Shanahan's HVAC, Plumbing, Electrical & Remodeling, LLC repair two of our AC units (one unit had stopped cooling) that had rodent nests in both units. Izaiah diagnosed the issues with both and made the repairs within an hour on a Sunday afternoon (there was no extra charge for weekend service call). Very pleased with the repair service and will definitely use C.D. Shanahan’s the next time we need HVAC repairs/maintenance.Posted on Google Lia MelakouTrustindex verifies that the original source of the review is Google. Mr. Clarke was very professional and ensured our unit was properly serviced. Highly recommend this company.Posted on Google TraceyTrustindex verifies that the original source of the review is Google. Alex just came out and cleaned my condenser coils. He took his time and did a great job. Very pleased.Posted on Google Melissa WolpertTrustindex verifies that the original source of the review is Google. C.D. Shanahan's is an amazing company, family owned. We have used them to replace a hot water heater as well as a new AC/furnace. Our AC went out on a Thursday and I called them first thing Friday morning. The receptionist was amazing. She had someone there to me by that morning for a full diagnostic. Come to find out the compressor was bad. It would've cost half of a new unit to replace it. Our unit is 13 years old. Therefore, we decided it was best to replace the unit completely. Mike came that evening gave us pricing and I had estimates from two other companies. However, I decided on this company because of their reputation, the product, and timeliness. They were able to come and install the very next day. The owner himself came and installed the unit. They were incredible, very responsive and very accommodating. We have two children, so it was wonderful having the AC back so quickly! Use them, you won't regret it!Posted on Google Craig GoheenTrustindex verifies that the original source of the review is Google. I found out that there are at least 7 HVAC companies that say they provided 24/7 emergency service. C.D. Shanahan's is the only company that delivered on that commitment, Brandon arrived on time and got my A/C up and running properly in less than an hour. In addition to the repairs he gave me an eye opening education on MERV filter ratings. C.D. Shanahan's is now on the top of my list (only one company) of HVAC service companies i'll call in the future. UPDATE - 2 years later. My Lennox 2.5 ton unit failed (just over 12 years old). I called C.D. Shanahan's (along with 5 other companies) and got estimates for a total replacement. C.D. Shanahan's gave me a credible estimate for a new Trane. I had to wait 4 days for an install, and C.D. Shanahan's loaned (at no charge) a portable room A/C so we could sleep in some comfort. On install day the team showed up, installed the new unit and we were up and running. Dan (the lead installer) made sure all the lines were tested, and fixed, and all the wiring was done correctly and the new thermostat was working.Posted on Google Ingrid SoTrustindex verifies that the original source of the review is Google. We had an excellent experience with C.D. Shanahan’s Heating, Cooling & Plumbing. Duncan came out within an hour of our call, quickly solved our immediate plumbing problem. He was prompt, knowledgeable, professional, and straightforward. We especially appreciated that he did not try to upsell us or recommend services we didn’t need-he simply explained what was happening and what actually needed to be done. That kind of honesty and expertise is incredibly valuable. We’re very glad to have found a locally owned small business we can trust and will absolutely be committed customers going forward. Highly recommend Duncan and C.D. Shanahan!Posted on Google David WhiteTrustindex verifies that the original source of the review is Google. So far, I am extremely impressed by the visit with Izaiah. He was already familiar with my condo billing, and the very unique set up that we have. He was knowledgeable and immediately put my mind at ease and was able to answer all the questions that I had. Excited for them to do the new install.Posted on Google Doug KupersmithTrustindex verifies that the original source of the review is Google. Shanahan’s continues to be the best in the area. I chose them to install a completely new system based on how well they’ve cared for my old system over the years. For the new purchase, Mike explained all their systems and options to me to help me come to the best decision for upgrading my house. Then Dan and Jose came in a couple days later and installed the completely new system in a few hours, cleaned everything up, and explained to me how to operate the new system. Top notch and professional support all around. That’s why I will continue to choose Shanahan’s for all my HVAC support.Posted on Google Corina VillegasTrustindex verifies that the original source of the review is Google. I was extremely satisfied with the the crew that Shanahan sent to install my new A/C unit. They were responsive, professional, polite, and efficient. Truly a great crew and great company. Also, I did some price comparison and I honestly felt I got the most bang for my buck having decided to go with Shanahan. I don't anticipate needing HVAC services again soon, but won't hesitate to call them if I need plumbing, electrical or remodeling done.Posted on Google RobertTrustindex verifies that the original source of the review is Google.
