These folks are great for a/c and furnace maintenance and they do sell new systems. I had my system installed by Conway Services but there were issues. Mike, the service manager has been servicing my system for 6 years — before the new one and after. He has the best advice ready and knows his stuff. Really cool guy. The maintenance service runs $ 120 a year currently and they come out before winter to service the furnace and before summer to service the a/c. If you do that maintenance service, you get a discount on parts and a new system. I didn’t know that part til after my new system was installed. I have had them out before to service my system. A part was replaced and I had problems again the next day which happened to be a Sunday. A different guy showed up, the same part was bad again and he replaced it — no charge for the part or for coming out on Sunday. One would expect that kind of service but rarely do you get that in the HVAC industry. It was then that I replaced my whole system and Cordova keeps it running like new. I really appreciate these folks and the way they work with my schedule and how committed they are to their work. I highly recommend them if you are having trouble with your system or if you’re looking to replace it. Mike is professional as can be but will take the time to educate you and offer advice. It’s. Impairs like Cordova that take the hassle out of being a home owner.
