Looks nice and neat and they took time to explain what they did and what to expect. I have rental property and Mike will be the 1st person I call in the future. 5-Stars all the way!"

"The plumber was courteous & competent. I wouldn't hesitate to call this company again if I needed help."

"They have replaced my water tank, water heater, and water pump and Iâ  ve hired them to replace my sewer line"

"Great job, done quickly, reasonable price. In and out in roughly 30 minutes. Install was a replacement faucet behind a sink so very tight work space. Not a lot more to say. Thank you!"

"After dealing with a large Capital Region company for 20 years; I am glad I made the switch to Veritas Heating and Cooling! I wanted to replace my aging Central A/C unit and furnace BEFORE unexpected major problems/expenses arose that would put me in a position where I would need to --rush-- into getting estimates/new equipment installed. I found Veritas Heating and Cooling through careful research on HomeAdvisor and Angies List. What finally convinced me to get an estimate from Veritas was a neighborhood recommendation I received while asking for an HVAC company referral through the -NextDoor- neighborhood social media website. I contacted several area companies and received estimates, but after meeting Adam I was convinced his company was the one I would go with. Adam is very professional and honest. He did not try to --upsell-- me with features and equipment that I did not need. He asked me key questions and recommended the Heil equipment level I needed based on my answers. Adam is a competent, experienced craftsman, and his prices are fair. His competency and experience were evident throughout the installation and equipment start up process. Adam was very efficient and he has an excellent work ethic. Adam was willing to work with me with the installation time frame as I was not ready to install for 4 months after signing my contract. Adam --locked in-- my pricing with a 50% deposit, and performed my installation as per my schedule (there was a 10% price hike coming at the beginning of 2019). Veritas Heating and Cooling is now my go-to HVAC Company! I would not hesitate to recommend them to anyone."

"Mike McGovern and his son Brian installed a Navian NPE-240S2 tankless water heater and removed the old 50 gallon tank. The installation required new vent piping. Mike considered several options for routing the pipes and made an extraordinary effort to implement the venting with a maximum of six elbows as specified by the manufacturer to assure adequate venting, away from windows, while still providing protection against rain. It has now been seven weeks and the new installation has performed flawlessly. I could not be more pleased with the work."

"They offer service scale clean out of the thankless water heater. I may contact them at a later time for this service."
