What Command Service Center is About

Attic insulation

Attic insulation is one of the number one reasons homeowners have electric bills they find hard to handle. If you do not have enough insulation in this area of your home, you will be colder in the winter and hotter in the summer. If you have no idea what type of insulation you have in the attic, call Command Service Center Inc to take a look and give you an estimate to make your home more energy efficient. Don't wait any longer; you can begin saving money today with proper insulation in your home. You can feel the difference in Comfort.

Heating and Air conditioning needs

When you begin thinking about your heating and air conditioning needs, you may be confused by all of the products available. You need to speak with someone who can explain the differences and the pros and cons of all of the units. Indoor air quality is a main concern of many families. People with allergies need to be especially careful and purchasing an appliance that will help with air quality may be the answer. If you just purchased a home, you may need to ask about affordable options and when certain appliances will need to be replaced. Talking with a professional you can trust will make all of the difference.

Sump pump and Humidifier

In Northern Cook county you probably own a home with a basement. If you have ever experienced a flood in this room of your home, you realize the need for a sump pump and even a humidifier. This is a great area to live and you can enjoy all the seasons of the year. Making sure you and your family are comfortable should be a number one priority. Using the basement for additional living space may be important for a growing family. If you know what you need, but you are not sure where to find it, contacting a reputable heating and air conditioning company will help. Installing a sump pump is not exactly a do it yourself kind of job. You will probably need to dig up a spot in the basement and run electrical if it is not already available. Let the professionals do the job for you and begin enjoying your basement again.


Buying a home in eastern McHenery County can provide you with opportunities for entertainment and adventure. Although one of the adventures you may not be interested in are those occasional power outages that occur at the worst possible times. If you have lived through this experience in the past, think about purchasing generators to provide the power you need when you need it. Whether you want to supply your entire house or if you will be satisfied with enough energy for the fridge and television, Command Service Center will give you exactly what you need.

Water Heater and other appliances

If you are thinking about other appliances or even a new water heater, make sure you compare prices and find the best deal. Purchasing one of the new water heaters will not only save you money, but could provide you with more hot water when you need it. If your teenage daughters enjoy daily bubble baths, don't get stuck taking a cold shower because the hot water heater can't keep up. When you are choosing the best products you also need to consider the customer service and warranty available. Working with a hometown company like Command Service Center, you will feel comfortable spending the money and knowing you are getting a deal on price and service.
