"This guy is a real pro! The original installer came out and gave up on the problem, and I never heard from them again. Duke came out, and diagnosed the issue in an hour. He even submitted the request for a part under warranty, received it, and came back to install it 2 days later. The cost was very reasonable. Thanks Duke!"

"The TASK service professional was prompt, friendly and explained very thoroughly what he was going to do. He was very thorough and kept me apprised of the vent and HVAC conditions he noted. After the vent system cleaning was done I noticed a big improvement in air quality > I could breath easier and deeper, the air in my home was fresh and I've also noticed that my home heats up faster and stays warmer at lower thermostat settings. I highly recommend TASK."

"My wife and I bought a house a couple years ago, and became owners of a radiant heating systems installed more than 20 years ago. Tony and Damian did a great job of understanding how my radiant heating system works, what repairs were needed/what was failing, and where upgrades were needed. They replaced the pump, both expansion tanks, and the neutralizer. Additionally, they noticed the hot water tank was installed incorrectly, and the hot and cold water connections were flipped. It's amazing the system worked, and it's nice to have a system that's correctly installed (even if it's 20 years later!). Additionally, they secured the expansion tanks to the wall (now required by code), replaced the deteriorating copper pipes connected to the neutralizer with plastic (I'm sure this is code now as well), and re-routed the overflow pipes to the outside (rather than the floor!). You can't go wrong with these guys, well done, they're true craftsmen to the trade."

"Absolutely the best HVAC company in the area. If you are looking for a company for your HVAC needs, look no further. It is superb in every aspect: customer service, onsite specialist who did the inspection and quoting, technicians who installed the system. Their price is extremely competitive, especially for the high end systems. I was shopping for a 80% 2-stage furnace but I ended up getting a Lennox 99% variable-speed furnace because the price was too good to pass. But it is money well spent. It is so quiet and powerful. I highly recommend Air Sharks. They actually put a smile on our faces."

"Smart Heating and Air Conditioning was the most professional, friendly, and knowledgeable company I’ve worked with. From our first contact, we felt like we were working with family. Our furnace went out and the techs and installers were all so amazing with keeping us all informed, especially Susie who works in the office. But what really showed me how great this company was, is that they saw our handle to our screen door wasn’t functioning and they were so kind to offer to fix the issue. They fixed it in 5 mins. You don’t see this type of generosity anymore, so we appreciate that! Our furnace and air were replaced for a great price and we couldn’t be happier. I would highly recommend this company for your heating and conditioning needs!"

"The team at Ramirez Duct cleaning was great to work with. My goal when having them come over was to have them clean my vents and inspect my heaters for any other issues. They showed me that my Furnace had never been cleaned, which would lead to more dust in the air. They also helped me fix and clean a wall heater and found an old rats nest on my roof that was a fire hazard. I recently had my ignition go out and called Ramirez duct cleaning to come back. They were able to find a replace part and get me up and running for a reasonable price. If you’re like me and know nothing about your heating system, you can trust these guys to give you a detailed over view of what you have and what needs to be cleaned. They also took strict covid precautions and showed me everyone’s temperature before entering the house."

"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."

"Nasir did a great job! The service was very easy and quick to schedule and they communicated with us throughout. The fireplace had never been cleaned before and is now spotless with no residual smokey smell. Nasir was very friendly and even fixed and issue with our flume that was causing it not to open all the way. We are very pleased with the service!"

"Very nice people. hey seemed unfamiliar with ceiling fan receivers (and **varistors** that come with them). They also left the fan a bit out of kilt, but they came back and fixed it."
