"Our heat pump failed. The company that I have been using for AC servicing was not able to repair my heat pump in a timely manor, claiming they were waiting for a part. After enduring several weeks of hot weather in desperation I called Oregon Heating and Air Conditioning. Their bid was much lower and the repair was completed just in time before several !00 degree days were approaching. I wish to thank Clint for doing an excellent job of answering my questions and Sergio most of all for braving the heat of the day and working very hard to get the heat pump going. My wife and I are 75 and enduring heat is not as easy as when we were younger. Both Clint and Sergio are heroes for bringing much needed comfort to me and my wire. Thank you so much."

"ACS installed a new Bryant heat pump + furnace. The equipment is high quality and the team was knowledgeable, flexible, and willing to answer all my questions. They accommodated a change in scope on the day of install from just installing a heat pump to installing a furnace + heat pump combo. This set the team back a few hours for the last minute parts request, but they powered through a very long day and stayed until the job was finished. All customer service goes directly through the owner operator. Originally this seemed like a plus, but I think they would benefit from support staff. I needed to edit and downgrade this review after a few negative experiences. Some changes are related to issues noticed after the install. The unit was not secured to the pad outdoors and also was not attached to the house. Holes cut into the corner of the garage slab in order to pass through the lines were not patched, leaving a break in the envelope. Mark promised to follow up on both of these, but he did not send anyone out to take care of this. Mark also directly promised that our install would qualify for Energy Trust of Oregon incentives for $3000, when in fact it is clear after speaking directly with Energy Trust representatives that our install did not qualify for any amount of rebate. This promise was echoed throughout the quote and the install process. I believe that the lack of a support staff is causing some shortcutting or disorganization when it comes to managing some of these details - I would prefer to assume that ACS did not know the details of the incentive rather than that they purposefully deceived me, but I dont feel comfortable recommending them given these circumstances."

Heating and Air Conditioning questions, answered by experts

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.

You should have your AC coils cleaned once per year. To keep your AC unit in tip-top shape, consider cleaning your coils twice yearly—before and after air conditioning season. That way, the pro will remove any dust, dirt, and debris that has built up over the winter and catch new grime that accumulated during the summer. Additionally, if you’re handy, you can tackle any in-between cleanings yourself with a special fin comb.

You can protect your air conditioner in the winter by turning off the power at the thermostat and performing routine HVAC maintenance in the spring. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home.

AC drip pans last five to 20 years, depending on the material. Plastic AC drip pans last five to 10 years, while metal pans can last over 10 years. Plastic AC drip pans are vulnerable to cracking in response to temperature changes. Metal drip pans are prone to rusting over time, which can also lead to leaks.

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.
