Canoga Park Heating & Air Conditioning are great. I've used them in the past and they have always been on time, efficient and friendly. They are also very clean and do not leave a mess. They are communicative and explain everything very well. Most recently I had an entire air conditioning unit replaced and a brand new one put in. It was a really big job but they were done in one day. When I had them do the estimate for the job, they were very responsive. They had just had a cancellation, so they were able to squeeze me in their schedule really fast and gave me a date just two days later. They did very good work and I'm very happy with them.
