The team at Millions custom landscaping has over 60 years combined leadership experience. We do all phases of landscape installations. From drains, Irrigation,lawns, flower bed, water features, night lighting, rock walls, block walls, and Patios to mention a few. We also install decks, and fences.

"James Millions presented himself as a General Contractor that would take on the full project. We specifically told him we were looking for one contractor to fulfill every trade - even if that meant subcontracting out. In the end, that's not what happened. They sent us emails, "we don't have anyone to do that - sorry about that". Their communication was lacking - pretty much only email - a day or so later. Several times, they were on vacation and not reachable by us or their crew that was onsite. The site crew was fantastic. The site lead did everything he could to get the project completed, to best of his crew's ability. In the end, we had to manage the project by finding many other trades people to finish the job. What was supposed to be a small project, has been delayed because James' oversold his ability/desire to be the General Contractor of our job."

Swimming pool heaters installations and replacements FAQs

Yes, you can add a pool heater to an existing pool. Many homeowners install a pool heater during pool remodels to enhance their overall pool experience. Heaters offer various advantages, such as consistent and precise temperature, property value boosts, and more opportunities to enjoy swimming regardless of weather conditions.

No, a pool heater doesn’t need to run all the time—instead, most homeowners use the heater to raise and maintain the temperature as needed during use. Pool heaters require between 24 and 72 hours to fully heat a pool, so you should prepare and run it well ahead of time. If you plan to use it frequently, use a pool cover to retain heat and reduce energy consumption.

Pool heaters can freeze if left exposed to extreme conditions. Freezing can damage internal heater components, potentially leading to costly repairs. Cycling water, covering the heater, and regular maintenance servicing 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 heater lifespans vary depending on the type of heater and maintenance, but they can last between seven and 30 years. Gas and propane furnaces have the shortest lifespans, about seven to 12 years, while electric and solar pool heaters can last up to 30 years.
