Our HVAC unit completely shut down. A diagnosis by another HVAC company determined that the compressor was bad and needed to be replaced. I was provided quotes for replacing the compressor and the air handler. I called Garrison & Garrison for a second quote on a new unit. A company sales representative, Carl, worked me in on short notice. Upon his arrival, I explained the problem and diagnosis by another company. Looking at the unit and making a couple of quick tests, he demonstrated that there was nothing wrong with the compressor and the problem likely was a short in the air handler. I asked if he could schedule a diagnostic assessment before I made a decision on the purchase of a new unit. Carl and Josh arrived the next morning to conduct a second assessment. In less than 3 minutes they pinpointed the problem (it was a short in the air handler), made repairs and the system was back up and cooling just fine saving me thousands of dollars in replacement cost. It is my personal observation and experience that these two representatives of Garrison & Garrison demonstrated the highest level of technical expertise, professionalism, honesty and integrity. I highly recommend this company. Garrison & Garrison is now my go-to company for HVAC services.read more

I dealt with Garrison and Garrison today for the first time, Nick the technician was professional, went directly to check the system without wasting time, and before fixing what he thought was wrong consulted with his supervisor (quality control), in less than half an hour the AC was working fine.I do recommend Garrison and Garrison for dependability, no nonsense honesty, and reasonable pricing.I should have known them earlier, they are very good. Thank you.read more

Nick Day with Garrison and Garrison came out as a call back on another techs previous regular maintenance call. There was an issue that was not discovered, Nick, with some investigation diagnosed our problem, which was a small leak in the air handler coil. Now that we know what the issue is and our options are we can make an informed decision. Nick was very thorough and professional. Thanksread more

Even though the unit itself, which was an American Standard, was only 10 years old Roberto, Juan and Nick, our installers, did an exceptional job in the replacement of our old unit. Roberto was professional, and his utmost concern was the safety of our household. Roberto, Juan, and Nick did an excellent job on the installation and it was completed as quickly and efficiently as possible. I would recommend Garrison & Garrison at any time to others.read more

Josh and the rest of the team provided excellent customer service as well as prompt repair of our HVAC system. The subcontractor our builder hired to install the system did a terrible job and refused to fixed their mistakes. We called G&G who promptly came out, diagnosed the problems, including parts that weren’t up to code then sent an entire crew to fix everything.Honestly, we cannot say enough good things about this company. Keep it up!read more

The entire team did a great job. Our unit failed on a Wednesday, and we had a written estimate within a few hours after calling. The new unit was fully functional less than a week later. The project was complicated by a challenging landscape, requiring a new pad, and additional duct work to accommodate the larger unit. The team worked well together, communicated throughout the day, and did excellent work. Thanks Roberto and Nick!read more

I had two old American Standard units that I wanted to replace with newer ones which used R-454B as a refrigerant. David did a walkthrough of my property and provided an initial cost estimate. When the units became available, Carl followed up with a final proposal. The work was scheduled the day after we signed a contract and was completed in a timely manner over a two-day period. Beau and Cooper installed the systems. They arrived on time, were extremely courteous, worked very hard, cleaned up after they finished, provided me with documentation and manuals, and Beau walked me through the operation of the new thermostats. I felt that the staff was knowledgeable, honest, and straightforward. Everything went smoothly and I couldn’t have asked for more. Good job!read more

G & G did it again. I used then in my previous home when I needed to replace my old worn out unit and used them again for replacing a dead, cheap builders grade unit in my new home. Beau and Brent were the installers and they were superb. Everything went smoothly including having to build a new stand for the unit because of differences in size from previous unit. Everything was cleaned up before they left and made sure that I was happy with the new unit and the quality of the service. They arrived on time and were done about an hour earlier than estimated. Great job!read more

The absolute best! We had another company come out and diagnosis thousands of dollars of work. Their temporary fix was completely wrong. The technicians at Garrison & Garrison came out, took their time, and found the faults that were causing the non-functional system. I am telling everyone I know about this ethical and professional company. I really appreciate honest companies.read more

Noticed my HVAC unit was short cycling. Tried a reset but no improvement. Knowing this problem could end up damaging the compressor I called Garrison & Garrison for help. They sent a Tech out a couple hours later. He found a couple parts on the unit had failed. The parts were ordered and he came back out and installed them. The unit is now working perfectly. All I can say is great professional job all the way around! Kudos to the Garrison & Garrison team!!!!!read more

Recently I called Garrison and Garrison to have my HVAC unit inspected as there seemed to be humidity and airflow inconsistencies. Josh, our technician, who was referred to me by a family friend, gave a thorough inspection. He was professional, friendly, and honest when it was aparent that the issue was caused by a setting on the thermostat. I will definitely call on him again when I need the unit serviced and inspected and have already recommended him to other family members. It’s invaluable to have found an HVAC tech I feel confident and trusting of.read more
