"The company deserves 1000 stars l. Chris came and gave a well thorough inspection and estimate of my actic. Had my concerns and expectations, I had several other companies come and give quotes for double the price. Especially ORKIN. Orkin tried to use care tactics to sign contract without any explanation. Chris gave the quote and the crew arrived a week later as scheduled. Chris has a great work crew who were professional , caring, and did high quality work. Every step of the way, I was communicated and was filled in. I was shown before , during and after photos. And end results were UNBELIEVABLE Chris is fair and honest, he gives reasonable prices and will not take advantage of his customers."

"I had a new electrical line I wanted to run for a display light attached to a grandfather clock in our foyer. I also requested a switch be added to our wall panel by the front door to operate it. The job involved seeking a route for running wire behind the ceiling and drywall from our basement to the first floor of the house. The installation was complicated and obviously required a healthy amount of expertise in all respects. The work was accomplished with a minimal amount of mess (two small holes) and the quad switch panel added by our front door operates flawlessly. During the same visit they also replaced four decorative ceiling light fixtures and repaired a bad electrical outlet to boot. The workers were fast, efficient and friendly (even to my dog). I can't say enough about this company to do this justice. Very satisfied with my decision to give them a call."

In the summer of 1977, Don Hoffacker's Air Conditioning & Heating opened its doors to begin providing residents in Montgomery County with quality service and installations of new heating and cooling equipment. The firm seeks to employ only qualified individuals, who are continuously educated and trained on new products arriving on the residential market each year. We pride ourselves as a firm having been recognized time and again by local media, as well as a very prominent consumer organization, as a business providing service and installation procedures which are top rated for both price and quality.

"I was a loyal customer of Hoffacker's for 30 years and had been very satisfied. Unfortunately, my latest experience with the Hoffacker's team was horrible and I won't use their services going forward. The technicians were great. But the pricing ($450 for 40 minutes of service in my home) seemed very high. When I called to request a clarification for the charge, the service manager was rude, disrespectful and did not follow up when he promised to do so. On my third call back to discuss the issue with him, he rudely told me that the company does not want me as a customer and would take me off their customer list. I have never experienced anything like this in any customer service encounter (on any front). Rude. Disrespectful. Horrible customer service. Especially to a loyal, 30 year customer. I won't be giving them business going forward. And would never recommend them to any of my friends."

"We had a great experience with Bethesda Systems. Jay came out to our house shortly after we requested a quote, asked what we were looking for, thoroughly investigated how to install what we needed, and then provided a detailed quote that gave us options of what speakers we could choose from and where to install them. The quote covered three areas and we ultimately chose just to install outdoor speakers. The actual installation process was done professionally and expertly with minimal hassle for us, but with a complete explanation of how to use Sonos. All in all, we are very happy customers and would use Bethesda Systems again."

"Avoid at all cost. Don't even get HomeServe home warranty cuz that's what they use. They came and fixed the leak by replacing the toilet ring/rubber. During the process, they caused a leak between the toilet tank and toilet bowl and refused to take responsibility saying they didn't touch the toilet tank. They actually did. I watched them when they used a water suction vaccuum to get dry out the tank. Also they had to unscrew the bolts connecting the tank and the toilet seat. When putting those bolts back they didn't do it right and the leak is where the bolts connecting them. Yet they said they didn't touch it. Wow. We are currently looking at actions (perhaps a small court claim) that we can take against them. Just found I can file a complaint on Department of Professional and Occupational Regulation which is where all the licenses are granted. Perhaps contact City rep too. Im going to wait and see if this gets resolved first."

Energy Efficiency Auditing questions, answered by experts

Installing weather stripping or upgrading to insulated panels can improve efficiency.

Audits typically take 2-4 hours, depending on the property size and energy systems.

Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.

Some types of electric fireplaces use more electricity than others. Models that produce 1,500 watts will have more of an effect on your heating bill than 750-watt models. 

Electric fireplaces use an average of $1.85 of electricity every eight hours. These minimal operational costs aren’t likely to make a big difference in your electric bill—unless you’re using it as a primary heating source for your home and it’s running most of the time.

Gas fireplaces use either natural gas or propane—both of which will increase your energy expenses. On average, running a gas fireplace costs $400 to $640 per year; however, these costs can vary significantly depending on the fuel price in your area and the frequency of fireplace use. If you’re looking for a more energy-efficient option, consider switching to an electric fireplace.
