Three generations of the Teemsma family have operated Ideal Plumbing Heating Air Electrical from Waring Road in Allied Gardens, San Diego, since Donald Teemsma Sr. and Barbara Teemsma founded the company on April 1, 1960. The operation holds CSLB #348810 and #191758 under C-36 plumbing, C-20 HVAC, C-10 electrical, and B general building classifications — a four-trade license combination that allows single-contractor management of plumbing, heating, air conditioning, electrical, and kitchen-and-bath remodeling projects without subcontracting. Donald Teemsma Jr. took over in 1994, expanding from the plumbing-and-heating origin into air conditioning and electrical service, and the Waring Road storefront that opened in 1962 still anchors the 92120 service territory today. The company's kitchen and bathroom remodeling division handles fixture layout, tile installation, and cabinetry coordination, a design-build scope that intersects with Danielle Interior Design & Decor in Allied Gardens for space-planning and material selection on larger renovation projects. Plumbing service covers re-piping, water heater installation, garbage disposal replacement, pressure-regulator service, backflow-device testing, and sewer drain cleaning, all built to current Uniform Plumbing Code specifications. HVAC work installs high-efficiency furnaces rated up to 98 percent AFUE alongside central air conditioning systems sized to the inland heat loads, where Allied Gardens summer temperatures run ten to fifteen degrees warmer than the coast. Electrical services range from panel upgrades and whole-house surge protection to lighting design and EV charger installation. The company won the 2023 Better Business Bureau Torch Award for Ethics in San Diego, was named a Nextdoor Neighborhood Favorite in 2021, and earned Best of Houzz recognition in 2020. Ideal sponsors the Allied Gardens First Fridays Summer Concert series and volunteers at Mission Trails Regional Park, maintaining a community presence in the neighborhood where the company was born. Post-remodel finishing work on walls, ceilings, and trim often brings in San Diego Painting to complete the restoration after plumbing, electrical, or HVAC access cuts through finished surfaces. The 838 building permits on file with the City of San Diego document over six decades of project volume across the residential neighborhoods between Waring Road, Zion Avenue, and the I-8 corridor.
