As a homeowner, your biggest investment is likely your house. As you continue to maintain your home's heating and plumbing system, you will save lots of money and time on repairs. It is important to not only check out your system's periodically, but create a set schedule that will help you avoid neglecting it. 

Quarterly

Your home's air filters should be checked at least every 3 months. A lot of this depends on the conditions in the home. If you have pets or susceptible to allergies, then you are going to want to change it much sooner. You can purchase higher efficiency filters that will last much longer and only require you to replace them about twice a year. These can be more expensive, but do not need to be purchased as often to help offset the cost. For more information, check with companies like ac by Marino's Plumbing & Gas Fitting.

Clean your shower heads every few months to ensure you are getting the most water possible. This can be done easily using vinegar to clean them. Simply soak them in a bag of vinegar to remove an dirt, debris, or rust that could clog them up. You will see how much more water you will get after a good cleaning and eliminate a face full of bacteria infested water once you have cleaned off the shower head. 

Biannually

In order to ensure your heating system runs most efficiently, you need to check your water heater pressure valve at least twice a year. Minerals and corrosion can quickly buildup on it and cause it to malfunction or spring a leak. The temperature and pressure relief valves can help reduce a dangerous amount of pressure building in your unit. In order to make sure it works right, you need to test the lever. This includes raising it up and down several times so that the brass part lifts up.You should see some hot water come out of it and into the drain or else the valve needs to be replaced. 

The refrigerator coils in your refrigerator system can get clogged with dirt and debris. The best way to keep your refrigerator running efficiently is to vacuum the coils. This helps remove any clogs so air can pass through freely. You could end up saving up to $100 a year by doing this quick and simple task. You want to be careful you do not use too much suction to damage the coils. A small handheld vacuum will do just the trick.
