Keven explained our options and helped us with the right equipment for our needs. They were on time, came in on budget and cleaned up after the job. We highly recommend this company and feel confident you will be pleased with their work."

Air Conditioning questions, answered by experts

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 will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

Capacitors are the most frequent part of an HVAC system to experience failure. These components are crucial for starting the motors that power the fans and compressor, but over time, they may become worn or fail due to electrical surges or regular wear and tear. When capacitors malfunction, HVAC systems may experience decreased heating or cooling efficiency, or even total system failure. Replacement or maintenance of capacitors is a common requirement for the optimal functioning of HVAC systems.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.
