Doug is the ONLY person I will ever call for our HVAC needs! Just last week I texted him at 7 am that our unit was blowing but no cold air was coming out. By 10 he was here, fixed a condenser, and we were back in business. Honest, trustworthy, reliable, you can not ask for more! I pray he doesn't retire while I own a home in Arlington! read more

Doug is a fave in Arlington for his quality service, prompt attention, and reasonable prices.

Doug Marshall is amazing! Reliable and goes the extra mile every time. He comes through for my family every time.

We've used Doug Marshall with Seasons HVAC for the last two years, based on many MONA and Nextdoor recommendations, and we've been very happy. Doug explains everything well, doesn't oversell products or services, is prompt in responding and following through on service delivery, and is reasonably priced. He installed a new AC unit for us last year (for a good price), and the whole process from estimate to installation was great. We've had only one minor issue with it since then, and his response was amazingly fast and effective on that occasion. He literally had a technician at our house within 20 minutes of my call, and had it running perfectly again within an hour (at no charge). Awesome overall and SO much better than our preceding experience with others in the past. read more

Doug is the simply the best. He's incredibly smart and spots things before they become issues. He's also got great judgment and knows when something is worth fixing right away or can wait for a bit. We've had Doug work on our HVAC for about the last five years and had him install our new HVAC system (furnace and AC) when they got to the end of their (very long, thanks to Doug) life. Doug will also take extra time to think through solutions that end up saving money -- he saved me from having to rewire a big part of my house by doing some sleuthing and being willing to spend some time finding the best and most cost-effective solution. He's honest and trustworthy and doesn't mince words. Doug also just knows a LOT about everything, and always gives helpful tips about other items he might spot! read more

I was recommended to Doug by a neighbor when my AC died. He was able to fit me to his schedule for same day service and fixed the issue quickly and for a fair price. Wouldn't hesitate to call him again for HVAC needs. read more

Our AC wasn't cooling yesterday so I called Doug around 3pm today (a Friday) to request an appointment next week. He came within the hour!! He quickly figured out what the problem was, helped me to understand some maintenance we could do ourselves and got the AC back up and running. I appreciate his honesty and genuine care to educate and restore comfort to our home. Thank you so much Doug! read more

So it was a week of 95 degree days and our 22 year old HVAC unit was simply not cooling the house. We called another company first and they came out and basically charged us a lot and did little. If fact they made things worse. We then decided to call Doug at Seasons and he was over within two hours -- diagnosed the problem (faulty compressor), cleaned out the coils (which the other company failed to do),checked our Freon and cooled the machine (which was overheating) with our hose for about an hour. All the time he was with us, he explained everything he was doing in a way which was easily understandable. He also shared stories about the neighborhood, as he's a local Arlingtonian resident and made the entire process pretty painless. Moving forward he explained our options, and suggested we consider a newer unit in a few months, being that ours outlived its life expectancy. He was not pushy at all and explained the various levels and said, when you are really...."call me." Guess what, we will certainly call Doug, as he's our new "go to guy." And another thing...his pricing was extremely fair given the circumstances. Can't recommend Seasons Heating & Air Conditioning enough! read more

In a world where trust is so valuable and scarce, Doug M. excels. He cares for his clients, always picking up the phone even late on a weekend. He problem solves, and thinks creatively. If there is someone you need for any HVAC related work, use Doug. read more

I got home at 3:30pm on a Friday and discovered that our A/C was out. I called the company that installed it and they said they couldn't come until Monday. Based on recommendations that I'd seen on our neighborhood listserve for Doug Marshall, I called Doug. Doug said he was in the middle of a service call but would do his best to help us. Sure enough, Doug arrived at our house within 30 minutes. He diagnosed the problem, replaced the part that had died (he had the replacement in his van), and had our A/C unit back up and running within an hour. Doug also spotted a second issue and predicted it was going to become a problem pretty soon. Sure enough, it became a problem the next day -- I called Doug again at 7am that Saturday morning, he was at our house by 10am, and fixed the second problem immediately. I obviously didn't have time to shop around so I can't compare his rates to others, but my husband and I both thought his rate seemed very reasonable, especially for 2 calls on such short notice with such efficiency. Hoping we don't have a string of A/C issues but if we do, we'll be calling Doug first, no question. read more

Seasons Heating & Air Conditioning is an extremely competent and professional company. Doug Marshall,owner, responded quickly to our call for help with our boiler. Within hours the heat was restored to our home. read more

