Q: How much does it cost to fix a leak in an AC unit?

• <div><p>Fixing a leak in an AC unit costs $200 to $1,600, depending on the type of leak and any related damage. But depending on the age and condition of your AC, it might make more sense to <a href="https://www.angi.com/articles/it-time-repair-or-replace-my-air-conditioner.htm">replace the AC unit instead of repairing it</a>. If your AC is only a few years old and relatively problem-free, then repairing it is the right call. But if it&rsquo;s nearing a decade old and has other issues, consider replacing it. </p></div>

Q: Can I save on my air conditioner capacitor cost by installing the unit myself?

• <div><p>Yes, you can potentially save $60 to $200 by handling your own air conditioner capacitor installation. However, capacitor replacement comes with the risk of electric shock. Only attempt this if you have the knowledge and protective gear to carry it out safely. Otherwise, we recommend hiring an HVAC pro with the experience to properly diagnose the issue and avoid damaging other parts of your AC unit.</p></div>

Q: Do mini-splits use more electricity than window units?

• <div><p>Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month). </p></div>

Q: Is 78 degrees too hot to sleep?

• <div><p>While personal preferences widely vary, sleep experts say the best temperature for sleeping is between 60 and 67 degrees Fahrenheit rather than 78. If you do choose to sleep with your AC unit tuned to 78 degrees, you might want to use only a sheet or light blanket rather than a comforter. You might also consider installing a window unit in your bedroom so that you can be cooler in bed without wasting energy cooling the whole house.</p></div>

Q: Do HVAC zoning systems save energy?

• <div><p>Yes, HVAC zoning systems offer energy savings by allowing precise temperature control in different zones in your home. Rather than conditioning the whole house uniformly, these systems direct airflow where needed, preventing energy waste. Tailoring comfort to specific areas reduces energy consumption and lowers utility costs, making HVAC zoning an energy-efficient choice.</p></div>

The Maine Air Comfort team is exceptional. They were able to come out for a quote right away and in less than a week installed my new boiler. Rob took the lead on my project and was excellent with communication, competent, and thorough.

"Cam did a great job doing the installation and explanation of the heat pump. He also took care of registering the heat pump so everything was taken care of for us. The rebate from the state was also taken care of and deducted from our bill so we only paid the price of the heat pump with the rebate included. This is a big advantage because you are not paying the extra $2,000 for the bill and then waiting to get the $2,000 back from the state which could take weeks. They did a great job."

"Josh installed a new water heater, provided us with instructions on proper use and maintenance and has serviced it since. He is honest, thorough, and trustworthy. He also maintains my dad’s HVAC needs too. He has come out for emergency calls too. Suggest things to prevent future additional repair expenses. His prices are reasonable, especially for the personal, friendly customer service and service provided. I would highly recommend Northwoods HVAC."
