What the CPSC Data Shows

Heat Pumps (CPSC product code 365, in the Kitchen Small Appliances & Housewares category) generate an estimated 339 emergency-room visits every year in the United States, adding up to roughly 6,771 ER-treated injuries across the 20-year span from 2005 to 2024. PlainSafety derives a danger score of 37/100 for this category (low risk), combining raw injury volume, demographic reach, severity of outcome, and multi-year trend. The five-year trajectory shows that injury counts are rising by about 74% over the last five years, with the busiest year on record being 2023 (763 estimated ER visits) and the quietest 2019 (105 estimated visits).

The single most common ER diagnosis for heat pumps is internal injury to the head, accounting for approximately 437 visits across the 20-year NEISS window, followed by laceration to the head (411 cases). The 15-24 age group absorbs the largest share of injuries, about 1,119 cases over the NEISS window, and males appear slightly more often than the opposite sex in that cohort. Severity outcomes from the NEISS disposition field show that 7.6% of ER visits involving this product end in hospital admission or transfer.

Beyond the hospital-sampled NEISS projections, this page also aggregates 105 consumer incident reports filed directly on SaferProducts.gov, plus 20 anonymized ER narratives - together forming a layered picture of how heat pumps fail in real households. Every figure on this page comes from CPSC-published data: NEISS projects national estimates from a probability sample of about 100 U.S. hospital emergency departments, while SaferProducts.gov collects voluntary reports from consumers, manufacturers, and clinicians. The danger score, trend indicators, and demographic breakdowns update automatically when CPSC releases a new yearly NEISS file, which is why this page is dated 2024-12-31.

The submitter contacted the firm on July 18, 2018 to participate in the recall. She was told that the unit was included in recall # 18-113 and advised her that they would send out a technician to conduct the remedy repairs (verification # [REDACTED]). Approximately a week later she received the repair kit. On August 23, 2018 she contacted the firm again to follow up on the repair appointment and she was told that they would reach out to a local technician. On August 24, 2018 the unit stopped working. The submitter contacted the firm and she was told that a technician would come out the following week. The submitter said she had to buy a new unit because there is an elderly person in the home and the temperature was around the 90's. On August 29, 2018 the technician conducted the repair and noticed that the unit failed due to the defect described in the recall. The technician advised the submitter of the findings. The submitter claims that if the firm would have sent out a technician sooner, the unit would not have had an incident and she would not have been required to purchase another unit. The submitter has been communicating with [REDACTED] about a reimbursement but her request has been denied. September 21, 2018 Additional Information When the Tech came to install the recall part, the Tech ([REDACTED]) called me and I told her to forget installing part, as I was getting a new unit the next day. She wanted to go ahead, to avoid and responsibility on my part. When installing the recall part she called me again and said I needed to contact Goodman, as the recall part not replaced caused the unit to quit. My A/C service person quoted a cost of $519.00 to repair the existing unit, and it would take 7 to 10 days to receive the parts, he couldn't be without A/C that long. I talked to Gwen at Goodman, she refused to reimburse me for the new unit. I told her what my A/C person said about the cost, she the same as called him a liar, She

9/28/2018 · Incident, No Injury · LG Electronics, USA · Ohio

On 9-27-2018 at about 0348 hours I responded to [REDACTED] to investigate a fire in room [REDACTED]. Upon my investigation I found the fire originated in a wall HVAC unit. The fire was contained to the room of origin but significant smoke was on floors 3 through 12. I found that the HVAC unit malfunctioned igniting the combustibles where the heating elements were located. I spoke to the lone occupant of the unit. He told me he was chilled so he turned the unit to make it warmer when it started sparking and smoking. He called maintenance to report the unit. The unit then burst into flames. No one was injured.

9/20/2016 · Incident, No Injury · ALLSTYLE COIL COMPANY, L.P. · California

This cooling coil product from Allstyle Coil Company, INC., Houston, TX is designed to be installed on top of a forced air gas furnace. Allstyle coil Model AS60M264T Serial 7D16264S. This was installed on a Rheem furnace per install instructions. My Brother and me are in the HVAC business and he was the one discovering this. This coil has a plastic drain pan. This pan melted, cracked and was falling down onto the furnace heat exchanger. The photo's we have show the plastic pan bubbling and show the plastic got very hot and this heat made the plastic crack and the plastic could then fall out of place. This appears to be a fire hazard. I am sure from the look of the plastic is must have been gassing off and smoking. Anyway my brother replaced the pan with a new one. I have my thoughts on why this occurred. I believe their design is defective. Anyway I can e-mail the several photos we have of this incident. My cell phone [REDACTED]/ [REDACTED]

9/15/2017 · Incident, No Injury · Trane, American Standard and SchlageLink · South Carolina

The consumer stated that his issue is not with American Standard but with the Home Warranty Company.

9/10/2014 · Unspecified · WHIRLPOOL CORPORATION · Louisiana

A Central Air-conditioner condensing unit located at a house I own caught on fire which burned up all of the electronics and even destroyed the inside thermostat. We checked for lighting damage and there was none, neither the unit or the house was struck nor was their any power surge. The unit was replaced before I was able to get the model and serial numbers when I asked what happen to the unit I was told it was scrapped. The unit was only 2-3 years old so at first I was trying to get the manufacturer to honor the warranty, but I had no paperwork on the unit so I did not try to even contact the manufacturer. Then I thought there are probably other similar units out there and did some checking and found out that this unit was discontinued, it was a whirlpool. Was it discontinued because of a fault ? I am in the process of trying to find paperwork, I have the installer information and the distributor where the unit was bought. Contact me if that information is needed.

8/31/2020 · Incident, No Injury · ELECTROLUX/WHITE CONSOLIDATED · South Carolina

We installed a Frigidaire wall-mounted heat pump/AC in September 2013. The unit has worked well, up until today when it malfunctioned and exploded. The exterior of the unit ripped open, and the compressor was ejected into the yard. Frigidaire position is that since the unit is out of warranty, they aren’t going to do anything and don’t care what caused this dangerous malfunction.

8/26/2020 · Incident, No Injury · CLIMATE MASTER, INC. · Unspecified

Fire hazard. ClimateMaster model TES049 geothermal heat pump wiring shorted out during normal operation in the early morning of August 22, 2020. The wiring harness was positioned close to the copper refrigerant line going into the compressor. Electric sparks from the wiring arced against the copper refrigerant line causing a pinhole leak in the copper line. R410A refrigerant escaped and filled the garage, where the heat pump was located, with freon gas. Prior to this incident, the heat pump was experiencing false high pressure/high temperature faults in the water loop system causing the unit to shutdown prematurely. The house could have caught on fire while the occupants were sleeping. This unit needs to be recalled immediately.