This winter, our boiler that that was installed in January 2015 stopped working due to a faulty low water safety sensor. The company who installed it sent a tech out who spent 3 hours on the wrong problem, charged us, and left. Doug with Seasons was referred to us from a local distributor and he came out quickly, diagnosed the issue, found a short term fix so we could have heat, and ordered a part for the long term fix. When the part came in he came right out and installed it, we couldn't ask for more. If you are looking for a straight shooter who actually has integrity and gets your job done right for a reasonable price then you should go with Doug at Seasons. read more

I cannot speak highly enough about Doug Marshall with Seasons Heating & Air Conditioning. After a few years of being jerked around and upsold by two of the big name HVAC companies, Doug has been a refreshing change for us. What has struck me the most about Doug is not only does he not try to upsell his clients, but he honestly tries to save them money by making suggestions about ways to buy time before making a repair, the cost saving benefit of insulating your home, etc. When he finally tells me I need to spend money to replace/repair something, I never have any doubts because I know he wouldn't be making that suggestion unless it was completely necessary. He also works hard to be available for emergency situations - he has arrived as soon as an hour after receiving my call. read more

I'll go with 5 stars. Came within 90 mins of a call when we were getting ready to leave on a trip and needed the leak fixed asap. Pleasant to deal with, knew what to do and did it, right. True expert. Happy to have him back anytime. Arlington customer. read more

Heat pump quit working. Called Seasons and Doug Marshall arrived within the hour. He quickly diagnosed the problem (bad capacitor), had a replacement part on hand, installed within a few minutes, and everything was good to go again. That's 5 star service. read more

There is a reason Doug at Seasons Heating and A/C has a 5 star rating and I would give him 10 stars if I could! Whenever the heat got above 90 degrees outside, the upstairs of our house would get unbearably hot. No one could figure out the problem - not even the builder. We were repeatedly told to just crank up the a/c on the lower level so that it would help cool the upper level. That was before Doug came to look at the problem. He not only pulled the prints for our house from the county, but tracked down all of the paperwork given to the original AC company. He discovered that when the house had been built, a smaller unit than what had been ordered had arrived, but had been installed anyway. Doug contacted the original AC company and got them to install the correct size unit solely for the cost of labor. Upon his most recent visit he also brought us enough filters to last the next 5 years as well as a new canister for our humidifier which had been ruined because none of our prior AC companies had changed it. There is no one else I would trust with our a/c & heating. Thank you Doug!! read more

I called after one of our AC units gave up, and in 85+degree heat! Spoke to Doug, who told me he had a number of other customers but would do his best to be here in 1 hr. Sure enough, he came after an hour, and went to check things out. Within 30-45 mins, he diagnosed and fixed the problem (a blown capacitor), suggested ways to prevent the issue going forward, and presented me with a very reasonable bill. AC back on and working, and we're no longer sweltering. Thanks Seasons! read more

Doug came out to our house within hours of us calling him. He fixed our aging AC unit within half an hour, all the while explaining everything he was doing. The price was very reasonable. He also gave us a quote for replacing our furnace and AC which we'll probably go with. Very friendly guy. Wish we had heard of him years earlier. read more

I called Seasons because my furnace fan was not cycling on with the furnace. Doug came out in less than two hours and diagnosed the problem. Initially over the phone he suspected that the circuit board may have had a bad relay so he brought one with him in case. He quickly saw that it was a bad motor so he removed the fan assembly and brought it back to his shop. He swapped out the motor, reinstalled it and we are good to go. This is the type of honest and prompt service you can expect from Doug and Seasons. read more

Seasons came highly recommended from a friend but I was still surprised when I called and Doug said even though he had almost a dozen other calls that day that he would fit us in to his schedule. Can he really be that good? Yes. I haven't been this impressed by any service provider in a long time. He came exactly when he said he would and efficiently assessed and fixed the problem. He was professional and knowledgable. I will recommend him to everyone. read more

Although our HVAC was 26 years old and ready to be replaced, Doug spent hours cleaning and fixing our system because I was 8.5 months pregnant in the dead of summer. He was attempting to give us some relief in the day or so it would take for the new system to come in. He took his time explaining the problem to me and the various replacement options available. My husband and I were both impressed with the fairly priced (and well-explained) suggestions he made for a new system, as well as with the quick turnaround from when we placed our order to when he was able to obtain and install the new system. He and his team were friendly, efficient, professional, and TIDY! We will absolutely call Doug for any issues that arise in the future. He is very honest and even gave us some suggestions for how to care for our system after the completion of our remodel (which would result in a lot of dust in the system. Note that this suggestion would require us to work with a different company, so it didn't personally benefit him to suggest it, but he knew it was best for the system.) read more
