"I had a great experience from start to finish with this company. They were able to install my new AC unit quickly, which I was thankful for, considering how hot it has been. Throughout the entire process, they were transparent with their pricing, explained everything clearly, and never made me feel pressured. Dylan and Tristan were incredibly knowledgeable, professional, respectful, and kind. They took the time to answer all of my questions and made sure I understood what was being installed and why. I was honestly pretty stressed about having to replace my AC unit, but they made the entire experience easy and worry-free. I would absolutely recommend this company to anyone looking for honest, reliable HVAC service. Their customer service and quality of work exceeded my expectations, and I couldn't be happier with the experience."

"A-Moonlight provided timely and professional service. They were able to diagnose issues with my A/C and furnace quickly and explained the issue and their proposed solutions. Brent made me aware of my options for repair and what services were necessary and what was not. They were able to install the parts I purchased and service my furnace and A/C within a few hours. They got everything working in one trip and charged about 1/6th of what a competitor was asking. I would highly recommend A-Moonlight for any residential HVAC needs and I will be hiring them in the future should I need any other HVAC services."

Heating and Air Conditioning questions, answered by experts

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.

No, a furnace is not the same thing as an AC, or air conditioner, but these are both parts of an HVAC system. They both use air ducts to transport cool or hot air around your home to achieve a comfortable temperature set by your thermostat. An AC runs on electricity, while a furnace can use different fuel sources.

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

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.

Your AC might not cool after a power outage because of a tripped circuit breaker, blown fuse, or damage to the compressor or capacitor. If you notice your AC not working after a power outage, in most cases, the breaker has tripped or the system has built-in brownout and blackout protection. Reboot the AC by turning it off at the thermostat, resetting the circuit breaker, and waiting 30 minutes to turn the AC on again.
