It's unbelievable but some companies required upfront deposit even before assessment of the issue.

Prices are horribly high now everywhere,but plumbing can't be avoided,so their price point is adequate to area,but service is superb.

We pushed off the replacement thinking our unit would survive one more winter, but of course of furnace went out unexpectedly in the middle of the night during one of the coldest stints of the season. Called Residential Express the following morning, they pulled up my quote from 4 months prior, verified the price hadn't changed and were able to schedule me for a full HVAC replacement the next day. Freddie and Flavian arrived on time and were very professional moving through our house and working in our backyard and utility closet. They explained any changes they needed to make, went over the new setup and recommended service intervals, and hauled all of the old equipment away, leaving our house looking better than when they arrived. Very happy with our experience with Residential Express and wouldn't hesitate to use them again.

This review is based on recent experiences with customer service representatives/admin folks. So it was during calls to the main number, and we reside in Virginia. We recently had a very expensive repair for a hot water heater that severely damaged our circuit breaker box. So the techs came out, did their thing and were phenomenal. However, in order for us to submit the repairs for reimbursement with our home warranty company, we require an itemized invoice. As per the egregiously rude phone reps we have encountered, there is a company policy against itemized invoices. Like, WHAT!?! I have never experienced anything like it in the history of working with service providers. There is always an itemized invoice. However, that in itself is not the issue. First, my spouse spoke to someone who said that it is only possible to obtain by escalating to a manager. So we waited and attempted to follow-up. Each time after we both tried to follow-up, we encountered some of the rudest, most unprofessional individuals on the line. Not to mention, AGAIN, how does it make sense that you are doing work of this magnitude and cannot produce an invoice that breaks down parts and labor!?! I am certain that this isn't the first time in history that the company encountered this kind of request when customers are dealing with insurances and warranty companies. It is wholly disappointing, when you consider that the individuals in the field doing the labor intensive work can be overshadowed by the policies of the company. I literally have no idea what to say at this point, but that we will be transitioning to Michael & Son's or another provider. Because who wants to pay this kind of money to be mistreated on the backend for something as simple as an itemized invoice. Such a shame!

This is my second time using BlueStar and I have nothing but amazing things to say about them. The…read morefirst time they fixed my furnace which had build up on a sensor which was an easy fix. John came out and was very straight forward and up front with everything he did. He explained the issue to me, how he would fix it, and even provided some recommendations I may want to do in the future. My second time I used Bluestar was on a Sunday and they are closed on Sunday's. I did not realize this at first and left them a voicemail in the morning. Realizing they were closed I called another company who would have charged me more than Bluestar to come out later that afternoon to look at the problem which was that my Nest Thermostat was giving an E73 error code meaning it was not getting power. To my surprise I received a call from John at Bluestar that afternoon prior to the other HVAC company coming out. I discussed my thermostat issue not getting power with John and he suggested several troubleshooting fixes I could try over the phone. After eliminating several causes of what the problem may be John suggested holding down the front panel cover switch to the unit to see if a power light was coming on. In doing this I noticed sometimes the light would come on and sometimes it would not. There seemed to be a loose connection in the a wire that was causing the switch not to supply power. After playing with the switch for a few minutes I got the power to stay on and the problem was fixed. John solved my problem and saved me a good deal of money as I canceled my appointment with the other HVAC company. John took over 20 minutes talking to me on the phone going above an beyond to help me solve my AC issue on the day the company is closed. I would highly recommend BluStar to anyone and will use them for all my future HVAC needs.

Before he left asked if I need to pay next time while replacing part. He very clearly said there would be another labor $100 cost for me. Then he contacted me for replacement part within day, and he offered $400 for the item. I checked the replacement part price from online stores, it was never $400 at any store, and I found the same part with $150 price. Then I let him know not to order for the part, instead, I would order it. Now, the replacement part is ready and this company is requesting $250 for labor fee which we already discussed. Moreover, they are changing their speaking as if it was about distance of location. What is funny my home is pretty close to their location around 15 min most. Their behavior is not ethical, and I am not stupid. Briefly, if you want to spend more money in than regular cost , you can go with them.
