"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."

Heating and Air Conditioning questions, answered by experts

Yes, scorpions can enter a home through AC vents, especially if the system is not well-sealed. As excellent climbers, they can scale a home's exterior and squeeze through gaps as small as 1/16 of an inch. Scorpions are often attracted to the moisture around air conditioning ducts or seek cooler areas during hot weather, using vents as a pathway inside. They may slip through small openings where the duct meets the vent cover and travel within walls before emerging. To prevent this, inspect your vents, seal any gaps, and consider installing fine mesh screens.

Yes, you can clean your air conditioner filter as a temporary fix for cleaning up dirt, but you’ll eventually need to replace it once the dust starts to accumulate. Use a vacuum with a hose attachment to clean your air filter at least once per year or more often if you have pets.

You may never need an AC recharge if there are no leaks. However, if your AC unit has a leak that cannot be patched appropriately, you’ll need an AC recharge every time the freon level drops low enough that it disrupts your system—this could be once every two to three years. It all depends on the size and frequency of the leak.

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.
