"My wife and I appreciated the time Wayne took explaining what needed to be done and answered all of our questions prior to and during the installation. He and his crew did an excellent job installing the 2 high efficiency HVAC systems. Both systems are running well. I thank Wayne for his ongoing dialogue during the installation which gave us confidence in the quality of his workmanship. Even though the systems installed were an upgrade the cost was less than all the other installers that gave us price quotes for the project."

"The experience with Caesar and his A&C team was fantastic. Very competitive pricing for replacing my central air system (and the initial quote was also the final price). More importantly the work performed was very thorough - Caesar took his time to do the job the right way. Meticulous clean-up at the end of each day was also much appreciated. Overall great, highly-skilled professional who I would gladly reccomend to friends and family for their HVAC needs."

"They arrived promptly, entered the HVAC housing area and accessed the situation. I was glad to learn that my furnace was working fine and the smell of an electrical fire was gone. They changed the filter and suggested that I call them if the smell returned."

"Amro came over within the hour and looked at the pipe. I told him that I recently lost my job due to Covid and he worked with me on the price. He completed the job in minimal time and was meticulous about cleaning up after himself. As he was leaving, I asked him a question about my gas fireplace and he took the time to look at it, fix and and make sure it was safe to use. He even made me turn it on and off so he could watch that I was doing it correctly. I can't recommend him enough. He is now my plumber/HVAC guy."

"Mo is honestly a breath of fresh air. The quality of his work is second to none. He is brilliant. He works to find solutions. He does not sell you on anything but, instead, gives you options to make decisions. Mo is a wonderfully kind man. He is trustworthy with excellent communication. He always arrives on time. I could go on and on, but he really is a gem of a find. I highly recommend his company and would use him for anything HVAC related."

Heating and Air Conditioning questions, answered by experts

Split systems are the most common type of HVAC system. Split systems have two main units: an indoor one and an outdoor one. These units work together to pull in air, heat or cool it, and distribute it throughout your home. Other popular types of HVAC systems include hybrid systems and packaged heating and air systems.

You may never need an AC recharge if there are no leaks. However, if your AC unit has a leak that cannot be patched appropriately, you’ll need an AC recharge every time the freon level drops low enough that it disrupts your system—this could be once every two to three years. It all depends on the size and frequency of the leak.

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

You can adjust uneven airflow in your home by adjusting the dampers on the vents. However, if the temperature feels consistent throughout the home, don’t worry too much about uneven airflow. Generally speaking, larger rooms should receive more airflow than smaller rooms, especially if they only have one vent.
