"Ralph looked over everything thoroughly and gave us an estimate. He came to do the repairs in less than a week. Ralph explained everything concisely and was happy to answer any questions. He is very knowledgeable, reliable, and careful. We have older units that were difficult to take apart and put back together; however, Ralph knew exactly what to do and handled the problem easily. He was very professional, careful of his surroundings, and cleaned up afterwards. He even helped us move some of the furniture back, which was unexpected and kind. Both my wife and I were impressed by his superior service. To top it off, Ralph is a great person! We are delighted with the wonderful job that he did. Highly recommend!"

"This was the worst experience i have ever had with a company. They came and damaged my house and kept us without AC for days. They admitted to the extensive damage and went weeks before attempting to repair it. The services were never fully completed and they were paid over 90% of the job. I disputed the last 10% and provided overwhelming evidence of their negligence. And after a year their last ditch effort was to send collections letters. Don't walk, RUN from this company. I will provide pics and my my experience to anyone who is planning on using this company. Used to be family owned and was amazing. Second they sold it went downhill fast."

Heating and Air Conditioning questions, answered by experts

If your AC refrigerant is low, you may notice that the unit takes longer than usual to cool your home or that your energy bills are higher. You may even feel a warm breeze coming from the vents when the AC refrigerant is low. Don’t attempt to check refrigerant levels yourself. Only certified AC repair pros should check and refill refrigerant.

Not if you have a standard unit. Because portable AC units actually work to dehumidify the room, you’ll likely need to drain the unit from time to time—but you won’t have to put water into it. There is, however, another type of air conditioner called a swamp cooler that requires water to operate. If you have a swamp cooler, you may need to fill a reservoir with water and potentially ice. But a swamp cooler is different from a standard portable AC unit.

The top reason to purchase an HVAC maintenance contract is the fact that it ensures you are detecting problems before they turn into expensive fixes. Secondly, this type of contract provides priority service, which is nice if it’s peak busy season. Finally, an HVAC maintenance contract provides discounts on parts and labor for repairs, which can save you a good amount of money if your unit breaks.

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.

There are several AC unit problems to troubleshoot, but luckily you can identify them by keeping a close eye on your system. Look out for the following signs that your AC needs repair:

  • Unusual noises during operation

  • AC unit blows warm air

  • AC unit doesn’t come on or turn off with temperature changes

  • Strange odors come through the vents

  • AC unit cycles on and off rapidly

  • Indoor air is more humid or less comfortable than usual

  • AC unit keeps tripping your breaker

  • Fan in the outdoor compressor doesn’t operate when the AC is on
