"Royal Comfort installed our central AC system. It was completed on time and they were very clean, professional, and very fairly priced. They answered all of our questions and concerns and we continue to use them for our seasonal heat/ac service."

"communication I found was poor. I felt I needed to reach out to them instead of them reaching out to me when I was the customer. at one point, figured I had not heard from them and was ready to just find someone else. I had to call them and when I did reach them wasn't even sure they knew who I was. they gave me a quote on 2 unit choices with nothing more than the price and the manufacturer, I had to call them to get more info on the units and do my own research. other than communication, things went well, clean, on time, polite, fair price,"

"John is extremely knowledgeable and passionate about his craft. We first started working with him when we were first time home owners in White Plains. Now that we've moved, we continue to call on him for his expertise and professionalism. He has recently done a replacement job for us and we couldn't be happier with the timeliness, cost, and overall quality of service. He is very accommodating and answers any questions without making you feel like you "should know" things. We look forward to continuing our business with him for other HVAC projects down the line."

"Andre and his team did an AWESOME job removing my decades-old HVAC system, including the air handlers, and replaced all with new, energy-efficient equipment in a matter of days. The only hiccup was waiting on the town permit, but once it was issued, the Supreme team was onsite and had everything working perfectly. A job well done at a more than reasonable price - HIGHLY, HIGHLY recommend!!!"

"We are extremely satisfied with the experience we had with Dario. Tony gave us a great estimate for a complicated job. He also gave us his honest advice about what to do and not to do. Glad we listened to him. He spent the time to figure out how to make something work even though it didn't look likely. The team was professional and friendly. We will definitely call them back for our future HVAC projects."

Heating and Air Conditioning FAQs, answered by experts

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. 

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.
