"I literally charge 90 an hour to clean the outside and it's usually always done in an hour."

A widow said a routine HVAC service call took an alarming turn after a technician quoted her about $10,000 to clean parts of a heating and cooling system that was still operating normally.

She described the experience on Reddit's r/HVACAdvice forum.

What happened

In the post, the homeowner said the 12-year-old HVAC system in her 1,700-square-foot house was working fine and that she changed the filters every month.

Even so, after a tune-up, she said the company recommended roughly $10,000 to disassemble and clean the furnace and air-conditioner fans.

Commenters quickly responded, saying the estimate did not sound reasonable.

One person wrote, "Run. This should be illegal," while another said the company was "definitely trying to scam you" because "10K-15k should be close to enough to replace your furnace and AC entirely."

Because the offer came after a standard service visit rather than a detailed explanation, some readers viewed it as a case of aggressive upselling. Several also compared the quote with their own experiences to show how extreme the number seemed.

One user said, "I literally charge 90 an hour to clean the outside and it's usually always done in an hour," and another added, "I just got a full Goodman split system installed for $4500." Those were personal examples, not universal pricing guidelines.

Another commenter said, "They're taking you for a ride," and someone else called the quote "worse than a Cadillac dealership."

What should homeowners do?

If a routine checkup starts to cost nearly as much as replacing major equipment, getting a second opinion before agreeing to the work is a sensible move.

Many commenters advised the homeowner to have another contractor inspect the system before approving any expensive repairs. They urged her to "Find a new company" and said the original contractor should stay away until an independent professional confirms whether anything beyond basic maintenance is actually needed.

If replacement does become necessary, Palmetto says it can help homeowners review HVAC options and lower energy bills with newer, more efficient systems and heat pumps.

Palmetto's Comfort Plan network also connects homeowners with vetted installers and more efficient heating and cooling solutions that may be a better fit for the home, especially when one quote seems far outside the norm.

For older systems nearing the end of their useful life, replacement may offer better value than paying for questionable service visits. For homeowners not ready to cover the cost upfront, Palmetto's Comfort Plan offers $0-down options that can reduce heating and cooling costs by up to 50%, along with 12 years of free maintenance.

One commenter summed it up bluntly: "Your equipment may be just fine or it could need a cleaning for a tenth of that price. Your house will not burn down."
