"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."

Brooks Heating & Air is dedicated to providing the best cooling, heating and air solutions for your home or business. If you need air conditioning or heating services from a well-established HVAC company in Northern VA, call Brooks Heating & Air for reliable heating and cooling services. We will keep your comfort in tune! *Previously known as BVSM Heating & Air Conditioning. Same great people, same great service.*

"Brooks replaced our near-30-year-old Trane heat pump that died on us. Their price was better than the other companies we contacted and they were also able to do the work sooner than those companies. They were professional in all aspects of the installation and we were extremely happy with their work. Unfortunately, an issue arose with the heat pump months later (through no fault of Brooks) and we needed to have the coils replaced. Brooks went above and beyond to fix the problem to our satisfaction, arranging for Trane to send new coils and then replacing them at no cost under their 1-year labor warranty. Brooks provided a 2-hour arrival window for the start of service and sent an email notifying us that the service technician was on his way, including his name and picture. The service technician was professional, knowledgeable, and friendly and the heat pump was working perfectly when he left. Brooks gets our highest rating and recommendation."

"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."

Energy Efficiency Auditing questions, answered by experts

The three levels of home energy audits include:

  • Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.

  • Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.

  • Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.

Motion-sensor lights use one watt while on standby and five watts while turned on. They’re usually on for one hour over a 24-hour period, bringing the total wattage to about 28 watts per day. LED lights use around 6.5 to 8 watts while on. If you leave an LED light on all night, with night ranging from 10 to 14 hours, you’re looking at using 65 to 112 watts a night. You can minimally cut your wattage in half by switching to a motion-sensor light.

Insulation is measured by R-value, which is the measure of a material's ability to resist heat transfer. The higher the number, the better the insulation. When installing insulation yourself, you need to determine the optimal R-value you need to keep your home warm in the wintertime, cool in the heat of summer, and energy-efficient all year long. Each inch of insulation provides between a 3 and an 8 R-value. The climate where you live plays a major role in what R-value you need and the price tag you might see in your insulation installation.

No, it isn’t necessary to have energy-efficient windows. However, if you care about your energy bill and making your windows more energy efficient, fixing any heat, UV, or air transfer issues is an excellent way to lower your bills and keep your house cooler in the summer and warmer in the winter.

R-value is calculated by dividing the thickness of an insulation material by its thermal conductivity. The material's composition and density influence thermal conductivity. Materials with lower conductivity values provide better insulation. The higher the R-value, the better the material is at insulating, helping homeowners select insulation that meets the energy needs of their climate and home layout.
