"My HVAC went out right before the cold snap and it was really cold in the house. I had called another company and they were thousands more so I took a chance and called Arnold’s and it’s the smartest thing I have ever done! The unit is excellent and will save me money on utility costs. He was there Monday morning and had me up and running in no time! He knows what he’s doing and didn’t tack on a service fee and other additional costs. I’m so glad that I found him and I highly recommend him for your HVAC needs. You won’t regret it! Thanks Arnold’s"

"This young man was very efficient and communicative. He was extremely conscientious and exact about his work. He was considerate about caring for our home by carefully closing the door and wearing foot covers on the carpet. He installed a window unit in an upstairs bathroom. Did an excellent job. Would hire him again if needed."

"Ms Molly and her team at Outshine Cleaning Services are amazing. My mom recently move into our mother-in-law suite, and we needed help. Outshine Cleaning came in and whipped this house back into shape. They are thorough and reliable. My mom brags on them all the time ( which speaks volumes.). The move things to dust, clean under tables, and everything sparkles when they leave. I am a real customer and I couldn’t recommend them highly enough. Thank you Ms. Molly for all you do. We appreciate you so much !"

Heating and Air Conditioning questions, answered by experts

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.

You should clean your air conditioner at least once per year, but you may need to clean your whole HVAC system (including the air ducts) more often. According to the National Air Duct Cleaners Association, you may need to clean them more frequently depending on factors like whether you smoke, have pets, or have allergies.

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.

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.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years
