"Of all the people I've had work on my home renovation in the last year, these guys were my favorite. Prompt, professional, honest, and reliable. When Duke came to give us the estimate, my 2 year old daughter wanted to give him a hug before he left which is unprecedented. That pretty much sealed the deal for us. They were also far and away the most reasonable quote we got. Even a friend quoted us $1500 more for less work. The installers were on time and knew their stuff. The install work is top notch as well. Everything in place and looks well put together. I highly recommend them to anyone looking for HVAC work."

"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."

"These guys are just excellent! I made a few mistakes before I got lucky to find New Millennium HVAC. They were professional from the beginning to the end. Jose did a thorough job, cleaning the dryer vent. It was not a straightforward issue and I was afraid that we’d have to open the wall to cure the blockage. However, Jose was able to fix it. He’s an experienced professional excellent at his job, trustworthy and overall great to deal with. I’m a happy customer for years now and will rely on these guys for any HVAC related issues."

"Almost a week ago, our 14yr. old fridge finally gave out and stopped cooling and freezing. We had to toss most our food, and we could not get a refrigerator repair technician until Dec. 20th. Who came to our rescue? Chill HVAC & Refrigeration. I called the office on Dec. 12th and the same day Kevin showed up and diagnosed the problem. After getting the necessary parts, he was back to the house on Dec.14 putting in a whole day of work removing all the worn our parts and replacing them in our large side by side fridge. Now with this new total parts replacement, you can say that we have a brand new refrigerator. Thank you, Kevin for the amazing proficient work. Thank you, Chill HVAC&Refrigeration for having such dedicated professionals. Next time something breaks, we know whom we will be calling."

Heating and Air Conditioning questions, answered by experts

Yes, a dehumidifier and air conditioner can be used simultaneously in a home. A dehumidifier can bolster an air conditioner’s efficiency. Typically, a dehumidifier is used when the air conditioner alone cannot keep a home’s humidity levels at a comfortable indoor humidity level, which should, ideally, be between 30% and 50%.

AC capacitors have a wide lifespan, ranging from five to 20 years, with an average of about 10 years. Many capacitors will last for the entire life of the air conditioning unit, and most homeowners only need to replace one once. A capacitor should only be replaced if an HVAC professional diagnoses a problem with it. Premature failure can be caused by overheating, power surges, or short circuits. You can help extend the life of your AC capacitor by scheduling regular AC maintenance each year.

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.

Many factors affect how much adding air conditioning will cost you, from the size of your home to the size, type, brand, and installation specifics of the system itself. Chances are, a new central air conditioning system for a 2,000-square-foot house will cost somewhere between $3,900 and $7,900 to install, with an average around $6,000

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.
