"Initial rep was great and informative. Felt comfortable with initial sale. Hardly had any contact from customer service except for the payments. There were several delays that we were not informed about unless we called to ask. Took 7 months before they showed up to begin project. Only 1 person was sent to build steps. Took a week. Hard worked, hardly took a break. Had to call again to see when they would come to pour patio. Never knew when they were coming, they just showed up. Hardly spoke with the homeowners. Inspection paperwork was just left on porch. Additional paperwork that is "required by the County" had to be completed by homeowner and taken to Court house to be notarized and filed and also provide a copy back to Long Fence.

Gave this contract to LF on the surface of their history and appearance of a 'good local company' but should have stayed with original contactors in VA. Puddle of water forms when it rains"

For over 35 years, American Home Contractors has provided exterior household services and upgrades across Maryland, Washington DC, and Northern Virginia. American Home takes great pride in ensuring customer satisfaction and commits to delivering the highest quality of work when renovating any home.

"Signed contract for AHC to install exterior trim around my home and replace soffit vents. Costs were proposed for the trim wrapping and we informed AHC that we would also want to address the ventilation through soffits around the home. Initially we discussed adding vinyl to soffits, but were unsure of best options. We had then decided against moving forward with the project until we could conduct more research of the best options. AHC informed us that with the trim work they could also replace the damaged vents in the soffit. AHC said that the owner of the company had agreed to add this service for us as we had recently completed another project for the replacement of gutters. Upon the crew coming out to start work we informed them that the scope of project included the installation of exterior trim and replacement of vents. The crew said they had no information on replacing any vents and told us to call their office for clarification. I called AHC, and was informed that the crew could not replace the vents, but asked if they could repair damages noted. While we were not happy that the scope of work had changed, we agreed to have them repair and not replace the vents. However, after the project was completed we noticed that no work had been performed to repair any vents. We called and emailed AHC multiple times over a 2 month period to have them make adjustments to noted problems with trim and repair vents. We could not get anyone to give us an update on when the crew would come back out to address the trim and vents issues noted. AHC only sent a person out to fix gutters that had not been properly reinstalled and causing heavy flooding in backyard and to fix one item on the list of items for the trim. Again we compromised, and then decided to only focus on the vent repair. Many months went by before we received an email regarding a final invoice; and the company not being able to repair or replace the vents. Discounts were offered to accomodate us regarding the matter. We had no idea on how much it would cost to have a contractor come out to only fix vents, as opposed to adding to an existing job where cost could be different because the contractor is already onsite working other jobs on the home such as the install of trim. While continuing to work on getting additional quotes to have some other contractor fix the vents. AHC changed their minds and said they would not provide any discount. So basically, the initial job was to replace vents, then changed to repair vents, then changed to provide discount, then changed to we cannot help you. This is really bad customer service and we would have never agreed to have them take on the project as they clearly understand that we wanted both the soffit vents and exterior trim addressed at the same time. As we have gutters with guards and the work would require removing gutters to get to soffit, so we thought it was best to address both of these items at the same time. Agreeing to terms of a contract with the idea that you will not provide the services agreed upon is bad business. Also, we are not happy with the number of hours I have had to dedicate to trying to resolve this issue with AHC. We have used Angie's list for almost 10 years and never encountered this type of situation with one of your contractors. We only selected this company because they were listed as an Angie's List company."

"I'm a relatively new homeowner, so after a storm damaged my roof, I had no idea how to get my roof repaired or how to navigate the home insurance claim nightmare. I was so grateful when my friend's husband (who is a contractor specializing in home insurance jobs) recommended I call a company local to me called American Custom Contractors. My friend's husband told me he had worked with the company previously and knew that the company had good people, does good work, and is trustworthy. I'm happy to say that he was 100% right. Initially, my home insurance company only wanted to pay to replace a few shingles on my roof, but American Custom Contractors advocated on my behalf, and we were able to get the home insurance to replace my whole roof! There was months of back and forth with the home insurance company, but American Custom Contractors really allayed my anxiety during this whole process. In fact, everyone I met and spoke to at the company knew exactly what they were doing and were polite and professional. I felt like I was in good hands during the entire process. I'm happy to say my roof is now brand new and beautiful. I highly recommend American Custom Contractors for their superb customer service and high quality work."

FAQs for swimming pool heaters installation and replacement projects in Potomac, MD

Yes, you can add a heater to an existing pool. A pro can retrofit a heater to nearly any in-ground or above-ground pool. Adding a heater allows you to start the swim season earlier, finish it later, and maintain a steady water temperature in between. Many owners schedule the job during a larger pool upgrade, but it also works as a standalone project. Professional installation ties the new unit into the existing pump and plumbing for safe, efficient operation.

Most owners switch the heater on a day or two before they plan to swim, then shut it down afterward. Reaching the target temperature can take 24 to 72 hours, depending on pool size and outdoor conditions. Using a cover while the heater is off helps hold the heat and keeps energy costs in check.

Pool heaters can freeze if left exposed to extreme conditions. Freezing can damage internal heater components, potentially leading to costly pool repairs. Cycling water, covering the heater, and regular maintenance help prevent freezing. Sealing or winterizing your heater also protects it during the season—this involves draining water from the heater and its components.

Pool heaters operate with lifespans spanning from seven to 30 years. Gas and propane models last seven to 12 years, while electric and solar heaters perform efficiently for up to 30 years. Consistent professional maintenance and routine inspections extend the heater’s life and improve its performance, ensuring a safe and reliable heating system for your pool.

Before hiring a pool heater installation contractor, conduct thorough research by reviewing online feedback and gathering recommendations from trusted sources. Contact multiple professionals to discuss pricing, request references, and understand the complete installation process. This careful evaluation ensures you select a qualified contractor who delivers high-quality service and a successful installation.
