"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

In most cases, repairing a radiator is more affordable than replacing it. A typical repair may cost between $100 and $200, while a replacement can average $1,500, with a range of $250 to $2,500 depending on the unit type. Radiator issues are often simple fixes for a professional, such as a blown fuse, malfunctioning thermostat, or a loose valve, and can take less than an hour. However, if the long-term costs of fixing the radiator are higher than replacement, it's better to get a new model. It is recommended to consult a heating expert to diagnose the problem and determine the best solution for your situation.

The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.

Most HVAC service calls include diagnostic fees, which could include checking on a specific issue you’re experiencing or running through a routine inspection checklist. If you called for a particular problem, the service call will also include an estimate to fix the issue, including materials and labor. Depending on your HVAC technician and the service you requested, you might also get a general inspection of your system components to ensure everything is working as intended.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.
