“Jason did HVAC duct cleaniing for me. He did great job! Very professioanal, friendly, attetive team. Definetely recommend.“

“Matt is reliable, honest, respectful, trustworthy and charges fair prices for services rendered. It took many years, and several unethical, unreliable and untrustworthy plumbers who charged inflated prices for sub-par work. My wife and I highly recommend Hatfield Brothers.“

“Our AC turned off yesterday and even on a Sunday they answered our call and scheduled us an appointment for the following day! They service central AC, which is rare. Super friendly, very insightful, and reasonable pricing! We'll definitely be using them again in the future! Choose Cal's for you air conditioning needs!“

“Scott was very quick to respond when our heating system fan motor just stopped working in the middle of winter. He had Mike come and look at it same day, installed shortly afterwards. Scott gaves us a such a great deal! Mike was friendly, efficient and cleaned up everything afterwards. Would highly recommend S&E Cataldi for your heating and/or A/C needs!“

“I have used Mike for at least 8 years. Boiler, Furnace, Bathroom Plumbing, Pool Heater install, etc. Top notch every time“

“They came called head of time and arrived on time and fixed my faucet in the utility room that was leaking, cleaned up all the mess, then went outside and installed a new faucet outside.they asked if there was anything else I would need their services..I would recommend them if anyone needs plumbing done..Services: Faucet repair“

“I originally called because I thought I had a sewer gas leak. Just arrived on time and gave me a 25 minute heads up prior to his arrival. It took him about 35 or 40 minutes To diagnose the problem which was actually a leaky propane fitting. Justin was courteous and professional. He explained to me the process from step one all the way to the end.“

“Yesterday 7/26 Christian and Tyler came and recharged our HVAC units and installed a new water pump. They were incredibly professional, personable and kind. We had to rebuild a floor to put the new pump on and they were so patient with us. They also did a really great job. We’ve had quite a few people in the last 2 years come out and look at our HVAC system and none of them have been able to fix or fully identify the problem, but they were! We’re really grateful for them, now our HVAC is working better than ever. Thank you guys!“

“Great customer service & the quality of work was great. The 3rd time we have used them.“
