HVAC Questions From Property Owners in DeLand, FL

Why does my home feel humid even when the AC is running?

This often indicates your system is not properly removing moisture. Oversized equipment, airflow issues, or maintenance problems can reduce dehumidification performance.

How long should an AC system last in Florida?

Due to frequent use, most systems last around 10–15 years. Regular maintenance can help extend lifespan and maintain efficiency.

Is it normal for my AC to run most of the day in summer?

In hot climates like DeLand, longer run times are common. However, constant operation could indicate inefficiency or system issues that should be evaluated.

Can upgrading insulation improve HVAC performance?

Yes, better insulation helps maintain indoor temperatures and reduces strain on your HVAC system.

What are the benefits of a maintenance agreement?

Maintenance plans help catch issues early, reduce repair costs, and keep your system running efficiently throughout the year.

Air Conditioning Maintenance in DeLand, FL 32720

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.
