A Clarksville Homeowner’s Guide to Pre-Vacation HVAC Prep
The excitement of an upcoming vacation is a feeling like no other. As you finalize your itinerary, pack your bags, and make a checklist of last-minute tasks, your focus is understandably on the journey ahead. In this flurry of preparation, it is easy to overlook one of the most important systems you will be leaving behind: your home’s heating, ventilation, and air conditioning (HVAC) system. How you prepare this critical appliance before you leave can have a significant impact on your energy bills, the health of your home, and your overall peace of mind while you are away.
Properly preparing your HVAC system is a crucial step in securing your home. A few simple, strategic adjustments can prevent wasteful energy consumption, protect your property from the risks of unchecked humidity or freezing temperatures, and ensure you return to a comfortable and welcoming environment. At Barney’s Heating and Air, we believe that a truly relaxing vacation starts with the confidence that your home is safe and sound. This guide will walk you through the essential steps every Clarksville homeowner should take to prepare their HVAC system, so you can leave your worries behind and fully enjoy your time away.
Don’t Turn Your System Completely Off
One of the most common and tempting mistakes homeowners make is to turn their HVAC system completely off before leaving for vacation, believing it is the best way to save money. While the logic seems sound, this can be a very costly error, especially given our region’s distinct seasons. Your HVAC system does more than just control the temperature; it also manages your home’s indoor climate and humidity levels. Turning it off completely leaves your home vulnerable to the extremes of the Tennessee weather.
During a hot and humid Clarksville summer, turning off your air conditioner allows heat and, more importantly, humidity to build up inside your home. This creates a hot, stagnant, and moist environment, which is the perfect breeding ground for mold and mildew. This can lead to a musty, unhealthy home upon your return and can require expensive remediation to resolve. High humidity can also cause significant damage to your property, causing wood floors, doors, and furniture to swell and warp, and even harming sensitive electronics.
The risks are just as significant during the winter. Turning off your heating system completely can allow the indoor temperature of your home to plummet below freezing during a cold snap. This puts all the plumbing pipes within your walls at a high risk of freezing and bursting. A burst pipe can lead to catastrophic water damage, turning your return from a relaxing vacation into a devastating and incredibly expensive disaster. The goal of vacation prep is not to eliminate your HVAC’s function, but to control it intelligently.
Finding the “Vacation Sweet Spot” on Your Thermostat
The correct approach is to set your thermostat to a safe, energy-efficient “away” temperature that will protect your home without running unnecessarily. For a summer vacation, we recommend setting your thermostat to a temperature in the range of 80 to 85 degrees Fahrenheit. This is high enough that your air conditioner will likely only run during the absolute hottest parts of the day, which will save a significant amount of energy. At the same time, it is low enough to keep the indoor humidity below the threshold where mold and mildew can thrive, protecting your home and your air quality.
For a winter getaway, we recommend a setting in the range of 55 to 60 degrees Fahrenheit. This is low enough to provide substantial savings on your heating bill but high enough to ensure the internal temperature of your home and your walls never drops to a point where your pipes are at risk of freezing. This simple adjustment is a crucial insurance policy against water damage.
The easiest way to manage these settings is with modern thermostat technology. A programmable thermostat can be set to a “Hold” or “Vacation” mode, which will maintain your chosen away temperature for the duration of your trip. The ultimate tool for peace of mind, however, is a smart thermostat. These Wi-Fi-enabled devices allow you to monitor and adjust your home’s temperature from a simple app on your smartphone, from anywhere in the world. This means you can check in on your home during an unexpected heatwave or cold snap, and you can even begin to return your home to your preferred comfortable temperature as you are on your way back from your trip.

Check and Change Your Air Filter
Before you leave, it is absolutely essential that you perform a quick, five-minute task that can protect your entire HVAC system: checking and, if necessary, changing your air filter. Your system will still be cycling on and off periodically to maintain your set vacation temperature, and you want to ensure it can do so as efficiently and safely as possible. The air filter is your system’s first line of defense, and leaving a dirty, clogged filter in place while your home is unoccupied is a significant and unnecessary risk.
A clogged filter severely restricts the airflow your system needs to function properly. This forces the blower motor to work much harder, which not only wastes energy but also puts a major strain on the component. This restricted airflow can lead to two of the most common causes of a system breakdown. In the summer, it can prevent enough warm air from passing over the indoor coil, causing it to freeze into a solid block of ice. This will shut your system down completely and can lead to a major water leak when the ice block eventually thaws. In the winter, the same lack of airflow can cause your furnace to overheat, tripping a safety limit switch and leaving you without any heat to protect your pipes. This simple, inexpensive task is the most effective thing you can do to protect your multi-thousand-dollar investment.
A Pre-Vacation Professional Tune-Up
While the steps above are excellent practices for any homeowner, the single best way to ensure your home is fully protected while you are away is to schedule a professional preventive maintenance visit before your trip. A pre-vacation HVAC tune-up is the ultimate insurance policy for your home comfort system. It provides you with the complete confidence that your equipment is in peak condition to operate reliably and efficiently while your home is unattended.
During a professional tune-up, a certified technician from Barney’s Heating and Air will perform a comprehensive, multi-point inspection and a series of services that go far beyond what a homeowner can do. We will thoroughly clean the indoor and outdoor coils to ensure maximum efficiency. We will test all of the critical electrical components, like the capacitors and contactors, to make sure they are strong and not at risk of failing under stress. We will also inspect and clear the condensate drain line, which is one of the most common sources of a vacation-timed water leak.
This professional check-up is designed to identify and resolve any small, developing issues before they have a chance to turn into a major failure while you are gone. It is a smart, proactive step that can save you from the immense stress and expense of returning home to a broken HVAC system and a potentially damaged house. Scheduling this service before your trip is one of the best ways to ensure your vacation is truly worry-free.
