"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."

"I first contacted Valley to get a quote on how much it would cost to get air conditioning installed. I live in an older town home that is approximately 1100 sq. ft. They sent someone out to take a look and see what was involved. He was very professional and explained what was involved including getting permits from the city. He quoted the amount and provided me with an invoice. I contacted them 3 months later to say I was ready for the install. The installation turned out to be quite challenging due to the way my home is constructed, but Valley made it work. The service person had to stay a few hours longer but I wasn't charged anything extra for it. They stuck with the amount of the estimate that was quoted. It's only been a couple of months since the install, but I have to say my only complaint at this point is how cold it gets when I turn on the air. But that's a nice problem to have. :)"

"A few days before contacting "Comfort Energy", my furnace started making a loud rattling noise whenever it was turning on. It sounded like a helicopter. This happened while my husband was traveling on business, who is an expert on taking care of things like this. While I was not sure what to do, I Googled and found out more about the problem. What made me quickly act and find "Comfort Energy" was reading about how seriously dangerous this problem might be. I read that it could be a cracked heat ex-changer which can cause fire. So right away, I turned off the furnace then next day called "Comfort Energy".  Having read the excellent reviews, I decided to give them a try. Excellent customer service. Olga and Frank both were very professional and helpful. Olga quickly scheduled the service. Frank was extremely knowledgeable and professional. Same day my husband was back from his trip and met with Frank. He was impressed and happy about how Frank handled the case. We will definitely call them again in case of any HVAC issue. We strongly recommend "Comfort Energy" for their expertise, professionalism, and excellent service,

"John did an amazing job with our HVAC system! From the moment he arrived, he was professional, knowledgeable, and took the time to explain everything clearly. His workmanship was top-notch, and he made sure everything was working perfectly before he left. It?s hard to find someone who genuinely cares about doing quality work, but John definitely does. If you?re looking for an honest, reliable HVAC contractor who takes pride in what he does, I highly recommend John. I couldn?t be happier with the service!"

"Great job estimating HVAC requirements, as well as a smooth and detailed job with actual installation. John would consistently set up expectations on installation details, noise-levels, arrival and exit times, etc. He is highly professional, very detail-oriented about time taken and strict with timelines. Both my heating and AC work perfectly!"

"Rittinger responded quickly. Alan, the tradesman they sent over was professional and quick. I hired them to install a clothes dryer vent and to open up a vent in my garage for the hot water heater. The work was high quality and installation was clean."

"Great team! Mark, Sergii and Pavel replaced my furnace and installed an AC. It was a real pleasure to work with them. Mark listened carefully and provided several options for me to choose from. He was also flexible on scheduling the work to match my family needs. Sergii and Pavel performed the installation exactly as planned, kept the house clean, and payed a lot of attention to the aesthetics of the visible parts of the system. They explained to me where they'd run the lines, what were the options and why they preferred one over the other. I'm very happy with the choice of brand and model and with the installation. The team really cares about their customers. Thank you!"

Heating and Air Conditioning questions, answered by experts

When your AC contactor goes bad, you might hear chattering or buzzing noises coming from your air conditioner. You may also notice that your AC is running but isn’t cooling your home. In some cases, your air conditioner might not even turn on at all. There could also be physical damage, discoloration, or corrosion around the contactor.

While many states do not have specific licensing requirements for HVAC companies, your local city or county might. It's always a good idea to check local requirements online and use a tool like Angi’s contractor license lookup to confirm that the company you’re considering is licensed. Regardless of licensing, you should always ensure the company you hire is fully insured to avoid potential lawsuits if a technician is injured on your property. Additionally, it is recommended to check if the company holds third-party certifications, such as North American Technician Excellence (NATE) certification or R-410A certification, which qualifies them to work with HVAC refrigerants.

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

When an evaporator coil becomes faulty, it can result in various problems within your HVAC system. These problems could include reduced cooling or heating capabilities due to ice formation and obstructed airflow, along with increased energy consumption and higher bills. Additionally, a damaged coil may lead to refrigerant leaks, which are environmentally harmful and decrease overall system efficiency.

Ultimately, if not addressed right away, a bad evaporator coil can even lead to a complete failure of your HVAC system. That’s why timely repair or replacement is crucial to maintaining your family’s comfort and your HVAC’s efficiency.
