New HVAC filter, reset breaker. Thermostat batteries are fine. Still not kicking on. Sent Yelp message to RES because they have always been quick to respond. And they did this time as well and the woman who gave me a call was nice and tried to help. Pretty disappointed that they can't quickly swing by today. From what I've read, it's likely a dirty flame sensor or the ignitor switch (neither of which is a long job - I just don't have the tools). HVAC less than 5 years old, so parts are under warranty with RES; however, I had to call someone else. Bottom line: Someone else is coming today, but I could end up paying for parts. Kind of feels like my current needs weren't lucrative enough for RES to make a concerted effort to swing by.

Before he left asked if I need to pay next time while replacing part. He very clearly said there would be another labor $100 cost for me. Then he contacted me for replacement part within day, and he offered $400 for the item. I checked the replacement part price from online stores, it was never $400 at any store, and I found the same part with $150 price. Then I let him know not to order for the part, instead, I would order it. Now, the replacement part is ready and this company is requesting $250 for labor fee which we already discussed. Moreover, they are changing their speaking as if it was about distance of location. What is funny my home is pretty close to their location around 15 min most. Their behavior is not ethical, and I am not stupid. Briefly, if you want to spend more money in than regular cost , you can go with them.

Called Friday morning and the receptionist was amazing and got someone to our house that morning. Full diagnostic told us the compressor went bad. Our unit was 13 years old, so it was about time for a new system. We decided to replace whole system as replacing a compressor is quite expensive basically half the cost of a new one. Mike came that night to price out a new system. I got two quotes from other companies. But decided on Shanahan because of their reputation, service as well as pricing. Talked with Mike and Conner (the owner) about our options and they came on a Saturday to install even though they didn't have an opening until Thursday. The owner himself came with a couple guys and replaced our system. They were very polite, did excellent work and we were back up and running. Plus they had very affordable pricing. These guys care!
