"Very prompt to respond to my call. Service person very pleasant and knowledgeable. Reviewed in detail what he thought problem was. Offered to have me sign up for regular service visits twice a year which made cost of this visit nothing so I agreed. Said they would order part he thought I needed and have it available if required which I appreciated. He wrote some descriptions of the HVAC system in his notes which described ducts as in " poor condition " but didn't mention that to me. I thought he should have. Will use again."

"We had a totally broken HVAC system in our 30 year old house. They came in and fixed it in two days. The guys were very friendly and answered our questions. Our original salesperson was knowledgeable and respectful considering the state of our equipment at that time. Now we have heat for the rest of the Winter and AC for next year. Thank you!"

"Albert Nahman PHC installed new AC and Furnace for my house. I like them for several reasons -- 1. At first Tom explained in detail what equipment I need and how they work, and gave me a reasonable and detailed quote at end of the visit. 2. They offer interest free finance. 3. I got free upgrade for furnace when the original quoted is not available. 4. Their installer did good job, and cleaned up afterward. I highly recommend this company."

"Green Core HVAC was awesome to work with! The team did a great job helping us pick the perfect AC unit for our home. They showed up on time, got the new AC installed quickly, and left the place spotless. Our house is cooler and more comfortable than it’s ever been. You can tell these guys really care about doing a great job. I’d 100% recommend Green Core to anyone needing AC work. Super professional, super friendly, and they really know what they’re doing!"

Heating and Air Conditioning questions, answered by experts

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

Unfortunately, a freon leak will persist even when your AC unit is off. The freon in the AC unit is under pressure no matter the status of the system, so it will continue to drip through the leak even when you shut off the entire unit. It will continue to leak freon until it’s completely empty.

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

No. Evaporator coils are designed to work with specific refrigerant types, and they are rated by what kinds of refrigerant they use. It’s indicated with an “R” code. It’s important to match your evaporator coil and refrigerant or your system will not work properly. An AC technician can tell you what type of refrigerant your system needs and what evaporator coils will work with it.
