  • Why does my AC unit freeze up?

    Low refrigerant and poor airflow are two main reasons your unit may freeze up. Having your HVAC unit serviced regularly and changing your filter helps keep your unit working correctly.

  • How can I improve my indoor air quality?

    If you’re concerned about your home’s air quality, replace your HVAC system’s air filters or get a professional air quality system installed.

  • How do I find out if my unit is under warranty?

    Each HVAC unit has a serial number. Most manufacturers’ websites allow you to access the warranty information for your unit with the serial number.

  • Why is my unit taking forever to cool my house?

    If the issue occurs suddenly, it may point to problems such as a blocked filter, damaged ductwork or a refrigerant leak. If you have a recurring issue, but your system doesn’t need repair, it may not be configured appropriately for the size of your house.

  • My unit is making a weird noise. What does it mean?

    If you hear a rattling or banging sound inside your unit, the noise could mean a loose part. A hissing noise could indicate leaking refrigerant. Buzzing sounds may indicate an electrical issue. Seek professional advice if your unit isn’t making its normal hum.

  • Why is my shower pressure low?

    A clogged showerhead, valve settings, plumbing leaks or sediment in your hot water tank are all possible reasons for low water pressure in the shower.

  • Why does water come out of my faucet when the shower is on?

    The most common reason your faucet leaks water while the shower is on is a problem with the diverter. This valve controls water flow to your faucet or shower head.

  • Why is sewage coming out of the toilet?

    If your toilet isn’t flushing properly or you notice sewage backing up into the bowl, you may have a clog in your plumbing system. Check your other toilets and drains. If they are clear, you may have a small, local clog that needs to be fixed. If more than one drain or toilet has sewage, you may have a larger clog blocking your sewer line.

  • What do I do if my toilet leaks at the base?

    Check for loose bolts, deteriorating wax rings or a loose water supply line. During the summer, your toilet may also produce condensation leading to droplets of water on the base.

  • How do I get rid of odors coming from the garbage disposal?

    First, check your product manual. The manufacturer may have included recommendations like grinding ice with the blades. You can also use baking soda and vinegar or buy products specially made for cleaning disposals.

  • Can I prevent my pipes from freezing?

    Keeping your house above 55 degrees in the winter, letting your faucets drip slowly, opening cabinets and vanities, and insulating pipes can prevent your pipes from freezing.

  • What should I avoid putting in my sink?

    Even if you have a garbage disposal, there are certain foods you should not put in your sink. Rice, pasta, egg shells, coffee grounds, fats and oils will clog your pipes over time.

  • Have More Questions? Contact Bruni & Campisi

    If you have more plumbing or HVAC questions, or you have an issue you can’t seem to troubleshoot, Bruni & Campisi can help. Contact us with questions or schedule service in New York or Connecticut.

  • Why are multiple drains in my house clogged at the same time?

    When more than one drain backs up at once — or you hear gurgling from the toilet when you run the sink — the problem usually isn’t a simple clog. It points to a blockage in your main sewer line, which needs professional diagnosis fast to avoid backups and water damage. Bruni & Campisi offers camera inspections and drain services across Westchester, Putnam, Rockland, and Fairfield counties. Learn more about our drain services.

  • Are chemical drain cleaners safe to use?

    We don’t recommend them. Store-bought drain cleaners can corrode older pipes, damage seals, and rarely clear the full clog — meaning the problem comes back. Professional drain cleaning removes the blockage completely and protects your plumbing long-term.

Owner came right away despite it being nightmarishly cold & he was very busy but he explained everything carefully to me & did NOT notice that I was a single mom & start mansplaining to me with technical terms that I can’t understand & didn’t charge me a fortune. A true pleasure!

Emilio was very detailed oriented and focused on his work. He did a very clean and comprehensive installation of our indirect water heating system. His setup was organized and clean up was well executed. Emilio also explained the process and the how the system worked very smoothly and easily. Derek, who came to give an estimate arrived promptly and was able to explain the quality of work needed for such an installation. Emilio executed this process very well. I needed the work done the same day since we did not have any hot water and heater was offline also. The team at Bruno and Campisi was empathetic to my feelings and my family and was able to get the job completed on the same day. Our family slept soundly after staying up part of the previous night because the water heater leaked water all over the basement. Oh yes, Emilio and Derek even designed the system where excess water would go right into the drain so major water damage issues could be mitigated. Thank you to the wonderful team at Bruno and Campisi.

Jason R arrived promptly and did a great job walking me through the system in my house. As a new owner of the house, he was thorough in his assessment and noted a couple items for repair, without being pushy. We plan contact the company again to address the fixes Jason identified.

Chris Monge showed up on a Saturday afternoon and worked hard to finish the job that installers of our new boiler did not address. Chris figured out what needed to be done and the released the air in every radiator in our house.
