“We recently had a new central air conditioning system installed by Alex Air & Heating Services, and the entire experience exceeded our expectations. The installation was clean and professional, and the crew treated our home with care. They also modified our ductwork so each floor can be controlled separately, which has made a huge difference for our family. Everything works perfectly, and our home has never been more comfortable. I would absolutely recommend Alex Air & Heating Services to friends and family.”

AC Installation
“We recently had a new central A/C system installed, and the team did an amazing job! They redesigned our ductwork and upgraded the system so our upstairs and downstairs can now be controlled separately with independent thermostats. This has made such a huge difference for our family. I live with my elderly mother, and she prefers a warmer temperature, while the rest of us like it cooler. Now everyone can set the temperature that's comfortable for them without affecting anyone else. The installation was professional, the crew was knowledgeable, and they paid great attention to detail. Everything works perfectly, and we're extremely happy with the results. I highly recommend them to anyone looking for quality HVAC work!”

AC Installation
“Our central AC wasn't keeping the house cool, especially during the afternoon. The technician arrived on time, found the issue quickly, and had everything working again the same day. He explained the problem clearly without trying to upsell anything. The airflow is much better now, and the house cools down like it should. Fair pricing, professional service, and a smooth experience from start to finish.”
