Having an HVAC system helps your home remain comfortable regardless of the weather outside. Many homes already have this type of system in place, but they may need to be upgraded or even replaced at some point. It is important to know what you want in an HVAC unit and also how to keep it maintained. This advice will be of help.

If your HVAC system us giving you issues, take a look around the house prior to calling a contractor. Jot down the rooms that are hot and the ones that are cold. Give this information to your contractor when they arrive.

Make certain that an outdoor unit is in the shade. When your unit is bringing in cool air, it will not have to work as hard to cool the air as it moves it inside, boosting efficiency.

When you are no longer using your outdoor air conditioning unit, be sure to protect it with a tight cover. This will keep it free of debris, frost and snow so that you’ll have a working unit when the spring comes and you are ready to uncover it and use it again.

In the winter, wearing layers can save you a ton of money on your utility bill. If you can install a digital thermostat that makes the house cooler when you’re asleep and warmer just before you get up, you can see significant savings on your next bill when it arrives.

If you currently have a manual thermostat, consider installing a programmable one. You can set your system for different temperatures depending on time of day and if anyone is home. Also, you can set upper and lower temperature settings to allow for a comfortable range of temperatures so that heating and cooling don’t kick in when not needed.

A programmable thermostat is a simple way to help save money on air conditioning costs. A thermostat that’s programmable is going to save you around ten percent on the heating and cooling costs you have to pay when you turn it back about fifteen percent for a part of the day. Additionally, some models of programmable thermostats actually allow you to control them remotely from your office computer or cell phone.

Consider all of your alternatives before installing a central air conditioner. You can only cool certain rooms, use whole-house fans, or even make use of a geothermal system. The more efficient the system you set up, the less you’ll spend on utility bills over time as you use it.

To know how large of an air conditioner you need, look for a calculator online. While you might think that a larger HVAC system is always better, in fact, larger systems sometimes are not the best choice for a particular space. Check the manufacturer’s handbook to see what amount of space the unit can effectively cool.

An HVAC system makes it possible to keep your home at a comfortable temperature throughout the year, so it is an excellent investment. If you need to make repairs or replace your unit, remember what you’ve just read. You will make better decisions as a result.
