Customer Reviews
“The entire experience from the initial estimate through installation was professional, easy, efficient, and met our needs for ductless heating and air conditioning.”
-Mardi
“I am extremely happy with the Carini crew. Family might be a better word than crew. I’d like to recognize Geo who took the lead on my day of install. I wish I could remember his co-installer’s name. Smooth sailing for my split duct a/c on the top floor of my home where it gets hottest.”
-Bradley W.
“All the employees involved with our project went above and beyond their job descriptions. Excellent install! The guys were very personable, helpful and knowledgeable. Clean and tidy. Highly recommend this company! One of the key things was pre-install, Carlos spent a lot of time explaining the the best design and equipment options for our home.”
-Teresa A.
“I recently had my HVAC replaced. Many thanks to Carini Home Services for an outstanding job. I appreciated the teamwork from Kathy in the front office; John for estimate; Gio & Jesse for installation; Anthony for oversight; and Diana closing the loop in billing – very efficient; impeccable communication.
Covid protocols were followed, and all that came to my home were respectful. John listened to my requirements and didn’t muddy up the estimate with extras I didn’t ask for (or need). He asked the right questions and obviously did his homework on the homes in my neighborhood. Gio & Jesse are the ideal installation team.
They arrived early both days; kept me informed throughout the install; cleaned up work areas; and maintained a positive attitude the entire time. I really felt this crew truly cared and my satisfaction was a high priority. They weren’t being nice just to be nice. Thanks again, Carini Home Services!”
