I called them monday morning and they said they can come and check my heating unit as soon as possible. I thought it’ll be next the next day. But they called around 3 in the afternoon and asked if I was home. They came to check my furnace the same day. Didn’t charge me anything for the check up since it was a minor problem with the ignitor. However, they looked at my air ducts after I told them about the smell. Turns out my air ducts needed cleaning ASAP. I asked for them a night to think over and to get a second opinion. After i made some quick calls, I realized their estimate was fair and besides, they were closer to my home. So I asked them to send guys the next day to clean up my ducts. They took thier time cleaning it and they did a good job. Happy with thier response time and thier services...
