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.

Responsive, knowledgeable, dependable, & honest. Thank you for getting out heat up & running!

Update:10/12/18
Chris S got the heat last year and remembered when he arrived today, asked if it had a problem since. He came back to do a PM on the heater and while he was waiting for me to arrive, he opened up the air conditioner to inspect it and saw the coils were filthy. Took out his hose and cleaned them. Then when done, did the heater PM and then โ€œsaid I just want to verify that ringing noise went away. Your house will cool much faster now!โ€ I really like what Princeton air offers, quality and care, diagnose and fix. Not rushing to get to the next job. Theyโ€™re so good I got the year round service plan.

Maurice is fantastic.
Prompt and knowledgeable. Great technician.
There was an urgent need for a mold problem to be handled in a bathroom. They quickly identified the problem, tested the seriousness, and took care of it – in a very timely fashion. They communicated with me all along the way so I could fully comprehend what was going on. All the people were very knowledgeable, pleasant and accommodating. My experience with them was excellent, and I would highly recommend them.
Eric M. was prompt, professional, courteous and quite helpful. I become a better consumer when I understand the problem & possible solutions. Eric was willing to answer my questions and made me feel secure that he would follow up to help fix our problem.

Notice a problem with the humidity in my home, called and got a service appointment in the same day. Will D came out and sure enough, confirmed there was a problem, explained what exactly was happening, why it was happening and how to check that it was working correctly. His demeanor was pleasant, he was professional and seemed to be quite knowledge!

Maurice Gaines who cleaned and serviced my air conditioner was fantastic! He was fast, respectful and very fast with the repairs.

He made me feel like I was getting the full respect and honesty I so needed for something so important and really appreciated the time he took to explain every and answer all my millions of questions. Also Princeton Air communications were fast and accurate , leaving no question unanswered as to timing and confirmation of appointment. Iโ€™m so happy with their staff and with Maurice- heโ€™s a gem!
Thank you!
The young man who came out to fulfill our annual service contract was extremely professional and was very thorough. Although he told us we needed a new ac unit I felt confident that he knew what he was talking about and took the right amount of time in order to make his recommendation. I want him back every year. Unfortunately I forgot his name because Iโ€™m old.

He then had Ricky call us with replacement ac unit recommendations. He was just as professional. He then took the time to visit our condo, take measurements himself and then made recommendations on what size unit to purchase. I really feel he saved us money. He was amazing.

We then were contacted by a gentleman named Steve who was a manager in the service and installation department. Itโ€™s hard to believe but he was just as good as the first two representatives and was an absolute pleasure to work with. He was a true professional and a real asset to your organization. I will always use your company if I can work with this team. Keep up the great work. Thanks for allowing me to spend $8,000.its hard to believe I didnโ€™t even get other quotes because I was so happy with your team.

Recently Princeton Air did a routine maintenance check on our HVAC UNIT. The technician was Dominic McGinley. I must say Mr. McGinley was outstanding. After performing the maintenance and evaluation, he sat down with us and explained his findings in precise detail. He has also taken pictures of everything he found. Dominic was a pleasure with whom to interact. He was professional, friendly, and extremely knowledgeable. He explained everything in terms that we could definitely understand. He is one of the finest technicians that has ever performed preventative maintenance on our equipment. In my estimation he has all of attributes of a first rate Service Technician. Hopefully Princeton Air just what a valuable asset he is for the company. I certainly hope to interact with him many times in the future.
We recently used Princeton Air to install a new heater. They gave us lots of options, explained each one thoroughly, they arrived promptly on installation day and did a great job. The price was the lowest of three companies I contacted for estimates. Five stars!
Always professional and informative.
We just had our A/C serviced by tech Dominic McGinley who performed a thorough spring maintenance. Dominic was very friendly and courteous. He responded in detail to all my questions spending sufficient time with me.
We had valve and service line repairs from Germaine and Bradley, as well as a toilet replacement. They were great!
Julian found an issue with the ac and resolved it. Explained what the component does that needed replacement.

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.
