Heat when it's cold.
Coolwhen it's not.
The neighborhood heating and air conditioning shop on SE Hawthorne. Furnace and A/C repair, new system installs and heat pumps, done by people your neighbors already trust. A lot of Portland still just calls us Baumer.
What we do
One shop for heating and cooling
Repair, service or a whole new system, both sides of the season. Here is the work Portland homeowners call us for most.
Furnace & Heating Repair
When the heat quits on the coldest night of the year, that's exactly when you want someone who picks up. We track down and fix gas furnaces, electric heat and older systems, then make sure the rest of it is running right before we leave.
Air Conditioning Service
A/C that can't keep up when Portland finally gets hot is miserable. We service and repair air conditioning so your home actually cools down, and we'll tell you straight whether it's a quick fix or something bigger.
System Install & Replacement
Ready for a new system? We install and replace complete heating and A/C setups, sized properly for your home. Customers keep coming back to us for their installs because we do it once and do it right.
Heat Pump Specialists
Heat pumps do the heating and the cooling, and they need someone who knows them. We diagnose and repair older units fast, usually sorting the problem and double-checking everything else inside 24 hours.
Home-Warranty Work
A lot of our customers are sent to us through their home warranty, and we work smoothly with those programs, including Fidelity. We handle the back-and-forth so you can just get your heat or A/C fixed.
Straight-Talking Diagnostics
Our techs explain what they're doing and why, walk you through your options, and give you a clear picture of what's likely coming next. No jargon, no pressure, just an honest read on your system.
The shop on Hawthorne
A local name people still trust
Walk into the shop at 3708 SE Hawthorne and you get the thing that's gone missing from a lot of home services: someone who knows heating and cooling, right there at the counter, ready to help. Plenty of longtime customers still call us Baumer, and that name carries the same promise it always did.
Our technicians explain what they're doing and why, lay out your options, and give you a clear picture of what's likely coming next. No jargon, no pressure. That's the reason people who found us through a home warranty end up recommending us to their neighbors.
We're open seven days a week because furnaces and air conditioners don't wait for business hours. Whether it's a repair, a tune-up or a full new system, we do the job right and make sure everything else is in good order before we leave.

The counter on SE Hawthorne. Real parts, real people, and a straight answer about your system.
Why Portland keeps calling
A perfect 5.0, 170 times over
Not a handful of reviews. A hundred and seventy homeowners, every one of them a five-star. That kind of record only comes from doing right by people, one call at a time.
Open every day of the week
Heat that quits and A/C that dies rarely pick a weekday. We answer seven days a week, from 7am, so you're not stuck waiting until Monday to be comfortable again.
Techs who explain, not upsell
Our people tell you what they see, what your options are, and what's probably next, so you can make the call with a clear head. Customers mention it by name in their reviews.
In their words
170 reviews. Every one, five stars.
“Very satisfied with Heating & Air Conditioning of Portland. The technician was courteous, skilled, and completed the work efficiently.”
“These guys are the absolute BEST! Great customer service and excellent work! They installed/replaced our heating and AC system for us. I would highly recommend Baumer Heating and AC for any of your heating and AC repairs or installs! They are quick, professional and reasonable! Thanks for doing such a great job!”
“Baumer heating was chosen for me by my home warranty but I've been very happy with them. They have been very responsive, knowledgeable, and quick with fitting me in (which is especially nice when you're having heating problems). I've had a great experience with them from start to finish and absolutely recommend them.”
“Baumer's is a great Heating & A/C company. The tech is knowledgeable, efficient and speedy with repairs. We have an older heat pump that has had 4 separate issues at different times, and they have always fixed it and made sure everything else was in good order in less than 24 hours. Would highly recommend this company. They work very well with our Home Warranty program through Fidelity.”
“I have had them out two times in less than a month (because of my A/C equipment issues not their work) and they are great! Chris is very willing to explain what he is doing and why. He explained all my options and gave me a clear understanding of what will probably be next. He was quick to come out for each service call, and he works efficiently. I definitely would recommend these guys for any heating and A/C work you need done!!”
