  • A-1 Heating and Cooling
    Went very well. The appointment was made for the day after I called. The technician Danny arrived on the front end of the appt window and did a professional and efficient job of confirming a failed capacitor and replacing it. The air conditioner is fully functional again. Responsiveness, as well as time and cost to repair, are worthy of a big recommendation

  • Castle Heating and Air
    We had Castle Heating & Air add an HVAC system to our home and they did a fantastic job. Richard was very thorough and communicated really well about the whole process. We all know that owning a home is not cheap with all the upgrades and maintenances you have to make which is why it's especially important that we do our due diligence to ensure that the company we go with will meet our expectations. Castle Heating & Air exceeded that. Their work was exceptional and professional. I highly recommend them

  • Castle Heating and Air
    Robert and Roberto did everything you could ask for during the removal of the old furnace and installation of the heat pump. They were professional and personable. They communicated their daily objective, updated us each day on how it went, and left the work area cleaner each night than when they arrived. We got multiple quotes and theirs was very competitive

  • Castle Heating and Air
    Exactly as planned. Richard and his helper arrived on time, removed our 60 yr old furnace and installed a brand new 96% efficient American Standard Furnace. There price was very competitive and the brand that they recommended was highly rated as well. I had some reservations with dealing with a company which had not been established for very long but after talking with Richard I knew that he would do the job the right way and I was right. I highly recommend this company

  • Magic Plumbing Heating and Cooling
    The whole service process was very smooth and efficient. The office person, Jessicka sent me the a clear and friendly message one day before the service to confirm the time and service. The technician, Jay G. communicated with me before arrive and was excellent on both people's skill and technical skill. He explain the situation well and finished the checks equipment, gas line and turn on the heatings in 20 min. At the same time he trained his younger associate, David, to share his experience with him as well. Jessicka followed the service immediately... A very good team work together! I will definitely recommend to my friends and will use their service again
