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

You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives). 

Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.

It’s a better use of energy (and your money) NOT to run an ERV system all the time. Most experts recommend that you cycle your ERV system on and off throughout the year. However, the recommended advice could change based on your climate, the number of people in your home, the size and style of your home, and your heating and cooling system. Contact a local pro for more specific advice.

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.

There are three main types of heat pumps. An air-source heat pump system is the most common and has two parts—an indoor air handler unit and an outdoor heat pump unit. A ductless heat pump system functions similarly to an air-source heat pump system but doesn’t need ductwork to distribute the air. A geothermal heat pump system pulls heat from the ground to help heat your home.

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.
