"It went amazing my kids and I have so many allergies specially in this season and it’s so hard when we can’t even feel good at home because of the dust in the air conditioning duct, I have been paying for many services with different companies and it just worked for few weeks until I hired this company and their work exceeded my expectations. Highly recommended. Thank you for the services"

"Joe was fantastic. He responded quickly to my inquiry, stayed in touch prior to the repair visit, arrived promptly and quickly resolved the problem with my central AC. His fee was very fair. Previously another HVAC company (not from Home Advisor) told me the unit was unrepairable and needed to be replaced. I highly recommend Joeâ  s company All-in-One for your HVAC, plumbing and electrical service."

"Although their estimate was a little bit higher than other companies T. Webber answered my questions thoroughly and were committed to doing everything above board and according to code. Since I have a strict building inspector this was very important to me. The sales person, the ACCA, the supervisor, the HVAC techs, the electricians, and the office personnel were polite, professional, top notch at their jobs, and made the entire process so much better. They dealt with the building inspector for me, filed the application and several technical reports as required, and took care of every aspect of the job. I recommend this company highly for their precision and attention to detail."

Heating and Air Conditioning questions, answered by experts

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Air conditioners and dehumidifiers are actually quite similar, though they perform different jobs. Dehumidifiers reduce moisture in the air, while air conditioners work to cool the home. A good central AC unit will naturally perform a certain level of dehumidification due to its design, but it will not be able to handle excessive levels of moisture.

The cost to add Freon to an AC ranges from $100 to $350. It can increase up to $600 for large AC units requiring much more coolant. The cost also depends on how much refrigerant your unit needs. If only a small amount of Freon leaked out, your cost would be on the lower side. A complete replacement of all the required refrigerant can get expensive.

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.

You will only need to refill your AC with refrigerant if it has a leak. Otherwise, a modern, well-maintained AC will most likely never need a recharge. You may notice a leak in an older system if your bills are higher, you hear a hissing sound, or if the air is blowing out hot.
