FAQ
Before You Contact Us
Here are answers to some of the most common questions we get.
If you need more information or a custom solution, our team is here to help.please contact us. Our consultants will gladly answer all your questions.
How much does it cost to call an electrician to repair damaged wiring?
The cost of repairing damaged electrical wiring depends on several factors, including the location of the problem, accessibility, the type of wiring installed, and whether the issue affects a single circuit or the home’s main electrical system.
Common signs of damaged wiring include:
- flickering or dimming lights;
- burning smells;
- warm outlets or switches;
- frequently tripped breakers;
- outlets that stop working unexpectedly.
At MAIRON HVAC & Electrical Services, we begin every electrical repair with a professional diagnostic inspection to identify the exact cause of the problem before recommending any repairs. This approach helps homeowners avoid unnecessary work and ensures the electrical system remains safe and code-compliant. A typical troubleshooting call to an electrician costs $250, which includes finding and repairing minor wiring damage.
The light went out in half of the house. What should I do?
If power has been lost in only part of your home, the issue is often related to a tripped breaker, a failed electrical connection, a damaged circuit, or, in some cases, a problem with the utility service entering the property.
Before calling an electrician, you can:
- check your main electrical panel for tripped breakers;
- reset any GFCI outlets in kitchens, bathrooms, garages, and outdoor areas;
- verify whether your neighbors have also lost power;
- check if any electrical appliances were operating when the outage occurred.
If resetting the breaker does not restore power, avoid repeatedly resetting it, as this can indicate a potentially dangerous electrical fault.
Our licensed electricians can quickly diagnose partial power outages, identify failed circuits, damaged connections, or service issues, and restore power safely and efficiently.
Lights flicker in one of the rooms. Why?
Flickering lights can have several causes, ranging from a simple loose light bulb to more serious electrical problems.
Common causes include:
- loose bulb connections;
- worn light switches;
- overloaded circuits;
- loose wiring connections;
- voltage fluctuations;
- aging electrical panels;
- utility service issues.
If lights flicker only when large appliances turn on, such as an HVAC system or microwave, your electrical system may require further evaluation.
While occasional flickering is not always dangerous, persistent or worsening flickering should be inspected by a licensed electrician, especially if accompanied by buzzing sounds, burning odors, or warm electrical devices.
At MAIRON HVAC & Electrical Services, we perform a complete electrical diagnostic to identify the root cause of flickering lights and recommend the safest and most cost-effective solution.
Is it necessary to do grounding in an old house at all?
Many older homes in California were built before modern grounding requirements were introduced. While an older electrical system may still function, a lack of proper grounding can increase the risk of electrical shock, equipment damage, and reduced protection from electrical faults.
Grounding provides a safe path for electrical current during abnormal conditions and helps protect:
- people;
- appliances;
- electronics;
- HVAC equipment;
- EV charging systems.
Whether grounding upgrades are necessary depends on the age of the home, the condition of the electrical system, and any planned renovations or equipment installations.
Our electricians can perform a comprehensive electrical safety inspection and determine whether grounding improvements or electrical upgrades are recommended for your specific property.
How often should I service my HVAC system?
Most HVAC manufacturers and industry professionals recommend servicing your heating and cooling systems at least once per year. For systems that provide both heating and cooling, biannual maintenance is often recommended.
Regular maintenance helps:
- improve energy efficiency;
- extend equipment life;
- reduce the risk of breakdowns;
- maintain indoor air quality;
- preserve manufacturer warranty requirements.
During a professional HVAC maintenance visit, technicians typically inspect:
- refrigerant levels;
- electrical connections;
- capacitors and contactors;
- blower components;
- condensate drains;
- filters;
- system performance and safety controls.
Preventive maintenance is generally less expensive than emergency repairs and helps identify problems before they result in system failure.
Do you offer emergency electrical or HVAC services?
Yes. MAIRON HVAC & Electrical Services provides emergency support for urgent electrical and HVAC issues throughout Sacramento and surrounding service areas.
Emergency situations may include:
- complete loss of electrical power;
- burning smells or sparking electrical equipment;
- failed electrical panels;
- HVAC system failures during extreme temperatures;
- damaged service equipment;
- critical commercial system failures.
Our team prioritizes emergency calls and works to restore safety, comfort, and system operation as quickly as possible.
