What Our Customers Say About Our HVAC Service
They did some HVAC repairs for a property we had under contract. They were reliable, well-priced and communicated well even though we were not on-premises to chat about the repairs. Helped us get our house sold, so thank you!
Meg M.Meg M.Arlington HVAC Customer (Arilington - 10.2.22 - Yelp)
Working with CD Shanahan’s Heating & Cooling was a great experience. Technicians were able to fit me in next day for an AC and Heat install. They were on time and worked quickly to get our unit back up and running. They were also fair on pricing and were very honest with what I needed.

These guys are the best!!! Brandon did a great job. R&B Electric told me I needed a new system that would cost $12,000. I called Shanahan’s and Brandon cleaned the coil and replaced the motor and the system is working great. And a fraction of the price R&B quoted. I highly recommend Shanahan’s.
Carla G.Carla G.HVAC Customer (Alexandria - 7.12.22 - Yelp)
I was referred to this company & Mr. Connor Shanahan by a client of mine that I have known for years. I found the owner, Connor to be extremely responsive during an emergency situation where one of our rental townhomes had no A/C. He was able to do a high quality, professional job with a quick turnaround time so our tenants only had to spend one night in a hotel.

So we started using him for all of our rental homes & referring their company out to other associates. I couldn’t be happier with his company, professionalism & expertise even when dealing with a complex problem. I highly recommend them to anyone needed to repair or replace their HVAC system. Thank you so much Connor! You have no idea how much you helped us the past few years.

We had excellent service from CD Shanahan’s to replace our water heater. They were professional, knowledgable, courteous, on time, and clean! I initially asked for an estimate – I provided photos and got an estimate quickly which was reasonable. It was so easy! They came to our house the next day and all is well. Thank you Shanahan’s! I highly recommend them. A+++
