How Your Disposal Repair Visit Works

Disposal repair is short work when it’s diagnosed correctly the first time.

Disposals usually fail in one of six common ways, and the visit identifies which category you’re in before any parts come off the truck.

You contact us by phone or online. Our team gathers details about your disposal: the brand and model if you know it, what symptom you’re seeing, and how long it’s been going on.

Your licensed plumber inspects the disposal, the mounting, the wiring connection, and the drain path. Pricing comes to you in writing before any work starts.

Your plumber completes the repair, tests the unit through a full operating cycle, and confirms the drain flows properly.

We have used Princeton Air twice for our HVAC and once for plumbing. Each time, the technician was courteous and professional, and the issues were resolved. We recommend Princeton Air!
Tech from Princeton Air (Brian Hassan) showed up on time and performed yearly maintenance on our Kohler Generator. Very professional and courteous technician. Thanks for taking care of our generator like it was your own.

Just had a tech Cruise Rodriguez trouble shoot a minor wiring issue on our new Carrier furnace which was installed this week. As we were installing a new thermostat WiFi Honeywell there was a mismatch which Cruise located and rewired. System seems to be up and running with new thermostat.
Thank you Cruise for your expert help in resolving this issue.
Dominic is very professional and clearly knows what he is doing .
Jonathon and Louis were professional and neat! They Answered all my questions
Dominic was extremely pleasant, professional, and thorough,. He was also quite efficient. He quickly diagnosed the situation and was able to correct it. He also took the time to patiently explain my thermostat to me. Then he signed me up as a member. So heโ€™s a pretty good sales guy too!
However, I then set up an appointment for maintenance and twice Princeton Air canceled me. Iโ€™m now set up for maintenance the end of June. And thatโ€™s after they tried to set me up the end of July and I complained.And this is after Dominic signed me up as a member. Thereโ€™s something very wrong with their business model and I do not consider this good customer service. I will likely have to look for a different serviceโ€ฆ. something more responsive.
I had a great experience with Princeton Air. I had an issue with a part of my healer leaking. Within an hour of calling about this problem, Dylan, the technician, arrived at my house. He soon identified the problem. The next day 3 technicians came back and replaced the faulty part.
Repair went smoothly and efficiently, very satisfied.
One of the worries anyone with a new system would have is if it turns bad, how can it be cared of. Princeton Air answers that question. They responded quickly, sent technicians to look at the issue, and found the proper solution for you. The coordinator at the office is very nice; she would answer my email, and call me back about it even it was on weekends. Such a call is important because it tells you that you are not left out! Wish they will continue the good service. Feng.
Always appreciative of service from Princeton Air. This time it was to install a new quick-Connect hose for the gas grill. Friendly, knowledgeable, and efficient. Thank you for the great service.
Knowledgeable, Pleasant, provided insight for me to make an informed decision that best meets my needs
Technician was knowledgeable. He was able to find the issue quickly and fix the problem without issue.
Very good service. Cruise did a terrific job resolving our problem and was a pleasure to speak with.
I am so thankful to Princeton Air for sending to me your very best technician, Dominic M, on April 2 to do the maintenance for my air conditioner! Dominic is very professional, knowledgeable and talented. He was so thorough and he explained everything to me as he did it in a way to be sure I could understand. He explained what was working well and what problems needed to be addressed, then came out 2 days later and completed the repairs! I'm so thankful and I would highly recommend Dominic M!!
Brian Hassan the tech assigned to us was excellent. He was professional courteous and knowledgeable. I will ask for him again if we need anything. I will be using Princeton Air for electrical HVAC and plumbing

Thanks Brian and Princeton

Ryan was here yesterday and did a great job. Unfortunately we need a new HVAC system but Ryan did everything he could to get us back in service. Thanks Ryan you are great

Dominic M was great. He was patient and set our new thermostat for is. It is a new type of thermostat that came with our new heat pump system and we didnโ€™t know how to use it. Dominic really took his time and set it for us he was understanding and we appreciated his effort.

