"Hudson Valley HVAC is simply the best! I have hired them for a number of jobs. From repairing burst boiler pipes from the cold. To upgrading the boiler diaphragm. Fixed some plumbing issues and most recently installed a nice RO (reverse osmosis) water 'filter' for clean drinkable water. They are honest, reliable and fairly priced. I would highly recommend them for anyone looking for quality service."

"Sync mechanical diagnosed and repaired our boiler in the same day, replacing a broken fuel pump for a great price. Boiler is working better than before and the house is warm again! They were highly responsive after listing our needs on Angi, were highly professional, and were also helpful in talking through some other potential work on our heating system without being pushy. Really friendly crew that does great work. We just bought our first home so it's a treat to find a solid team who we feel we can trust for the long haul. Highly recommend!!!"

"When something breaks that you have no experience with, you're doing more than just looking for someone that will fix it. You're putting your faith into someone to do the job and at the same time not take you for a ride for all you're worth. Mark was that professional for us when our water heater went. He was knowledgeable, skilled, and his rates were very reasonable compared to others. It was a pretty extensive job. Mark ended up installing a combination water heater and boiler unit to replace the broken system and our ancient boiler. He left our basement better than when he started. We definitely recommend him and will be returning to him for future projects."

"We had problems with another company. All Bases Covered cleaned and tuned up our boiler and heating system. We had a good experience. Based on our experience, I would hire them again and recommend them to others."
