What HVAC Warranty Should I Expect on New Equipment?
A reasonable HVAC warranty isn't one big promise. It may treat the compressor, heat exchanger, other parts, labor, and installation work differently.
Before you approve new equipment for your Frederick County home, ask us for the exact manufacturer warranty for every model and a separate written explanation of labor or workmanship coverage.
Parts are not labor
A manufacturer may cover a failed component while you still pay diagnosis, removal, installation, refrigerant, or other listed costs. Ask us who handles each claim.
Registration can change terms
Some eligible programs use a registration deadline for extended coverage. Ask who registers each component and keep written confirmation.
Workmanship is separate
Installation workmanship coverage comes from us, not necessarily the equipment manufacturer. Get its duration, exclusions, and claim route in writing.
The certificate controls
A long number beside the word warranty doesn't answer what failed, who pays, or which costs are excluded. Read the model-specific terms before signing.
What does a new HVAC warranty usually cover?
Start by separating the layers. Manufacturer parts coverage explains which defective components may get replaced during the stated period. The term for a compressor or furnace heat exchanger may differ from the term for controls, boards, motors, coils, or other parts. A proposal that says only 10-year warranty isn't the full picture. Lennox warranty terms show why product tiers and components matter.
Labor coverage answers who pays to diagnose the failure, remove the failed part, install the replacement, and complete the repair. Installation workmanship is a separate promise from us. For a replacement project, ask us how ductwork, controls, electrical, the drain, and startup work relate to each layer.
- Manufacturer parts coverage
- Installer labor coverage
- Installation workmanship coverage
- Any optional service contract
How long should HVAC warranty coverage last?
There's no universal number. Current manufacturer programs show why: Carrier describes eligible registered replacement equipment with a choice between 10 years of parts-only coverage or 5 years of parts plus 3 years of labor. Lennox says its factory warranty covers parts only, although eligible registered equipment may offer a labor option. Those are brand-specific examples, not a promise for every model or installation. Compare the Carrier terms with the certificate for the equipment in your proposal.
A shorter term that clearly includes labor may fit your priorities better than a longer parts-only term. The useful comparison is the coverage that applies to the exact equipment, owner, property, and repair cost you're evaluating.
- Compare the compressor and heat-exchanger terms separately.
- Ask whether labor has a deductible or service fee.
- Confirm who administers a labor claim.
- Get spoken promises added to the written agreement.
Does registration change the coverage?
Registration deserves attention as soon as we install the equipment. Different manufacturers use different deadlines. Carrier describes a 90-day registration period for its Consumer Choice options on eligible replacement equipment; Trane says its Registered Limited Warranty is available for eligible products registered within 60 days; Goodman describes a 60-day period for eligible enhanced coverage, subject to exceptions. Treat those as program examples, not a rule for every brand. Read the certificate for your model and installation date.
A split system may include an outdoor unit, indoor coil, furnace or air handler, thermostat, and accessories. Decide in writing who'll register each component, then save the confirmation page or certificate and check that the name, address, installation date, model numbers, and serial numbers are correct.
- Ask for the registration deadline.
- Confirm who submits each component.
- Save the confirmation and serial-number photos.
- Check Maryland-specific and model-specific terms.
What should I read before signing?
Don't judge two proposals by the largest number beside the word warranty. The Federal Trade Commission advises buyers to check what repairs are excluded, what remedy is offered, and whether labor charges apply. Read the FTC warranty guidance alongside the manufacturer certificate.
Ask us for the full model number of every indoor unit, outdoor unit, coil, thermostat, and included accessory. Keep the final proposal, invoice, warranty certificates, registration confirmations, and serial-number photos together.
- The model-specific manufacturer certificate
- Parts terms for major components and controls
- Labor provider, duration, claim route, and charges
- Installer workmanship coverage
- Registration, transfer, maintenance, and exclusion terms
What can a warranty exclude?
The certificate controls. Common categories to check include labor, diagnosis, shipping, refrigerant, filters, maintenance, permits, access, and damage caused by improper use or outside conditions. That's a reading checklist, not a claim that every warranty excludes all of them.
Parts coverage doesn't guarantee comfort. Sizing, airflow, refrigerant, drainage, electrical work, controls, and installation quality still matter. Follow the equipment instructions, and keep dated service records, invoices, and receipts on hand.
- Read the required maintenance records.
- Ask what transfers if you sell the home.
- Confirm whether accessories have separate terms.
- Get every salesperson promise in writing.
What should I do if new equipment fails?
Start with the symptom and equipment identity. Photograph a fault code, note when the problem began, and find the model and serial numbers on the affected equipment. Retrieve the registration record and exact warranty certificate before assuming a repair's covered.
We still need to diagnose the failure first. Ask us which written term may apply, and have covered parts separated from homeowner-paid charges before authorizing work when circumstances allow. Follow the claim route in the certificate; the FTC recommends contacting the seller first and writing to the manufacturer if the seller doesn't resolve the problem.
- Do not promise coverage before diagnosis.
- Keep installer and manufacturer details together.
- Ask for the claim path and required documents.
- Separate parts, labor, and installation responsibility.
Questions homeowners ask next
Do HVAC warranties cover labor?
Sometimes a separate labor option covers it, from us or the manufacturer. Sometimes it doesn't. A parts warranty doesn't automatically pay for diagnosis, removal, installation, refrigerant, or service charges, so read the labor document to see who pays and for how long.
How do I register new equipment?
Ask us or the manufacturer for the model-specific process, deadline, and components that must be registered. Keep written confirmation and check the homeowner name, address, date, model numbers, and serial numbers.
Can poor installation affect a warranty claim?
It can affect responsibility for a failure and may fall under separate workmanship terms. Keep the installation scope, startup records, service records, and our written coverage together.
What warranty documents should I request before buying?
Request the model-specific manufacturer certificate, parts terms for major components, labor provider and claim route, our workmanship coverage, registration deadline, transfer rules, maintenance duties, and exclusions.
What should I do before authorizing a warranty repair?
Record the symptom, model and serial numbers, fault code, and registration details. Ask us to identify the failed component, explain which written term may apply, and separate covered parts from homeowner-paid charges.
