Thanks so much for taking the time to look into Air Nerds as your last stop in searching for the right HVAC contractor. The owner, James Martin is a 3rd generation HVAC nerd. His father would take him on jobs when he was a kid and tear the work down - making James redo it if it was incorrect. Even in crawl spaces, where no one would see the work. Air Nerds believes in putting ourselves in the shoes of the homeowner who pays the bills. The owner's father taught him the value of honesty and hard work over high-pressure sales and rip-offs. When you choose Air Nerds you can rest assured that our highly skilled team of certified HVAC nerds will enter your home carrying tools and the same principles of business.

"I called James on Monday, he came out, diagnosed and removed the gas valve from my 21 year old furnace. While diagnosing he explained how and why everything worked. He offered to loan me a couple of space heaters for the night. I declined as I had my own. He came back Tuesday with a new valve and I have heat again. He is very knowledgeable, professional, and personable. He takes pride in his work. If I have any HVAC issues in the future Air Nerds will be the first place I call."

Commonwealth Energy Systems opened for business on April 6, 1999, but we were not the new kids on the block. The owner, Stephen Smith, and eight key employees had all worked for the largest window and siding company in Central Virginia and had a combined experience of over 170 years in the home improvement field. We all had learned that just selling a quality product was not enough. Even the best product is not satisfactory if it is not installed properly. We pride ourselves on the very best window and siding installers who only work for us. It is much more cost effective to do the job right the first time. Much of our business is obtained by referrals from our satisfied customers. We do have a service department, because some things are unavoidable such as glass breakage. When service is required, we do it in a timely fashion. We are proudly celebrating our 15 year anniversary.

"I Paid $5,300 to install and put in a brand new system, including all parts according to Henry Briggs Property management. Less than a year later, they go back out there without my permission and install a new capacitor saying that was bad and they didn't install a complete new system. They charged me over $700 to work on the inside air unit that they said they now didn't replace. I'm going to need this resolved pretty quickly. I am going to go take pictures, find out what else was not done that I paid for on the last installation. I'm not happy, this is not okay. "

Energy Efficiency Auditing questions, answered by experts

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.

Absolutely! Especially if you have an older home that currently doesn’t have air conditioning where installing ductwork just wouldn't work. No one likes being hot in the warmer months, so if you’re looking to sell your home in the near future, installing a ductless mini-split AC can be a good way to enjoy your home more while you’re in it, boost the return on your sale, and serve as a perk to peak buyers’ interest.

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

Yes, skylights can affect a home’s energy efficiency, either positively or negatively. Properly installed, energy-efficient skylights with Low-E coatings, double glazing, and UV-blocking glass can help regulate indoor temperatures and reduce heating and cooling costs. However, poorly insulated or older skylights can contribute to heat loss in winter and excess heat gain in summer, lowering overall energy efficiency.

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.
