Reviews of local pros in Chantilly, Virginia

Friendly staff but they won't sell to anyone who isn't contactor with an "account"

Delivered coils here and everyone was courteous and professional. Lot kind of tight but have definitely dealt with worse.

Drivers are going to kill somebody on the road. I suggest you check, recheck credentials, then train, and train some more. Swerving lane to lane without checking blind spots and nearly running drivers off the road. This is unacceptable.

Don't bother going there if you are a "lowly" homeowner trying to save some $ by doing things yourself. They won't sell you anything without an account. Jerk policy.

These guys treated me really well, I thought that I needed a fan motor but didn’t, and even tho it was A nonreturnable part as I didn’t have an account, they still allowed my return without making it a big deal. They really impressed me with the way they handled it, as we all as customers dread bad encounters. I will definitely give them my business again when the need arises.

The person that unloaded the bundles of insulation from my trailer needs more training in counting offloaded product. Arrived at next stop with 16 extra bundles, and I know it wasn't a shipper miscount.

Courteous, friendly, and competent staff.

Mark and George helped us out in the back end of a heat wave and did great work

Excellent company. They have serviced our home for at least ten years.

After the initial visit, I have been waiting for over 3 weeks for their reports. The do not have the decency to return any of my calls or to say the will not provide service.

Placed a call through my Home Warranty and at first they must have forgotten about me but then a very nice man called me back saying he can have someone at my home within an hour. Happy.

Great company to work with! They have done extensive work in our home and we have been thrilled to have them. Will, lead technician, has been a pleasure to to deal with!

This is the worst AC company I have ever come across. They have not been able to fix our ac for almost a year now. Every time they come they say everything is fixed, after two weeks the AC stops cooling. Today they came and promised they have fixed it and now our ac is not working at all. Do not work with this company. They will constantly screw your system and they have no clue what's going on. They have the worst customer service

They were able to schedule a convenient appointment, they arrived as expected, did furnace inspection and all was at the price they quoted. Imagine a service provider showing up when they say they are going to, do what they say they are going to do and for how much they say they were going to do!!

If you have an A/C or Heating problem you should call Residential Systems. They were extremely pleasant on the phone and took care of my issues very quickly. All the technicians were very pleasant and helpful explaining what was wrong and what they did.

This contractor is HORRIBLE and unresponsive. They have a contract with warranty companies and they never call to setup appointment. Warranty companies need to terminate their contract with these clowns and find a better company. We can make this happen, if more people complain. RSI, GET YOUR ACT TOGETHER!

Great experience. Warranty company sent them out so we expected the worst but the service and professionalism was stellar. Of course they did what the warranty company made them do ,the absolute minimum, but at least we knew it was done right. We will keep them in mind for our next service even when we cancel our home warranty

We have this service call placed and they did not call and did not answer my calls. They called to schedule after the HW company follow up and set up 4 hour wait window. Indeed they don't value customer, customer time and urgency of the issue. There is no heat and its winter time. Definitely the warranty company should drop them from their contractor list.

This company is absolutely awful. RSI charged my mom for a coil and a TXV valve for her indoor air handler at the same time they installed a new heat pump. Come to find out they did not install the coil and TXV valve that she paid for. The heat pump they sold her was not compatible with her indoor air handler. They refused to answer her calls for weeks and will not remedy their mistake. She has had to replace the entire system.

This company must never have a customer service person working at their store because they never ever pick up the phone. If you make a claim through your warranty company good luck in getting these guys to call you and make an appointment. You have to call and call them to get them to come out and continually follow up otherwise they will never show up. If you are able to get them to show up they actually get the work done for the most part.

The experience I had with Residential Systems was just fantastic. The A/C tech "Chris" who came out and did the work was very professional, friendly and just very approachable whenever I had a question. You could really tell he knew what he was doing analyzing and working on our non- functioning condenser issue.This was not a simple fix on a failed unit but Chris performed the work in an efficient manor with a step-by-step diagnosis of our failed condenser. He basically got the cool air flowing in the house again with the condenser fan running. At the end of the day, which I didn't consider that long and well worth the reasonable price. I would highly recommend anyone in need of Heating and A/C work, to use them.

There aren't too many honest and hard working A/C contractors out there these days, so it was very refreshing working with Residential Systems. Thank you for your prompt, courteous and thorough service.
