My husband and I have spent a lot of time consulting with an architect. After living in our cramped, starter home for the past 11 years, we were finally ready to make some needed changes to it. We have added an extra 600 square feet of space onto our house. Before the construction began, we finalized the plans for our new heating and air conditioning unit with our HVAC contractor. Because our home was going to be substantially bigger than it is now, we purchased a larger HVAC system. We also installed a new, digital thermostat inside my home. On this blog, I hope you will discover the best types of HVAC units to buy for mid-size homes. Enjoy!
It doesn't matter how much you spent or the brand you bought, air conditioners can't run without flaws for the rest of your life. There will be times that the systems need recharging. Here are the signs to look out for, so you can recharge and get the cool air back as soon as possible.
1. The Unit Is Blowing Warm Air
When the unit starts blowing warm/room temperature air, it is a sign the system needs recharging. You will be able to test this by placing your hand over the vent for a short period of time to check feel the difference. The thermostat readings will also tell you if there is a change. If you're going to check by placing your hand over the vents, SF Gates suggest waiting 15 minutes from when you turned the unit on to give it chance to drop the temperature enough.
2. Check the Thermostat Is Working
Before jumping to the conclusion that the unit needs recharging, it's important to make sure the thermostat is actually working. Reset the thermostat and check again. This is especially important if you feel cool but the temperature gauge tells you something else.
3. Dirty Unit
Check the unit for any dirt and debris. Clean all the filters and replace any that are damage. A dirty unit can give off some of the same signs as it needing to be recharged. Dirty units can also lead to future problems, so you should keep up to date with this form of maintenance. When you've cleaned the unit and it's still blowing warm air, you'll need to get it recharged.
4. Check for Coolant Leaks
Rather than needing recharged, the unit may be leaking coolant. You'll find frost building up where the leaks are, and sense the same problems of warmer temperature blowing through. If you recharge your unit with leaks, you'll suffer the same problem later. The frost build-up can also lead to damaged fan motors, tubes, and more within the system.
The unit can't just use up the refrigerant or coolant. If someone tells you it's been used up, it means there is a leak somewhere.
Fixing the unit is something that you can do yourself at home. However, it will depend on the problem. If you feel out of your depth and unsure about problems, it is best to call commercial HVAC contractors who have experience with your business cooling system.
