Protect Your HVAC Investment with a Surge Protector!

Storm damage to your home can come in multiple forms, and one you may not think about is the damage to your HVAC.  Owners Renee and Travis learned firsthand: so busy taking care of other peoples’ homes, they didn’t make their own home a priority and have a surge protector installed. All it took was one lightning strike to take out their communicating thermostat and furnace circuit board. Since they had a variable speed, communicating system, these components are costly to replace. And, since this type of damage wasn't covered under warranty (and the rest of their system was out of warranty), they ended up having to replace their entire system.

In Indianapolis, where weather conditions can be unpredictable, ensuring the longevity and efficiency of your heating and cooling system is paramount. At LCS Heating and Cooling, we understand the importance of safeguarding your HVAC investment against unexpected power fluctuations or surges.

Regular AC maintenance is an often overlooked aspect of homeownership, but its importance cannot be overstated. By keeping your air conditioning system clean, well-maintained, and functioning efficiently, you can improve your overall comfort, save money on energy bills, and extend the life of your system. Trust our professionals at LCS Heating & Cooling to provide you with thorough AC maintenance services, ensuring that you can stay cool and comfortable all summer long.
