"As before with previous work done by Absolute Temp Control, I wish there was a higher rating than 5. 2 days ago the air conditioning in the house stopped working. The Portland area has been enduring a series of 90-100 degree F days. John came out within ~1 hour of when I called. Turns out the HVAC unit is ~20 years old and on its last legs. John replaced the thermostat and fixed the wheezing HVAC’s other maladies. There are three of us formerly sweating humans and 2 no longer panting dogs here and we are all grateful to Absolute Temp Control for their speedy repair."

"Max & Joe came out to our house and were not only professional but also very pleasant to host in our home. They made the entire experience prompt and pain free. While bringing a good amount of great advice for our air quality it was evident they knew exactly what they were doing and delivered on their promise of great quality service. Will definitely be calling Better Air for our next service."

"Six years ago, a few days before Thanksgiving, my furnace died. Oregon Heating juggled existing appointments in order to find time to install a new one so I wouldn't have to be without heat during the cold winter days. They cleaned the house air ducts at the same time. All was done quickly, courteously, and professionally. I've continued to Oregon Heating for yearly furnace checkups, and their technician, Dave, is a delight: polite, personable, and patiently thorough in answering all my questions. I'm completely satisfied with this furnace. Thank you for your terrific product and staff!"

"I am so pleased from start to finish with Integrity Air. I called in Jan for a quote and Ben was very professional and gave a great and reasonable quote for a new AC. The installation crew guys (Kyle?) just left after installation the AC (on a 28 degree day might i add). I highly recommend Integrity Air."

"After looking at reviews on Angie's List and then getting quotes from 3 different companies, I decided to go with Service Now, Inc. From the very first contact, they were impressive. Jason Johnston, the owner, came to our house on the initial visit. He asked many questions about our heating and cooling habits. More importantly, he listened to my answers and suggested options to suit our criteria. Throughout the entire decision making process, I had numerous questions about the various choices available in the Carrier product line. Jason was extremely patient and addressed each and every concern, both by phone and email. The end result is a heating and cooling system that meets our needs, not one that we felt pressured into buying. Because we were buying between the heating and cooling seasons, they were able to install almost immediately. The installation went smoothly. Kelly, the installer, has years of experience. He was able to custom make a section of ductwork with dampers to allow for better airflow to the second story of our home. He, too, was able to address any questions I had during the installation process. He left both the furnace and air conditioner installation sites clean. All debris and packing material were removed. Kelly also programmed our new thermostat and gave me an easily understood lesson as well. When presented with the final bill, the amount matched the initial bid. There were no hidden costs or extra expenses."

"I was referred to Columbia Heating and Cooling through NW Natural. My furnace randomly stopped working (later found out it was because of a squirrel...) during some of the coldest nights we've had so far this winter. The tech showed up ahead of the scheduled time and was able to fix my furnace within 30 minutes. No complaints, and glad to have heat again."

"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."

"It went extremely well. Punctuality was perfect. Paying attention to details was perfect. Knowledge and professionalism were perfect. The price was competitive. We interviewed 5 different providers. Ultimately, Columbia seemed to stand out best. We tried it, and we were quite happy with the choice. The service cost was for two independent air conditioner systems ( we have a large, long house), and one new furnace."

"Had a 40 year old Lennox furnace that gave up the ghost. HomePro Heating + Air responded to a request immediately and within a amazingly fast removal in installation of my new furnace. The team was extremely polite and professional and respectful of my home. Price quoted was way better that I was expecting. If you are looking for a great team of professionals. Look no further. Thank you so much and Happy New Year! - Jan L."

Air Conditioning questions, answered by experts

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.

The cost of annual maintenance depends on the type of HVAC system you have. AC service typically costs an average of $200 but ranges from $100 to $550. If your system needs repairs, the price will vary significantly depending on what needs fixing. However, addressing the issues as they arise can prevent further damage to your unit and keep it operating efficiently for much longer.

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.
