"Vinny came over to my home the same day to give an estimate as I needed to replace my exisiting humidifier. I already knew it wasn’t working and super old so best to replace it. He explained everything to me when looking at my furnace room. Explained the different size and efficiency of the various models I could use with the size of my home. Quick to schedule installation as well :) I will definitely use this company for future HVAC needs!"

Heating and Air Conditioning questions, answered by experts

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.

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.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

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.
