Reviews

What customers say

Customers praise thorough troubleshooting and respectful service, citing repeat checks after clogs in two faucets and a technician's investigation of a boiler vibration followed by system cleaning. One customer reports being urged toward a “Platinum” service while arranging a pump replacement and questions the workmanship and warranty handling.

Customer Reviews

Christina Coulling

Bobby was completely professional and took care of the clogs in the kitchen and bathroom faucets.He repeatedly checked both to make sure that by pressing the problem out of one, it didn't interfere with the second. He was very thorough with checking everything from the hot water tank to the plumbing, all the pipes, valves, faucets, everything. He took the time to make sure the problem was fixed correctly. Would highly recommend them for any of your plumbing needs.

Michele Smith

Joe was very respectful. He thoroughly checked out boiler to find where the vibration noise was coming from. He cleaned out the system. He said the noise was coming from the fan but that is working fine. He said he would us a quote on a new part if we wanted to replace it. Very happy with the way he worked

Be Your Own Unique

Rob came to our home and made this process so much easier on us. We were sold a "lemon home" and legit nothing we can do other than just fix it up. Even tho the price was high (no fault to the company, ALL the fault to the builders) we are 100% focused on using this company to do the work. Didnt bull-ish us. Came in quick, thoroughly and was very respectful. Look forward to working with them.

Today I got a new furnace installed. I was very pleased with the work Elvis and Juan did. These guy's worked very hard and diligently. I appreciate their knowledge and professionalism. Everything was explained to me thoroughly. Their demeanor was pleasant even when I needed them to explain what they just had explained to me again. I want to give special thanks to Demetrius Wheeler of Michael and Son who got the ball rolling. He explained the process of the installation and also helped me with additional financing needs. Once again my experience with Michael and Son has been outstanding. Thanks again guy's cause I'm 100% a Michael and Son fan.

Frustrating Experience: Pushy Sales, Price Hikes, and Sloppy Work If you’re considering Reliable Home Services, I strongly recommend asking a lot of questions—and double-checking any work they perform before the 30 day warranty is up (Beware you maybe labeled argumentative and told so lol). Also, something else to consider. Even if they do a good job, would they respond kindly, respectfully, and with your interest in mind? Rob the dispatch would say as he has said to me, "It's up to the customer to decide". Also, would they be argumentative and fully honor a warranty? My guess is that there would be additional "platinum" recommendations - see some of the 1, 2, and 3 star reviews and judge for yourself. That's what happened to me - see details below. If you’d like more details or want to see photo evidence of what was (or wasn’t) done, feel free to check the attached images or DM me directly. I’m more than happy to share so others can make an informed decision. My issues started with Rob, the dispatcher. I had previously used the company for a full system refresh and even left a 5-star review, so I expected a similar experience (deleted the review because I couldn't post this one). This time, I called about replacing a pump that had already been diagnosed by them, but I had delayed service due to financial timing. When I called back to schedule, Rob gave me a push for their $2,200 “Platinum” service, even though much of that work had already been done a year prior. When I questioned the need for it, his response was basically, "It’s up to the customer to decide." The whole conversation felt more like a used car sales call than home repair. What really crossed the line, though, was when Rob said he would note in their system that I was being "argumentative"—and that everyone would see those notes. That was uncalled for, especially considering I was just asking questions about pricing and service relevance. Unfortunately, things got worse when the technician arrived. The first thing he said to me—before even assessing the job—was that the owners didn’t want to do the job. No explanation, just a strange and inappropriate comment that instantly made the whole situation feel tense and uncomfortable. Then came the pricing issue. I was originally quoted $650 in May 2025, but when the tech showed up in July, the quote had jumped to $800. When I questioned the $150 increase, I was first told it was due to rising parts costs. Then, the explanation changed: due to how AC units are manufactured, now the company recommends full replacements over repairs, even though only my pump was broken. It felt like an obvious upsell tactic or that Rob, the dispatcher, was sticking it to me for being "argumentative". When I asked the technician to call the office to check if the original quote could still be honored, he flat-out refused. He told me I could “take it or leave it.” No effort to make a simple phone call. No interest in advocating for the customer—just dismissiveness and attitude. Despite all of this, I agreed to move forward with the service because I needed the pump replaced. But due to the overall tone and behavior, I didn’t trust the quality of the work. So I inspected the installation myself afterward—and I’m glad I did. The pump was missing a critical clamp included, clearly shown in the product’s instruction manual. Without it, the system will likely leak again. So i'll just go and buy the clamp and fix it myself. (See attached photos.) At the end of the day and to the technician’s credit, he did apologize for how the interaction started, and the job ended on a more cordial note. But that doesn’t erase the pushy sales tactics, the unprofessional tone, or the incomplete work (see a few of Reliability Home Services 1 - 3 star reviews and you'll start to see a pattern). Reliable Home Services is not what it used to be. I won’t be using them again—and if you do, proceed with caution. Ask questions, read the fine print, and check the work yourself within the 30 day warranty.
