Can you Run Your AC and Heat at the Same Time?

can you run your ac and heat at the same time

As temperatures begin to rise, you may wonder if you can run your AC and Furnace at the same time? In short, yes you can switch back and forth between the two on the same. However, there are some precautions you will want to take in order to make the switch safely.

How To Safely Switch between Heat and AC?

Weather can be a bit unpredictable as the seasons change and it can become tricky to keep your home at a comfortable temperature. It makes sense that you will want to use your heater when it’s cooler in the morning and AC when it warms up later in the day. By learning how to safely switch between the two, you will prevent high energy bills and extra strain on your system.

It can be tempting to quickly switch from heating to AC without putting too much thought into it. However, it is this sudden change that causes damage to your system. It is important to always wait until the current cycle has finished before switching. If you were to switch while the system is still cooling, the outdoor unit works a lot harder to warm up the house again putting extra wear and tear on your system. Also, avoid extreme temperatures boosts, because cranking up the thermostat will not change the temperature any quicker.

By taking care of your HVAC system you will help avoid high energy bills and costly AC repair or heating repair. Remember it takes time for the temperature in your home to adjust, after you have switched, be patient with the process.

Schedule Routine HVAC Maintenance

It is best to refrain from switching from heating to air conditioning to a minimum. But, one of the steps you can take to make sure alternating between your AC and furnace goes as smoothly as possible, is to keep up to date with HVAC maintenance. A properly maintained HVAC system will last longer and perform more efficiently than a neglected cooling and heating system. Replace your air filters regularly, dirty clogged air filters restrict air flow which causes both systems to work harder than necessary.

Furthermore, routine maintenance helps prevent issues such as stretched fan belts, frayed wiring from wasting energy or leading to costly repairs. If either system is not performing like it should contact a professional HVAC technician right away before it gets worse and leads to a complete breakdown. Keep in mind that at some point, all HVAC systems will require maintenance, repairs, or replacement. It is important for you to do your part in scheduling routine maintenance visits to prevent minor issues from turning into costly repairs or leading to early heating or AC replacement.

Invest in a Smart Thermostat

If you do not already have a smart thermostat in your home, install one so you can easily adjust the temperature in your home while saving money on your energy bills. With features such as remote access and automatic scheduling, smart thermostats can be adjusted based on various factors such as outdoor temperature and whether or not someone is home. This will help cut unnecessary consumption to save you money.
