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.

The Tech arrived on time, quickly figured out the problem with my AC and fixed within an hour. Pricing reasonable and professional service. Highly recommend!
Cruise was great! He addressed our AC issue quickly and professionally.
Weโ€™ve always been satisfied with McAllister and our recent experience since the merger has not changed that. We needed a new condenser for the A/C and they had a cost effective solution and were able to install it quickly.
Very efficient and on time
Princeton Air condition was extraordinary!! I received a very fair quote immediately after Inspection of my HVAC systemby their talented technician. Their technicians were prompts, professional, and polite. They installed a new system with precision and followed up Professionally. Totally proud to work with Princeton.!!
Ryan G came by and provide tips and recommendations so thorough and with full clarity that I believe will benefit in the long haul. Because of this, I was confident to re-sign up for their maintenance program. He was a true professional who is highly knowledgeable and enthusiastic with the work that he is called to do.
Jose and Corey were a great team and genuinely seemed to care about solving our issues.
I had A/C installed in May, but waited to write a review to see how effective the units can be once it's hot out. Now that I've gone through a couple high temperature days where I turned the mini splits on, I can post a review that I am completely satisfied with the installation by Princeton Air Conditioning and the ease of usage of units. I also will add that it was a pleasure to have Mike C. and Christian J. on the job; they, along with the crews that were on site over the course of the two days, were professional, communicative and upfront. I'd recommend this company to anyone looking for services.
Professional and friendly staff
Air conditioning wasn't working and they came out and got it fixed within a day. Ryan did a great job making sure everything was up and running quickly.
The job was done smoothly and efficiently and right on time
Ryan G got our old air conditioner working again quickly during a bad heat wave and, when we were ready, he explained all our options very well and laid the groundwork to make it easy for us to have installed a new air conditioner. Plus he rescued our cat three times when our cat tried to get out through the garage. He was very kind to all our pets and to us. Thank you, Ryan G!
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.
Tech (Alex) was on time, courteous, very professional. He let me know that, because of my contract w/McCallister, I would have no extra payment for the part needed.
The repair man, Dominic came out this morning to inspect our AC system. He was extremely knowledgeable, incredibly kind, and explained things very well. I work in construction and can tell you that Dominic is one of the best Iโ€™ve seen in years. Princeton air is very lucky to have him as an employee as he is SUCH AN ASSET to your company.

I also want to give a special thanks to Leah the customer service representative I spoke to. Also extremely kind and helpful. I have had the worst two weeks of my life and two strangers taking the time to kind made my heart smile. Thanks again Leah and Dominic. Chuck our Project Manager has been very kind and knowledgeable through this process as well. I am grateful for the people who work here as they made this pretty easy. Thank you all so much.
Latrell Romulus from Princeton Air did a great job of making sure my AC units were working properly. He was thorough and knowledgeable, and communicated potential areas of concern in a very clear manner.
Great job ! Very knowledgeable and informative. He made sure I was aware of any issues and explained it thoroughly! I look forward to having him again !!

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.
