Most homeowners know when it’s time to replace and upgrade their heating and AC systems—about every 15 to 20 years, depending on the system and maintenance care over the years. But do you know when you need to replace your thermostat? Generally speaking, the thermostat should be replaced each time the heating/cooling system is replaced. The thermostat is the primary system responsible for controlling the HVAC system—which means that the efficiency rating and size of the unit won’t matter much if its thermostat is unreliable or faulty.
In a nutshell—no.
Yes, it’s summertime in south Florida and it’s much hotter and more humid than during the rest of the year, which means your system will likely cycle on and off less often—but, your system should not be struggling to keep up. If your air conditioner is constantly running and not reaching the targeted temperature, there’s something wrong with your system.
Summer is nearly here, which means you need to ensure your AC unit is running as well as possible—and if it’s not, then you need to decide if installing a new unit is your best option. Here in south Florida, it feels like there are two seasons: hot and hotter. During the hot summer days (and nights), you’re air conditioner runs constantly and works hard to keep your home cool. If you find your electricity bills are increasing but it takes longer for your unit to cool your home, installing a new high-efficiency air conditioner is likely the way to go, and there are many benefits to choosing a high-efficiency unit over a “standard” one.
Like any other big ticket item, buying the right HVAC unit requires that you do a little research before deciding on the type and size that’s the best fit for you home and your needs.
