With the amount of time you probably spent at home last year, you may have noticed your energy bills have gone up recently. Obviously, having your house serve as an office, school, and all-around entertainment hub doesn't help, but there are other things in your household that could be sending costs higher. Here are four simple tips to keep in mind to boost your home's energy efficiency.

1. Weather seal your household

Little cracks and holes in the attic could be running up your energy costs. You may notice your indoor air feeling chilly despite your heater running at full blast. All Weather Seal, a leading contractor, helps homeowners to make the renovations necessary to keep a home properly insulated no matter what time of year. For example, properly installed vinyl siding can help to better regulate the internal temperatures of a house.

Energy-efficient steel roofing is a durable solution in comparison to common roofing material. It's the best way to not only reduce your energy costs but also help your home withstand the elements. The installation of windows will not only promote greater ventilation but also provide a better weather seal for framing. This includes door jambs, where cold air can sneakily make its way into your household. 

2. Consider alternative energy options

With more renewable energy options being made available to homeowners, it's in their best interest to do electricity comparison research to be done to determine the right electric service for your household. For example, solar power generated from sunlight is captured through panels installed upon residential properties. This energy is converted to electricity and used to get air, water, and power homes.

In some instances, electric suppliers will offer discounted electricity rates for renewable energy platforms. In some countries, homeowners receive a tax credit for the installation of solar panels. More countries are inviting households to reduce their carbon footprint to address increasing environmental concerns. Striving to become carbon neutral is becoming quite popular in the corporate world no matter a company's size, and is now being approached on the homefront to help people put some ease on their electric bill. 

3. Invest in Energy Star appliances

Homeowners are encouraged to invest in Energy Star appliances, products endorsed by the United States Department of Energy and the Environmental Protection Agency for greater energy efficiency. These products range from air conditioning units to the refrigerator you have in your kitchen. For appliances like dishwashers, you're getting the best value long-term for your electric bill.

As for appliances where wires are accessible, it's best to just unplug them when possible, such as a countertop microwave. Consider Energy Star products as part of a home improvement project. While it may be an expense at its onset, the pros will be shown long-term for your bank account and spending on energy bills.

4. Repair your faulty systems

If you notice some bad smells in your home, you could have some issues with your home's HVAC system. For example, if you're dealing with an odor of rotten eggs, this could be indicative of a gas leak. Exit your home immediately and contact your gas company as well as a technician to evaluate your home for any troubles with natural gas. Another tip to stop bad smells is to open up windows for more ventilation to improve indoor air quality. 

If the smell is mustier, you could be dealing with mold and mildew. If your home's humidity level is outside a range of 40 to 50 percent, you are essentially creating a breeding ground for mold growth. It's important to keep the vent pipe on a heating system clear of any obstruction, to prevent musty smells and any issues from accruing with an HVAC unit.
