    Providing excellent customer service and willing to answers all my questions in regards to replacing the furnace and AC. Able to understand my needs and goes beyond my expectation. AC broke during this summer and we were feeling very hot and humid inside the house. Moreover, the furnace needed to be replace since it was undersized and not able cool and heat the entire house. Kal was able to accommodate and schedule to replace the AC and furnace as soon as possible. His installation staff were on time and very clean with replacing both units. They were able to provide a better understanding and showed what was the problem with the furnace and AC unit. Also, Kal was willing to meet you in person and confirm the installation afterwards which provided quality assurance that my needs where being taking care of. Kal and his staff are very professional and showed commitment that the installation will be completed on time and properly. Willing to do business again in the near future and highly recommended.

    Great service, the owner and staff showed up on time, diagnosed the problem and fixed it. They replaced my furnace coil and also installed the air conditioner. The price is very reasonable. I will use the service again and definitely recommend to my family and friends.

    I would highly recommend this company for all your air conditioning and heating needs. In February 2019 they located an issue with our heat pump and did the warranty work and got things working again in a very professional and responsive way. Today we had an issue with our air conditioning unit. Again they were able to quickly locate the issue and deal with it. Their pricing is very reasonable, their employee that attended was very friendly and very knowledgable with what he was doing. I would not hesitate to contact them again. I highly recommend these guys!!

    3How often should I replace my filter?
    The best time to change your air filter is right before the major heating and cooling seasons, in the spring and fall. It’s also a good idea to check your filter every other month to determine if it’s clean enough to filter the contaminants effectively.
    4How often should I service my HVAC system?
    It’s important to schedule a maintenance appointment for your HVAC system at least once a year. Spring to early summer is the best time to do this before the extreme temperatures have arrived.
