"The unit is very old and it's not worth fixing as it needs to be replaced. The technician was very knowledgeable and informed me of my options. I have been using Shavitz for years and they replaced my main HVAC unit a few years back. They always come through and make it happen. When other companies say no, they try and come up with solutions to help."

"Vinny came over to my home the same day to give an estimate as I needed to replace my exisiting humidifier. I already knew it wasn’t working and super old so best to replace it. He explained everything to me when looking at my furnace room. Explained the different size and efficiency of the various models I could use with the size of my home. Quick to schedule installation as well :) I will definitely use this company for future HVAC needs!"

"It went very well. Joe did such an excellent job in his initial meeting that we decided to go forward with him and his crew to install HVAC system for our 3 flat. He showed up on time every day and finished the project ahead of schedule. He was very professional, experienced and patient. I highly recommend him and his team for all your HVAC installation/upgrades. Thanks Joe!"

"I had a great experience with their HVAC services. They repaired my electrical baseboard heater quickly and made sure everything was working perfectly before leaving. The team was professional, punctual, and very knowledgeable. They also installed our new central A/C system smoothly with no issues at all. Communication was clear throughout the process, and the pricing was fair. Highly satisfied with the quality of work and customer service. I would definitely recommend them for any heating or cooling needs."

"In May of 2021, CR Mechanical replaced our HVAC equipment (furnace and AC), and installed a new air scrubber and an ecobee thermostat. We were very satisfied with their work (exceeded expectations), and Craig is an excellent installer (that was most important to us). The ecobee was defective out of the box, and he reinstalled our old thermostat and was back the next day (as promised) to install a replacement ecobee. Everything works great."

Heating and Air Conditioning questions, answered by experts

Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.

Yes, it's normal for air conditioners to leak tiny amounts of water due to condensation. Under normal circumstances, all excess moisture travels to the drain pan to be pumped through your system's drain line. You should call a technician to diagnose the issue if you're noticing frequent leaking or pooling. It's also important to investigate if your homeowners insurance can cover water damage.

The cost to repair an air conditioner averages around $350 to $450, but the price can range from $100 to over $3,000. The final cost depends on the type of air conditioner, the extent of the damage, and the specific parts that need replacement. For example, repairing a window AC unit typically costs between $100 and $250, while central air conditioner repairs can range from $300 to $3,000. A simple fix like replacing a dirty filter might only cost $10 to $50, but a major issue like a broken compressor could cost around $2,000 or more, potentially making it more cost-effective to replace the entire system. Due to the need for specialty tools and handling of refrigerants, repairs more complex than changing a filter are best left to a professional.

Your central A/C unit should be professionally serviced and inspected at least once a year to ensure it operates properly and efficiently. This is best done before the peak cooling season. A full-service inspection by a qualified pro will typically include checking safety components for issues like carbon monoxide leaks, verifying cooling components and coolant levels, and inspecting electrical parts like fuses and wiring. Regular servicing enhances efficiency, mitigates potential problems, and maintains optimal performance. Because AC systems contain hazardous refrigerant, professional handling is essential.
