"There was no coolant in the unit so that's why it wasn't working. That's why no cool air was coming out of it. I had just purchased my home and I had just moved in and when it got warm, I had started using the air conditioning. I don't know who's responsibility but he was able to put coolant in and it's been fine. That's all I can tell you. It was covered by the insurance company. I did have to pay a little bit but I can't remember exactly. I would have to look it up in my records. He was super. He was just super and I would use him again. I might use him for my routine maintenance just to make sure everything is running properly before anything happens. It took less than an hour. I had a problem with the air conditioning and he contacted me through the insurance company and I was very pleased with the service. As a matter of fact, the agent who had sold the property to me was here because we were trying to work out the insurance details. He actually asked for his card, he asked for Duke's card because he really liked the way he handled the whole service call. So, he probably will use him again. I can't speak for him but he was really great."

"My mother's house had air conditioning that was improperly installed so it wasn't really cooling anything but the bill was still running pretty high. So basically there was a leak in the duct. I would use them again for air conditioning."

"They responded very quick and they found the problem. The part required was expensive and due to the age of the furnace I decided to purchase a new high efficent furnace. The price was fair and they installed it the next morning."

"The crew from Albert Nahman did a great job from start to finish. The project was to replace the original ductwork in our 60 year old house. Tom provided excellent advice for the estimate then Bryan’s crew did the job, 2 days, within a week of my acceptance of the proposal. Great work."

Air Conditioning questions, answered by experts

If you’re shopping around for a rooftop AC unit, you may hear them referred to as “package units.” That’s because rooftop AC systems are all-in-one heating and cooling units that connect directly to your home’s ductwork. If your AC repair pro references a package unit, they are referring to the system on your roof.

Yesh, heat pumps can easily cool homes when the weather reaches over 100 degrees Fahrenheit, just as powerful air conditioners can. The key is sizing the heat pump correctly for the size of your home and your climate. A local heat  pump professional can help you determine the right size and type for your home.

When your HVAC system is loud, a few different causes are possible. If you have loose connections or bolts in the hardware, they can rattle as the system runs and vibrates. If you have an extremely dirty furnace filter, it could cause the system to generate noise. More commonly, an excessively loud HVAC system indicates a malfunction in the system. You may have a blower motor that is close to failing or a compressor that is breaking down. These issues require an immediate inspection.

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.

The cost to replace an AC evaporator coil is typically between $600 and $2,500, with an average cost around $1,300 to $1,350. The price of the coil itself can range from $550 to $1,100, depending on the brand, size, and style, with professional labor adding around $700. Replacing a condenser coil is generally less expensive, costing about $800. Because this repair involves handling refrigerants, it requires a licensed AC professional. Regular inspections, which cost between $200 and $600, can help prevent costly coil replacements.
