4 Sons Mechanical Inc.

We contracted Freddie and 4 Sons to install Tosot Split AC Units and Condensers in our Multi-Family Home in Astoria. They did a fantastic job. They were quick, on time, and very communicative. They have also been very responsive to any questions we have had since the install. Highly Recommend!!!!

Freddy came to solve our problems with our Nest thermostat and boiler. We’re so grateful to have found such a professional and knowledgeable person. Although our heating system needs an upgrade and the thermostat needs to be replaced, he was able to correct some of the wiring issues and didn’t give up on trying to find a solution. We highly recommend Freddy.

We are really grateful to 4 Sons. Our AC system stopped working right before a heat wave (system was installed by another company). Initially they told us they wouldn’t be able to come for a few days due to a fully booked schedule, however when we mentioned we had a 4 month old baby, they made time the same day to come at the end of the day. They were able to diagnose the problem, patch the leak and get the system running perfectly. A big thanks to Freddy and his sons.

Freddy and his son came to service my ductless systems. I didn't realize how dirty they were. They had showed me before and after pictures plus showed me the units after the job was done. They did an amazing job. So glad I got this done before the heat hits. Will definitely be using them in the future.

4 Sons did an amazing job servicing my AC units. Extremely responsive and very thorough job. Very professional. Highly recommend for your AC needs.

Fred, and his crew where amazing. The installation was done perfectly and all units work perfect. I would highly recommend for your air conditioning needs.

Freddy was the most knowledgeable individual i have ever encountered with in the field of H.V.A.C. Hands down your first and last place you need for all of your heating and cooling needs. Thank you so much Fred.

Efficient, polite, answers all of my questions, and the repairs are done correctly. The last repair guy used created more problems. Freddy fixed all their mistakes.

Great service and clear communication on what was wrong with my home central AC unit. Freddy answered all my questions no matter how big or small.

They are the best
