National City's Trusted HVAC & Plumbing Experts

National City is a compact, diverse South Bay community with deep roots and a housing stock that reflects decades of San Diego’s growth. Many homes were built in the 1940s through 1970s, with aging plumbing and HVAC systems that need experienced, honest service professionals. The city’s bay-adjacent location provides moderate temperatures, but older homes with poor insulation and outdated equipment can still struggle with comfort and efficiency. Since 1952, ASI has been serving hardworking South Bay communities like National City with the expert care they deserve.

Whether you live near the Mile of Cars, in Paradise Hills, the Sweetwater area, along Highland Avenue, or anywhere in the 91950 zip code, The White Glove Guys arrive on time with fully stocked trucks. We service all major brands and never charge extra for nights, weekends, or holidays.

Heating Services

Heating Services

National City's bay-adjacent location keeps winter temperatures relatively mild, but many older homes in the city have poor insulation and aging furnaces that struggle to maintain comfortable temperatures on cold, damp nights. ASI's factory-trained technicians can repair or replace your heating system with honest advice about the most cost-effective solution for your specific home.

Air Conditioning

Air Conditioning

While National City's coastal proximity keeps extreme heat at bay, summer afternoons can still climb into the low-to-mid 80s, and homes without proper AC or with aging units can become uncomfortable quickly. Many older National City homes have window units or aging central systems that waste energy. Our technicians can help you find a more efficient cooling solution.

Plumbing Services

Plumbing Services

National City's predominantly older housing stock means aging plumbing is widespread. Galvanized pipes from the 1950s and 1960s, corroding copper from the 1970s, and outdated water heaters are common finds. ASI's licensed plumbers specialize in the plumbing systems found in older South Bay homes and provide straightforward pricing on every repair.

Sewer & Drain

Sewer & Drain

Older sewer laterals in National City are susceptible to root intrusion, pipe corrosion, and joint failure. Many homes still have original clay or cast iron lines. ASI uses HD camera inspections to assess your sewer line's condition and offers repair solutions ranging from spot repair to trenchless relining—always with upfront pricing.

Water Heaters

Water Heaters

Many National City water heaters are aging right alongside the homes they serve. Hard water and years of service take their toll, leading to reduced efficiency and eventual failure. Our plumbers will honestly assess whether a repair or replacement makes more sense and handle the job professionally either way.

Indoor Air Quality

Indoor Air Quality

National City's proximity to the 5 freeway and the port means traffic and industrial particulates can affect indoor air quality, especially in homes with older, leaky ductwork. ASI offers filtration, duct sealing, and air purification solutions that help National City homeowners breathe cleaner air at home.

Michael Griffin, with ASI, called prior to arriving, arrived on time, and promptly and thoroughly checked all of my plumbing systems. He tested my water for mineral content and assured me that my soft water system was functioning well. He cleaned out a clogged pipe and made recommendations for continuing care for faucets and drains. He took several pictures which he reviewed with me. He alerted me to possible concerns with my aging water heater and helped to set up an appointment with a specialist. He was professional and personable, receptive to questions and informative with answers, attentive to needs and easy-going in all conversations. I hope he can return for future service calls!
