal functional parts (like fans and motors)
Major electrical components

This coverage ensures you’re not stuck with huge HVAC repair bills due to premature part failure. However, coverage always depends on the manufacturer’s terms, so reading the fine print is essential.

What’s Not Covered

There are limits to every warranty — and knowing them can save you frustration later. Most HVAC warranties don’t cover:

Regular wear and tear or maintenance issues like dirty filters or clogged drains
Improper installation or unlicensed repairs
Neglect or lack of routine maintenance
Damage caused by weather events or power surges

Skipping professional service visits or performing DIY repairs could void your warranty entirely, so it’s best to leave system care to a certified technician.

How to Keep Your Warranty Valid

Many homeowners lose coverage without realizing it. To protect your HVAC warranty, make sure you:

Register your system: Most manufacturers require online registration within 60–90 days of installation.
Schedule regular maintenance: Documented maintenance from a licensed contractor like Hart Heating & A/C proves you’re properly caring for your system.
Use original replacement parts: Off-brand parts can void coverage.
Keep your receipts and records: You may need proof of maintenance or installation to file a claim.

A little organization goes a long way in protecting your investment.

Extended Warranties — Are They Worth It?

Extended or supplemental warranties can add extra protection beyond standard coverage. For homeowners who plan to stay in their Lubbock home long-term, they’re often a smart investment.

Peace of mind: No surprise costs for major parts or labor.
Transferable coverage: Helps boost resale value.
Custom protection: You can choose what systems and parts to include.

Before purchasing, compare the terms to your manufacturer’s warranty so you’re not paying for duplicate coverage.

Why Warranty Compliance Matters

Maintaining your warranty isn’t just about paperwork — it’s about keeping your system running efficiently and safely. By following warranty terms, you ensure your HVAC unit:

Performs at peak efficiency year-round
Lasts longer with fewer breakdowns
Stays covered for costly part replacements

That’s why Hart Heating & A/C always handles installations and maintenance by the book, so our customers never have to worry about voided warranties or overlooked details.
