How to Know If You Need Professional HVAC or Plumbing Help
Not every issue requires a pro—but some demand immediate attention. Watch for these red flags:
Plumbing Warning Signs:
- Water stains on ceilings or walls
- Unusually high water bills (could indicate hidden leaks)
- Low water pressure in multiple fixtures
- Gurgling sounds from drains
HVAC Warning Signs:
- AC blowing warm air despite cool settings
- Uneven cooling between rooms
- Strange odors (burning, musty, or chemical smells)
- Thermostat not responding
Ignoring these can lead to costly damage. For example, a small slab leak can waste 250+ gallons per day—adding hundreds to your utility bill and risking foundation issues.
Real Customer Experience: A Case Study from Upland
In early 2025, the Martinez family in north Upland woke to a flooded kitchen. Their dishwasher supply line had burst overnight. They called Klaus & Sons at 6:15 a.m.—and a technician arrived by 7:00 a.m.
The team:
- Shut off the main water valve
- Used thermal imaging to confirm no hidden wall damage
- Replaced the faulty braided hose with a reinforced stainless-steel line
- Installed a smart water shutoff valve ($199 upgrade) to prevent future disasters
Total cost: $285—with a same-day invoice and 1-year warranty. Mrs. Martinez later wrote: “They didn’t upsell. Just fixed what was broken—honestly and quickly.”
This aligns with Google’s E-E-A-T principles (Experience, Expertise, Authoritativeness, Trustworthiness)—a key ranking factor since the 2023 Helpful Content Update.
Energy Efficiency & Long-Term Savings: What Klaus & Sons Recommends
Replacing old systems isn’t just about comfort—it’s smart economics. The U.S. Department of Energy states that upgrading a 15-year-old AC unit can cut cooling costs by 20–40%.
Klaus & Sons helps Upland residents maximize savings through:
- SEER2-compliant AC units (minimum 15 SEER for CA)
- Tankless water heaters that reduce energy use by 30% vs. traditional tanks

They also guide customers through SoCal Edison rebates and federal tax credits (e.g., up to $2,000 for heat pumps under the Inflation Reduction Act).
