"Sila installed a new Lennox HVAC system 2 years ago and when there was a leak today they showed up within hours! Not like some places that would have many excuses and complain about Fri being too busy. Their Tech Calverton is a special tech, knowledgeable, polite and willing to go the extra mile. Not only did he fix the leaking problem he took his time to adjust dampers to ensure all rooms are toasty! This has always been a problem for us and not fixed until now. It takes a patient problem solving tech to make a happy customer! A special thanks to the service manager ,Doug Bines , who always seems to help when needed."

"We are extremely satisfied with the experience we had with Dario. Tony gave us a great estimate for a complicated job. He also gave us his honest advice about what to do and not to do. Glad we listened to him. He spent the time to figure out how to make something work even though it didn't look likely. The team was professional and friendly. We will definitely call them back for our future HVAC projects."

Heating and Air Conditioning questions, answered by experts

The $5,000 rule for HVAC systems helps homeowners decide whether to repair or replace an AC or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it’s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system.

To lower humidity quickly, run a dehumidifier or your home's air conditioner or turn on exhaust fans to extract moisture. These methods can quickly and effectively bring your home's humidity levels to a comfortable condition. However, you should consistently practice humidity-reducing tasks to maintain proper indoor humidity levels.

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy 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.

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.
