"Anyvision and Chase were excellent! Their bid was competitive, and their contract was clear and straightforward. What began as a simple shower pan repair turned into a full master bath remodel and a new roof due to water damage. Having dealt with poor contractors for 45 years, we feared the worst, but Chase handled everything seamlessly. He assessed the damage, adjusted the plan, and had the skilled crew to execute both repairs and high-quality finishes. The team was punctual, professional, and kept our home clean. Chase’s tile specialists did exceptional work—no metal edges, just beautifully mitered finishes. With the remodel being unexpected, we had to make quick decisions, but Anyvision’s designer and CAD renderings helped us visualize everything. Chase was onsite daily, keeping us informed with updates, photos, and videos. Challenges arose, but Chase managed them like a pro—offering smart design input, controlling costs, and maintaining quality. This was the best contractor experience we’ve had in the PNW. Anyvision is the real deal, and we’d hire them again in a heartbeat. Their communication, expertise, and customer-first approach set them apart"

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."

FAQs for swimming pool heaters installation and replacement projects in Bothell, WA

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.
