Bryan, unlike other folks who gave me an estimate, took time to talk with me, explain everything in detail, and was available as needed throughout the project. He has also been great about promptly providing the names of good companies for other needs I had, i.e. a plumber or someone to check out possible water damage. The crew were prompt, polite, and very patient with my questions throughout the process, as was the office staff. I would not hesitate to hire this company again!"

Hi folks. My name is Rakim and I and my son Charles own and operate this company together and are blessed to be given the opportunity to do so. I am a N.A.T.E. certified Master Tradesman and a father of 8. I'm training my son in the HVAC trade and on how to be successful while operating a business with integrity. Charles is a graduate of Monacan High School and J. Sergeant Reynolds Community College and has been in the trade for several years now. I have worked for a few of the largest and smallest HVAC companies in the area over the years and I know everything they are doing right and what they are doing wrong. We get it. We believe we can do a better job at service and keep the price more reasonable. So far we have proven that to be true. We are so sincerely appreciative of you helping us grow and being a part of our success story.

"Did a very good job."

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."

"Ripped off. I was hopeful of having a good experience, since a friend referred me to this company, but that didn't happen. My A/C fan was constantly running, but not cooling. They came out and said it needed a capacitor, and that it would be $405. I agreed, thinking it was an expensive part and he needed a good amount of time to do the job. It took 45 minutes tops (he also cleaned the screen on the sides and checked the filter "for free".). He didn't leave me with a receipt, so I asked for one, and he emailed it right away. It was NOT itemized, and so there was no way to know how much they charged/hr., or how much the part was. I looked up the part online, and guess what...about $10. So BUYER BEWARE. When I called the office for information about hourly costs and the part cost, she said what another reviewer reported upon his call: that there is a flat fee, etc. Oh, and there's a $15 charge for their gas, since prices are so high, and to keep their "fleet mobile and ready to serve." The only positive part is that my AC is working, and the technician was very nice, but I WILL NOT BE USING THIS COMPANY AGAIN."

Heating Oil questions, answered by experts

Costs depend on system age, type, labor, and whether part replacements are necessary.

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.

DIY maintenance like filter cleaning is possible, but professional servicing ensures proper pressure, refrigerant levels, and loop performance.

Service costs range from $200 to $1,500, depending on maintenance needs, system age, and labor.

If a geothermal heat pump is installed correctly, then you shouldn’t have to worry about having a backup heat source such as a furnace or oil boiler. However, there are geothermal systems installed that include a backup in case the heat pump fails due to extreme cold. This is simply a backup heat pump you’ll likely never need and not an alternative heat source.
