**Update 08-25-26** Our second service appointment on 08-13-26 was again very satisfying. Ken & Erick did a thorough job, and we're happy to know our unit is still hanging in there during this hot summer. I had concerns about our room vents, and Ken ordered replacements for all of the "common area rooms". The price was reasonable, and they returned yesterday to install them. Already, the airflow is so much improved, and they look great. Our LR and kitchen were so much cooler yesterday, just by being able to adjust the flow, which we couldn't do with the older construction grade vents. We now plan to order vents for the bedrooms and bathroom to be installed at our next service appointment. Ken & Erick are a great team, and real assets to your company. They were friendly, professional and explained everything so well. They took time to make sure we were satisfied with everything. We are so pleased that we made the switch, and I look forward to working with them for ALL of our HVAC needs. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 2025: We have recently changed our HVAC service provider to JACOB, from another company (who I will not name, because they were actually pretty good over the years). We contacted Jacob for a second estimate after our existing company recommended replacing our unit (it was working fine) due to age and deterioration. We were with our previous company since 2016, and while our unit was in great running order, they were wonderful about keeping our AC "maintained" at a fair price. As the years went on, they started high pressure sales pitches to add features, upgrades and finally a whole new unit... (ours is now 13 years old, but running fine). When we told them we were going to get a few quotes before deciding, the other company went into high pressure mode with scare tactics, which we did NOT appreciate. Alex from JACOB came out to offer a second quote for the cost of a new unit. He was about as low pressure as you get, and he instilled confidence. I didn't feel under any pressure to buy a new unit and he presented great info on maintaining and replacing our unit. In fact, he agreed with us, that as long as it's working fine, there is no urgent need to replace it. We liked their quote, and decided that if we did need to replace the whole unit, JACOB had the better quote. My husband and I discussed everything, and we decided to change our maintenance plan to JACOB now, and when our unit finally "dies a natural death", we will merely grab an updated quote and go with JACOB. So we had our first maintenance appointment a few days ago with Jabin and Sam. They were prompt, professional, courteous and even offered some great tips to help maintain our unit. I think we made the right decision.
Response from the owner:Thank you, Rose, for sharing your detailed experience with us! We're glad to hear that Alex provided you with a low-pressure approach and that Jabin and Sam impressed you during your maintenance appointment. Your satisfaction means a lot to us, and we appreciate your trust in our team.

Fabulous service. Called with a thermostat issue and they came out that same day. Resolved the issue quickly, no fuss no bother. Jacob has been a very reliable service that I’ve had for many years and will continue to use.