Robert D was here to check a switch and once again he was great. Professional expedient and overall very accommodating .
Tom did a great job of identifying and repairing a pinhole leak in our minisplit AC system. The cost was high, but the amount of labor and material justified it – these things ain't cheap! Tom is a very personable and knowledgeable tech.
Technician arrived promptly and diagnosed the problem with our air-conditioning as being the blower that was not operating properly. Karume advised us of the ordering process, quoted us a price for the part as well as who to contact at Princeton Air Parts Dept on Monday for more information on how long it would take for the part to come in and be installed. Karume is an exemplary employee and is always welcome to make a service call at our house.

Garbage Disposal Problems Our Plumbers Resolve

Disposals jam, hum, leak, or go silent, and each of those symptoms points to a different cause.

Princeton Air’s licensed plumbers have repaired every common disposal issue.

You flip the switch and hear the motor humming while the unit doesn’t actually run. That symptom almost always means the grinding plate is jammed against something hard. A jam can sometimes be cleared by unjamming the disposal manually, but repeated jamming points to motor stress that may require replacement.

You flip the switch and nothing happens. Silent disposals trace to a tripped reset button on the unit, a tripped circuit breaker, a wiring connection failure, or a motor that has finally burned out. Your plumber diagnoses the specific cause rather than replacing the whole unit when it’s not needed.

You see water in the cabinet below the unit. Disposal leaks come from three specific places: the top sink flange, the dishwasher drain connection, or the drain outlet at the bottom of the unit. Leaks from the top can be repaired; leaks from the body of the disposal usually mean replacement is necessary.

You notice an odor coming from the sink area even when the disposal is off. Odors come from food buildup on the grinding chamber walls or in the baffle at the top of the unit. A thorough cleaning usually resolves it, though some units accumulate buildup that requires more attention.

You find water backing up into the sink when the disposal runs. Slow drainage from a disposal usually traces to a clog in the drain line just beyond the unit, sometimes combined with food buildup in the disposal itself. Your plumber clears the line and restores normal flow.

You hear grinding, rattling, or metal sounds that weren’t there before. Unusual noises often mean a foreign object (silverware, a bottle cap, a piece of hard debris) inside the grinding chamber. Your plumber removes the obstruction and checks whether the grinding components have been damaged.

Why Princeton Air for Garbage Disposal Repair

Disposal work sits at the intersection of plumbing and electrical, and you want a team comfortable with both.

Princeton Air has served kitchens throughout Mercer County for decades.

Your disposal repair is handled by a licensed plumber who works on disposals regularly and knows the common failure modes for each major brand.

Your truck arrives prepared with the mounting hardware, gaskets, and common parts that most disposal repairs need, along with access to replacement units for situations where a repair doesn’t make sense.

Your kitchen is kept clean throughout the service, with the cabinet protected and debris handled properly.

Princeton Air handles plumbing and electrical together, which matters on disposals because the electrical supply is often part of the diagnostic.

Older disposals with motor failures often aren’t worth repairing compared to replacement. Your plumber walks through the honest economics of your specific situation.

Frequently Asked Questions

What do I do if my disposal is humming but not grinding?

Turn the unit off immediately to prevent motor damage. The most common cause is a jam you may be able to clear using the hex key slot on the bottom of the disposal. If the unit still doesn’t run after you clear the jam and press the reset button, a plumber can diagnose the motor and wiring.

How long do garbage disposals last?

A typical residential disposal runs 8 to 15 years, depending on use patterns and whether the household puts hard or fibrous items through it. Higher-horsepower units tend to last longer because they struggle less with routine use.

Can I put anything down my disposal?

No. Bones, fruit pits, fibrous vegetables like celery and corn husks, grease, pasta, and potato peels all cause problems. Small amounts of softer food waste work well; anything that stresses the motor or clogs the drain should go in the trash.

Why does my disposal have a bad smell?

Food residue accumulates on the walls of the grinding chamber and the baffle above it. Running cold water while grinding citrus peels, or using specific disposal cleaning products, addresses the buildup. A plumber can perform a deeper cleaning if the odor persists.

Do I need a plumber to install a new disposal?

It’s recommended because the install involves plumbing connections (sink flange, drain line, dishwasher connection) and electrical work (hardwired or plug-in power supply). Mistakes in either can produce leaks or electrical issues. A professional install is typically inexpensive and prevents later problems.
