"I had a great experience with Nate. He was extremely knowledgeable about A/C systems and was far more well-versed than many other companies in the area. He took the time to explain everything clearly, answer my questions, and make sure I understood the issue and solution. Nate was also very friendly, professional, and informative throughout the entire visit. I truly appreciated his expertise and excellent customer service. I would highly recommend Nate to anyone needing HVAC service."

"Patsy Cicala has so much knowledge and experience and was able to dismantle the mess made by the plumbers and correctly configure and install the filter system. It is working perfectly now and we are enjoying pure filtered water. Mr. Cicala really saved the day! In addition to being experienced and competent, he is reliable, respectful and pleasant to work with. I definitely recommend him and will contact him again for any projects or services needed in the future."

Heating and Air Conditioning questions, answered by experts

You should know the main components of an air conditioner: the condenser coils, evaporator coils, drip pan, AC filter, ducts, and refrigerant. Each part plays a key role in the performance and safety of your AC system. When tracking the source of AC issues or odors, it helps to know where to look. Your outdoor unit houses your condenser coils, fan, and compressor. Your indoor unit houses your evaporator coils, drain lines, and filter, and it connects to your ductwork. 

While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.

Some things that shorten your AC’s lifespan include:

  • Extreme outdoor conditions, like high humidity or extensive salt spray 

  • Improper installation

  • Extended run times, either by the unit being too small or the thermostat setting too low

  • Not performing required maintenance

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).

Yes, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.
