In light of the upcoming snowy weather take some time to keep venting clear from snow. Also if you have an oil tank that is outside it’s best to cover the filter and lines and protect them from the direct cold. Oil starts to gel around 20 degrees and any water in the tank will freeze.

I called my local oil company after waking up to find my furnace was not running, and I had already tried most of the resets and basic homeowner stuff with no success. They could not help me, and the service people they suggested wanted almost a mortgage payment to stop by my house just to see what the issue was. After a quick search, I located 603, and they were close by. I called them and got a real person who said he would be happy to help. He came right over and arrived when he said he would. Super personable and beyond qualified. In no time, he had figured out the issue, cleaned and repaired my entire system, and fixed a long-running hot water issue. And in the end, he charged me a fair price and offered follow up service if needed. I can’t say enough about this company. If you are in the Hillsboro area and are looking for a quality HVAC service company, I can highly recommend 603! They have truly earned my business, and I already have them on my calendar for next years’ ser...

Spoke with owner about propane conversion for our dryer. He was super responsive. Sent technician to do the conversion. Kyle was very respectful, knowledgeable and friendly. I’ll definitely be using 603 OBS again!

We just bought a mobile home with a furnace that hadn't been serviced in 3 years. We called a large local company who played around with it for a bit, got it to run and then left. It never ran after that. They never mentioned it was running at 60% efficiency or how bad the electrical was. We called these guys since they had good reviews. Kyle found out we had an air leak somewhere in the system and Peter showed us where the burner was completely broken apart and shorting it out. We decided to do a new furnace from them. They gave us a reasonable but worst case estimate, showed up on time, hauled the old furnace away and got it installed in just a few hours. They even swept up when they were done. They came in way under estimate and did an amazing job. I would recommend them to anyone I know, the price was very reasonable and they did an excellent job. I definitely would have thought we were going to pay a premium for the care they took and how good it looks now
