Short, honest guides to the three things that break most often — so you can spot trouble early and hire with confidence.
HVAC
Warning signs
- Rooms that never reach the temperature on the thermostat
- Energy bills climbing with no change in habits
- Short cycling, rattling, or a burning smell at startup
Typical cost
Repairs typically $150–$800; a full system replacement usually $5,000–$12,000.
Ask your pro
"How old is my system, and is repairing it worth it versus replacing?"
Roof repairs
Warning signs
- Curling, cracked, or missing shingles after a storm
- Water stains on ceilings or in the attic
- Granules collecting in the gutters
Typical cost
Spot repairs often $400–$1,800; a full replacement usually $8,000–$20,000.
Ask your pro
"Can this be patched safely, or is the underlayment already compromised?"
Plumbing
Warning signs
- Slow drains in more than one fixture at once
- Water pressure that drops without explanation
- Discolored water or a water heater past 10 years old
Typical cost
Common fixes $150–$600; water heater replacement usually $1,200–$3,500.
Ask your pro
"Is this an isolated fixture problem or something in the main line?"
