Buying your first home is exciting—until something breaks. One of the most expensive systems in any house is the HVAC system, and if you’re not careful, that “new home HVAC warranty” you assumed would cover everything might leave you footing the repair bill. The problem? Most homeowners don’t realize their warranty is full of fine print, hidden loopholes, and conditions that can void coverage without warning.
Whether your HVAC system is brand-new or just new to you, understanding your warranty—and how to keep it intact—is the smartest move you can make. This blog breaks down the most common HVAC warranty mistakes first-time buyers make, and how to avoid the costly pitfalls that lead to early breakdowns and expensive fixes.
TLDR – Quick Guide
- Warranties aren’t automatic: You must register your HVAC warranty to activate it.
- DIY repairs or unlicensed work? That can void your warranty instantly.
- Skipping routine maintenance is a top reason claims get denied.
- Moving into a home with a new system? You might not be covered until you transfer the warranty.
- Always use licensed HVAC professionals, like Acuna’s Polar Aire Heating & A/C, for servicing.
Detailed Breakdown
Mistake #1: Not Registering Your HVAC Warranty
Many homeowners wrongly assume the HVAC warranty kicks in automatically when they move in. In reality, most manufacturers require the original owner—or the new owner, in a resale situation—to register the unit within a specific time frame, often 30 to 60 days after installation or purchase.
What happens if you don’t register? You’ll likely get reduced coverage or none at all, and the “limited” warranty could drop from 10 years to just 5—or less.
Pro Tip: If you’re not sure your system is registered, contact the manufacturer or a licensed HVAC contractor. Acuna’s Polar Aire Heating & A/C can help confirm warranty status and handle proper documentation if needed.
Mistake #2: Assuming the Warranty Transfers Automatically
Buying a home with a newer HVAC system? Don’t assume that the shiny unit is under warranty. Many warranties don’t automatically transfer to new owners—especially if the seller didn’t follow transfer procedures.
In some cases, the transfer must happen within a strict window (often 30–90 days post-sale) and may even involve a fee. Without this step, your warranty could be void, even if the system is only a couple years old.
Before closing on your new home, ask for HVAC documentation. If the seller can’t produce it, have an expert perform an HVAC inspection to identify issues before they become your problem.
Mistake #3: Using Unlicensed Contractors or DIY Fixes
When your system acts up, it’s tempting to call the cheapest handyman—or tackle the repair yourself. But most HVAC warranties clearly state that only licensed technicians can perform service or repairs without voiding coverage.
Hiring an unlicensed contractor, skipping permits, or using off-brand parts are all red flags to warranty providers. Even if the fix works, your warranty may be dead the moment someone unqualified opens the unit.
Stick with a licensed team like Acuna’s Polar Aire Heating & A/C for maintenance and repairs. It’s not just about getting the job done—it’s about preserving your coverage.
Mistake #4: Neglecting Regular HVAC Maintenance
One of the biggest reasons warranty claims get denied? Lack of routine maintenance. Even if your system is technically under warranty, the manufacturer can—and will—deny a claim if you can’t show proof that you kept the unit in good condition.
A professional HVAC maintenance plan keeps your system running efficiently and provides a documented history of care—something warranty departments look for.
Don’t wait until something breaks. Schedule seasonal checkups and keep digital or physical records of all maintenance visits.
Mistake #5: Ignoring Coverage Limits and Exclusions
Warranties don’t cover everything. Most limit coverage to specific parts (like the compressor or heat exchanger), and won’t cover labor, refrigerant, or damage from neglect, power surges, or improper installation.
Many homeowners don’t realize this until they file a claim and get hit with a big bill. Always read the fine print—and ask your HVAC provider to walk you through what’s covered and what isn’t.

FAQs
What happens if I never registered my HVAC warranty?
If you don’t register your HVAC warranty within the required timeframe, you’ll likely lose extended coverage and fall back to a shorter, limited warranty. Some manufacturers may not honor the warranty at all. Always check registration deadlines and complete the process quickly.
Can I transfer the HVAC warranty if I buy a resale home?
In many cases, yes—but it usually requires action within a set timeframe after closing. You may need to file paperwork and pay a transfer fee. Without proper transfer, the warranty may be void.
Are labor costs included in my HVAC warranty?
Most standard manufacturer warranties only cover parts, not labor. Extended warranties may include labor, but only under certain conditions. Ask your HVAC provider to explain your coverage in detail.
Is maintenance really required to keep my warranty valid?
Yes—routine maintenance is often a requirement for keeping your HVAC warranty active. Skipping scheduled service could result in claim denial. Having a professional HVAC maintenance plan in place is the best protection.
What voids an HVAC warranty?
Common warranty voiders include unlicensed repairs, skipped maintenance, use of unauthorized parts, and not registering or transferring the warranty. Always read the fine print. To stay compliant, work with licensed HVAC providers like Acuna’s Polar Aire Heating & A/C.
