Common Misconceptions That Affect Winter Comfort

What San Diego Residents Get Wrong Every Winter

When winter rolls around in San Diego, many homeowners fall for winter HVAC myths that suggest their heating and plumbing systems don’t need much attention. As cooler mornings and evenings continue into January, this mindset often leads to avoidable breakdowns, higher energy bills, and uncomfortable homes.

As a trusted San Diego HVAC company and provider of local plumbing services, we see the same winter HVAC myths year after year. Let’s clear them up and help you keep your home running efficiently all season long.

Winter HVAC Myth 1: Heaters Don’t Need Maintenance in San Diego

One of the most common winter HVAC myths is that heaters don’t require regular maintenance in a mild climate.

Even in San Diego, heating systems work hard during colder mornings and evenings. Without regular maintenance, small issues can go unnoticed and turn into costly repairs right when you need heat the most.

The truth: Annual heater maintenance improves efficiency, helps prevent unexpected breakdowns, and extends the life of your system. San Diego winters may be mild, but your heater still deserves attention. According to ENERGY STAR’s heating and cooling efficiency guidelines, proper system care plays a major role in performance and energy savings.

Winter HVAC Myth 2: Air Filters Only Matter in Summer

Another popular winter HVAC myth is that air filters only affect cooling performance.

Many homeowners forget about their air filters once cooling season ends.

The truth: Filters matter year round. During winter, heaters circulate air throughout your home just like air conditioners do. A dirty filter can restrict airflow, reduce efficiency, and worsen indoor air quality. ENERGY STAR recommends routine filter checks as part of maintaining clean and efficient heating systems.

Tip: Check your filter monthly and replace it as needed, especially if you have pets or allergies.

Myth 3: Closing Vents Saves Energy

This winter HVAC myth sounds logical but often does more harm than good.

Most HVAC systems are designed to distribute air evenly. Closing vents can increase pressure in the system, reduce efficiency, and strain components, leading to higher energy bills and potential damage. HVAC industry experts consistently note this as a common misconception that can negatively affect system performance.

Better approach: Keep vents open and talk to a professional about zoning options or airflow adjustments if certain rooms feel uncomfortable.

Myth 4: Plumbing Problems Only Happen in Cold Climates

Not all winter HVAC myths apply only to heating. Plumbing misconceptions are common too.

While frozen pipes are rare in San Diego, winter still affects plumbing systems. Colder temperatures can reveal leaks, slow drains, and water heater issues. Increased indoor water use during winter also puts added stress on plumbing systems.

Tip: Pay attention to changes in water pressure, slow drains, or inconsistent hot water and address them early.

Myth 5: If It’s Working, There’s Nothing to Worry About

One of the most costly winter HVAC myths is assuming that no visible problem means no risk.

Many HVAC and plumbing issues start small and worsen over time. Regular inspections help catch problems early, improve performance, and reduce long term costs.
