"As a senior citizen I have dealt with many contractors/tradespeople in my lifetime and a few of them have disappointed me but overall have been satisfied and then there are a few in my "TOP 10 LIST" who were EXCEPTIONAL & OUTSTANDING which is rare these days. So, Craig at C&A Mechanical and his team are indeed EXCEPTIONAL!!! Craig the owner personally came to my home to review the damage caused by a faulty tank as I had no heat or hot water and promised it would be fixed the next day! As promised his team member Alex was promptly at my home the very next morning! Also, his quote was "Fair & Reasonable" and at the end of the job it was LESS $$$ then the quote because it required less time than estimated. NOBODY does that these days! So I HIGHLY recommend C & A Mechanical for your HVAC needs! Bobby A"

"I am not a review writer at all, however, I felt it only fair to write a review for Eric and Just Rite HVAC after a wonderful experience. This company and Eric the owner are, in a word, the BEST! I needed main floorâ s central AC replaced. A friend recommended me to Eric. I texted him and he responded with a few hours. setting up an appointment was fast and easy. Eric was knowledgeable and timely. My job was extremely difficult based on the location of my air handler and there was a high chance the ceiling would need to be opened for access. When Eric arrived for the job he inspected further and said he was going to try not to have to open the ceiling for access. He and his crew went well beyond what anybody else would have done and meticulously dismantled the old air handler piece by piece. It was time consuming, difficult and energy consuming. But they were able to do and saved me from having a gaping hole in my ceiling. They did an excellent job setting up the new air handler in the same location and even fixed errors the previous installer had made! The entire crew were highly professional, courteous and clean. They put down drop cloths everywhere and cleaned up everything when they were done. I highly, highly, and without reservation, recommend Eric and Just Rite HVAC and will tell anybody I know about them."

"This was the worst experience i have ever had with a company. They came and damaged my house and kept us without AC for days. They admitted to the extensive damage and went weeks before attempting to repair it. The services were never fully completed and they were paid over 90% of the job. I disputed the last 10% and provided overwhelming evidence of their negligence. And after a year their last ditch effort was to send collections letters. Don't walk, RUN from this company. I will provide pics and my my experience to anyone who is planning on using this company. Used to be family owned and was amazing. Second they sold it went downhill fast."

FAQs for central humidifier installation and replacement projects in Syosset, NY

Aim for indoor humidity between 30% and 50%, with the sweet spot around 45%. That range keeps mold, dust mites, and musty odors in check while protecting drywall and woodwork. Staying in the zone also helps your HVAC system run more efficiently and supports healthier air for you and your family year-round, during hot summers and cold winter months.

With routine filter changes and coil cleanings, most whole-house units run for eight to 15 years. Heavy use, poor air quality, or bargain-bin equipment can shorten that span, while a well-maintained, high-quality model often makes it to the upper end of the range. Ask your installer about recommended service intervals to get the most mileage from your investment.

It depends on your climate. Homes in cold, dry regions can often shut the dehumidifier off once winter sets in. If you live in a warm, humid area—or your house tends to trap moisture—you may need to keep it running year-round. Use a simple hygrometer: if readings stay below 50%, give the unit a rest. Just remember to restart it when humidity climbs again to avoid mold and condensation.

Dry air feels cooler, so your AC doesn’t have to work as hard. By stripping out excess moisture, the dehumidifier lets you raise the thermostat a few degrees without losing comfort. A shorter AC runtime reduces electricity use and can shave a noticeable amount off your summer power bill. Energy-efficient models further enhance those savings.

If your home is under about 2,000 square feet, a well-placed portable unit can handle the load. Just remember they’re less efficient and need hands-on upkeep—think emptying tanks and cleaning filters. If you prefer set-and-forget convenience or plan to expand your living space, a whole-house model still offers better long-term comfort and lower energy use per square foot.
