Why Defective Installation Is a Growing Concern
Defective installation is one of the most common causes of property damage and safety hazards in California homes today. As homeowners increasingly invest in solar panels, HVAC systems, and complex electrical upgrades, the number of installation-related failures continues to rise.
At KAASS LAW, we’ve seen a surge in claims related to poor workmanship and substandard installations. These issues may not be visible at first, but they often result in significant property damage, health risks, or even fire hazards. This blog highlights the key risks, legal rights, and solutions available when facing a defective installation in your home.
Defective Installation in Solar Panel Systems
California leads the nation in solar panel installations, but not every job is done right. This can ruin a roof, cause leaks, or even create fire risks.
Here are a few signs of solar panel installation failure:
-
Water damage or roof sagging
-
Exposed or overheating wires
-
Poor energy output
-
Panels detaching from the roof
Often, these issues arise when contractors use low-grade equipment or fail to properly seal roof penetrations. In some cases, installers bypass electrical codes to cut costs or speed up the job. That’s when legal action may be necessary.
If your home has suffered due to negligent solar work, KAASS LAW is here to help you hold the responsible parties accountable and recover your losses.
HVAC Systems and Installation Problems
When HVAC systems are poorly installed, homeowners often suffer both financially and physically. A defective installation of a heating, ventilation, or air conditioning unit can lead to:
-
Mold growth from improper drainage
-
Unstable temperatures due to poor airflow
-
Frequent system breakdowns
-
Health risks from air contamination
Most HVAC problems stem from incorrect duct sizing, poor ventilation design, or improper refrigerant levels. These are all contractor errors, not user mistakes.
Because many homeowners don’t realize HVAC issues until months later, it’s important to document performance problems as soon as they arise. Our team at KAASS LAW can assess whether faulty installation is at the root of the issue and guide you on the next steps.
Electrical Hazards from Defective Installation
Electrical work is one area where defective installation can have life-threatening consequences. Faulty wiring, improperly grounded circuits, or code violations can lead to:
-
Electric shocks
-
Circuit overloads
-
Power outages
-
House fires
These risks aren’t just inconvenient—they’re dangerous. If you’ve recently had electrical work completed and are experiencing flickering lights, overheating outlets, or strange smells, you may be dealing with a serious issue.
Our attorneys work with forensic electricians to identify where and how the defective installation occurred and pursue claims against negligent contractors.
Legal Rights You Have
California’s Right to Repair Act (SB 800) gives homeowners the right to pursue legal claims when a defective installation causes property damage or safety hazards. This law applies to all new construction and remodels.
Before filing a lawsuit, you must notify the contractor and allow them an opportunity to inspect and correct the problem. However, many contractors deny responsibility or make minimal efforts to fix the issue.
That’s where KAASS LAW comes in. We’ll help you:
-
Send a proper legal notice to the responsible parties
-
Document the defect and its consequences
-
Negotiate or litigate for full compensation

Common Signs of a Defective Installation
In many cases, homeowners don’t immediately realize that something was installed incorrectly. Here are signs that may point to a defective installation:
-
Skyrocketing energy bills after new systems are installed
-
Visible leaks or warped surfaces near recent construction
-
Inconsistent room temperatures
-
Circuit breakers that frequently trip
-
Noise, odor, or poor system performance
If any of these problems occur soon after a project is completed, don’t ignore them. Save all invoices, contracts, and communication with your contractor, and contact an attorney to evaluate your case.
