"FIVE STAR BUSINESS!!!!! This business was recommended to us by Roth HVAC in Canby. The initial phone call was answered in the most professional and polite way. Was able to get an appointment within a few days. We had soot and smoke damage to our home from the Mollala fires.We had a restoration service that worked on removing the soot. But we also wanted our ducts cleaned. I ordered the duct cleaning, plus the dryer vent cleaning and the Antimicrobial Treatment (highly recommend). Our visit was scheduled for 8AM. Twenty minutes before arrival, we received a call with the ETA. Well, Neal and Jesse................competent, thorough, professional, incredible people. And a great sense of humor. Answered all of our questions, very knowledgeable. Followed all Covid-19 guidelines from masks to distancing. Very respectful. If you need quality duct cleaning done right, call them now!! Seize this opportunity to have the work done professionally."

"Excellent service. Jace not only helped me with this but also with other options to consider in the future one it is time to replace our existing forced air furnace. He was very knowledgeable and took the time to answer all my questions. And the cost was lower than other HVAC companies quoted us for the same equipment. Will definitely use them again for any future HVAC needs."

"Beyond excellent. Found out our shops HVAC was out, mind you it’s already 2 pm and pushing 90 degrees outside. Contacted Revival Energy and within an hour, a repair man was addressing the issue. He was able to fix the problem with the upmost kindness and professionalism, all while maintaining social distancing. Definitely saved the day for the shop. 11/10 would recommend."

"Columbia Heating and Cooling were by far the most knowledgeable and professional company I had an estimate from. The owner, the service techs, and the guys who do the installation were all nice people and easy to work with -- they were careful and thorough, and happy to answer all my questions and problem-solve with me about optimizing our HVAC system. We live in an older house, and they improved airflow to the upper level, added return vents, and advised me on realistic energy saving. They also ran a blower door test. They were so good that when our water heater started to fail, I had them do the replacement. They offer competitive prices and in my experience they spend the extra time with the customer that makes all the difference. I didn't see them as just doing their job -- I saw them as helping me."

"It was really a great experience from the very beginning. I found them online, on an advertisement on my phone. I clicked on the ad, which led me to their website. I filled out the contact form and within 2 hours someone called me to make an appt. They explained over the phone that it would be an "arrival window" of 3 hours, and I was expecting something like that. They called this morning to let me know they were on their way, which I thought was very nice. The technician, Dave, arrived at the very beginning of their "arrival window", which was also nice. The technician arrived in a nice, professionally lettered company van, which I appreciate. You'd be surprised how many companies DON'T do that. Dave was in a nice uniform, seemed clean-cut and pleasant. I showed the him around to where my furnace, thermostat and A/C unit were and left him to do his thing. All I had requested of them was a tune-up and just a once-over on both the furnace and the A/C unit. Just some preventative maintenance, so that we wouldn't have any problems [that could have been prevented] this winter with the furnace or next spring when we went to turn on the A/C unit. He did find some things that needed replaced and cleaned out with our A/C unit and said he was surprised to hear it was still working well. It would have probably failed next season if we hadn't have had him out to fix these problems. There wasn't much wrong with our furnace, but I was glad he checked it out. He replaced our screens in our furnace. That was cool that this was included as part of the service call. He also stayed and talked with me for 5-10 minutes about the age of my furnace, what to keep an eye out for, and how much longer I should expect it to last. That was very nice and I could tell he really knew his business well, which added to my confidence in this company. The service took about 90 minutes and I felt the price they charged was very fair. It was probably more than some companies charge, but I would rather have a really professional outfit for a little more money than save money and have a less professional company. So to me, the rate I paid was a good value. I was just impressed all the way around with this company and with Dave. I'd recommend this company to anyone looking for HVAC work. They are a professional outfit, all the way down the line.

Heating and Air Conditioning questions, answered by experts

While both have advantages, a split system is generally cheaper than a ducted one. Because they are less invasive to install, the labor costs are lower, and they can be more energy efficient. But, a ducted system might be worth the investment if you run it more frequently. 

Air conditioners and dehumidifiers are actually quite similar, though they perform different jobs. Dehumidifiers reduce moisture in the air, while air conditioners work to cool the home. A good central AC unit will naturally perform a certain level of dehumidification due to its design, but it will not be able to handle excessive levels of moisture.

There are a few reasons your AC is running but not cooling your room. Thermostat issues and dust and debris, which can clog your system, are common problems. It could also be a broken component, such as a compressor, blower fan, or evaporator coils. You’ll need to call a pro to diagnose the issue.

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.

Yes, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.
