St. Louis Energy Audit

With increasing utility prices, energy efficiency is at the top of every homeowner’s mind. Would a home energy audit be helpful for you?

Apart from flaring energy bills, there are several other problems that can be a result of poor energy efficiency, and homeowners might not even realize it. If we break down a residential energy bill, the largest contribution is made by the home HVAC system. So, any effort to improve energy efficiency and bring down the energy bill should start with looking into the cost of heating and cooling your home. A good way to discover where and how your home is wasting energy is by way of an energy audit.

I’ve been using “THOMAS Hoffmann Airconditioning and Heating LLC” for years now. We have a 30 +\- year old system that works perfectly for us. Although we’ve not had to use it yet, it is comforting to know they offer a 24 hour on call service. I really appreciate that the technicians don’t try to upsell us on anything. They’re a very professional, knowledgeable, and courteous, local-family owned and operated business. I’ve also found their pricing to be very fair and by”fair” I don’t mean “cheap” but reasonable… especially for the quality of service provided by THOMAS Hoffmann HVAC. I love supporting smaller family owned business and this one is top-notch! Thank you guys!
Response from the owner:Thank you so much for your continued support and kind words, Mari! We truly appreciate your loyalty and are glad to hear about your positive experiences with our services. We look forward to continuing to provide you with top-notch service in the future.

0 stars if I could. Bought a faulty (not to mention overpriced) surface igniter, called back five minutes later after installing, of course they didn’t stand behind their part. Go to Grainger instead. Same (working) part, half the price.

A Home Performance Energy Audit

A home performance energy audit can be described as a comprehensive approach to identifying the main sources in your home that are making it energy inefficient, uncomfortable, and unhealthy. In other words, an energy audit helps identify the primary components that are adversely affecting the performance, comfort, and energy efficiency of your home.  An energy audit is advisable for homes that are experiencing any of the following:

  • High energy bills
  • Heating & cooling systems run constantly to maintain comfort level
  • Drafty rooms
  • Moisture on the windows
  • Significant temperature differences between rooms
  • Inability to maintain consistent temperature
  • Excessive dust
  • Cold floors in winter
  • Dry indoor air in winter
  • Peeling exterior paint

These are tell-tale signs that your home might be using energy inefficiently, and an energy audit might be necessary to identify problem areas. After conducting the audit, Thomas Hoffmann Air Conditioning & Heating LLC can recommend solutions to address any problems. An energy audit will help identify the most effective upgrades and home improvements that will offer several benefits.

Increased Energy Efficiency and Lower Energy Bills

An energy audit is conducted using specialized skills and tools and can help identify cost-effective measures to bring down the energy consumption in your home and, in turn, the energy bill.

Increased Home Value

Energy-efficient homes are much easier to sell and fetch higher prices in the market.

Better Comfort

Air leakage not only increases energy consumption but can also make your home environment unhealthy and uncomfortable. By sealing all leakages your home will become a lot more comfortable.

Protect the Environment

It helps decrease your carbon footprint.

Better Indoor Air Quality

By sealing all leakages, you can keep dust and other contaminants out and improve the indoor air quality considerably.

Identify Hidden Problems

There might be some hidden problems in your home, such as inadequate ventilation, which come to the fore during an energy audit.

A home energy audit is certainly a wise investment, as it pays for itself quickly in terms of lower energy bills, better home value, and improved comfort. Schedule an appointment with Thomas Hoffmann Air Conditioning & Heating LLC at (314) 471-7625 to conduct an energy audit of your home, and identify home improvements that will improve energy efficiency and add value to your home.
