Frequently Asked Questions

Have questions? We are here to help. Still have questions or can't find the answer you need? Give us a call at 508-623-6952 today!

  • When should I consider replacing my system?

    Replacement becomes necessary when the existing hardware is simply too old or damaged to be worth repairing. Owners may also opt to replace early for the sake of energy efficiency or greater comfort control.

  • Why is my AC not getting as cold as before?

    Low refrigerant levels are a common cause of poor AC performance. You may also notice a drop in output due to other problems, like insufficient insulation or poor air circulation.

  • What should I do if my unit stops working suddenly?

    Suddenly losing your AC in the height of summer is no laughing matter. Give us a call for emergency air conditioning repair and other urgent services.

  • What are some of the most common problems with air conditioners?

    Faults in the internal circuitry, component failure, refrigerant leaks, and insufficient BTU output for the target space are all common issues in New England.
