"Fontana Brothers responded to my Carrier Air Conditioner issue, Andre was very patience and seemed to be very knowledgeable. A solution involved the ordering of parts and which was handled quickly. The parts resolved my issues. It great to discover in this present world that excellent customer service is still provided."

"Had my new rental house ducts and dryer cleaned after i got ripped off by the $99 whole house duct cleaning gimmick. I called fresh air services,Darren answered my call right away his pricing was transparent and was less than other quotes I received. He showed up with his teammate and they went right to work cleaned my 10 ducts and dryer in about an hour. They actually take the vents down and send this brush hooked to their vacuum into the system. For a small fee i had them coat my return with this anti microbial coating made specifically for air conditioning and boy does it look so much better than the fiberglass duct board yellow.He even got on the roof and took a video to show me the vent was free of clogs. Their equipment was very impressive. I just returned to the home for the first time in about 3 weeks and the fresh smell from their sanitation fog is still detectable in the air. Donâ t get ripped off by the $99 whole house duct cleaning go with the pros at fresh air services"

Air Conditioning questions, answered by experts

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with. 

Indications of an HVAC problem include inconsistent heating or cooling throughout your home, unpredictable temperature changes, or inadequate air flow from vents. Abnormal sounds such as grinding, banging, or hissing, and unpleasant smells like mustiness or burning are also potential warning signs. A rise in energy costs without an increase in usage may also imply decreased efficiency. An HVAC system that frequently cycles on and off or cannot maintain a stable temperature is malfunctioning.

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.

It’s never a good idea to run your AC without a filter, even just for a night. The filter defends your HVAC system from the dust, dirt, debris, and other grime in your home. Without a filter, those contaminants are more likely to get inside your system and potentially damage it.
