"The team of four was very professional and performed an excellent job in a record period of time. Just one day to take the old furnace away, replace all the old boots and duct work and install the new furnace. They paid a lot of attention not to damage or dirty the floor/carpet. I am very happy with their performance. They may not be the cheapest on the block but it was all worthed and you only have to do that once in your lifetime."

"My family and I just moved to a new home here in west Portland, One day I decided to open up one vent to see what was inside. I was in shock of how filthy my air ducts were! So I called Green Apple duct cleaning, And let me tell you, they new exactly what to do! By far the most professional and hard working group I've ever had clean my air duct system, if their is any problem at all, they will fix it! I have a relatively large house, and only paid 250! It was way cheaper then prices from other companies! I would highly recommend Green Apple to everyone!"

"MGM Construction provided excellent work. Adolfo and Gerardo were responsive and dependable. They completed the work in the time allotted and were willing to complete other house repairs such as floor sanding, window and ceiling repairs, etc. The brothers are so easy to talk with and provided valuable professional advice. Their pricing is reasonable and fair. We will hire them again and highly recommend them to others."

Boiler Repair FAQs, answered by experts

Although boilers can last 15 to 20 years when maintained properly, you may run into some common problems like oil burners and transformers malfunctioning; cracks in the heat exchanger; clogs in the heating oil pump, burner nozzles, or fuel pipes; loose wiring connections; and damaged valves. Many of these problems can be caught early on during annual maintenance services. You might also have an issue with your fuel source if you have a gas or oil boiler. Make sure your other gas appliances are working or that you have oil in your tank.

Properly maintained stucco can enhance insulation, reducing energy loss.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

Yes, many HVAC professionals offer emergency repair services for furnaces and other heating systems. These services are especially common during the winter and colder seasons when functional heating is crucial.

If you hire a professional to replace your gas furnace’s thermocouple, you’ll usually pay between $150 and $250. Since thermocouples often fail due to a lack of maintenance, you may be able to avoid—or at least delay—a thermocouple replacement by taking good care of your furnace. This means scheduling annual furnace inspections, changing the filters at least once per season, and cleaning the burners occasionally.
