Called and spoke with Mrs Garrett's to set up our Gameplan. Was quite knowledgeable and extremely polite. Two qualities lacking in many of her position. Thank you, and we look forward to working with you on our maintenance of our home.

Kevin Faulkner did an amazing job with figuring out our electrical issue and getting it fixed in a timely manner. He was very knowledgeable and helpful. He made my husband and I feel better knowing we are now safe from any major hazards. G4 the company were very good and showed great customer support. They have a great program and deals that we have now taken advantage of that will save us thousands of dollars if anything else should occur. Thanks for not only saving my home but my pockets too!!! I highly recommend G4 and Kevin.

Frequently Asked Questions

How Much Does It Cost To Install Central Air Conditioning?

Central air installation with G4 Electrical is quoted after an in-home evaluation because pricing depends on the system size, efficiency rating, ductwork condition, and any electrical needs.

The biggest factors are matching the unit’s capacity to your home and confirming that the ductwork can deliver air efficiently without leaks or restrictions. We install and replace central air systems across the Austin area, verifying system sizing, refrigerant charge, and duct connections so your new AC performs as designed.

Final pricing is confirmed after on-site testing of your existing system. If your ductwork is in good condition and the electrical system is ready, a straightforward replacement typically costs less than a full retrofit.

Your estimate usually reflects:

  • Equipment capacity (tons) and efficiency rating (SEER2)
  • Duct sealing, modifications, or new duct runs
  • Electrical upgrades or panel work
  • Thermostat, smart controls, and air quality add-ons
  • Old-unit removal and site access

Book an in-home assessment to confirm the exact scope, parts, and timeline before you decide.

Water leak detection in a home is the process of tracing moisture to its exact source and confirming the fix with a controlled re-test. Most problems begin at fixtures or supply connections where cartridges, washers, or flex lines wear out. A licensed plumber starts with a source inspection at the spout, handle, base, or supply lines, explains the findings in plain language, and provides upfront, flat-rate options before work begins.

After approval, the repair is made and re-tested under normal flow to verify the leak is resolved. If symptoms point to hidden or underground piping, sewer-line inspection and trenchless solutions can help reduce disruption. We apply this same step-by-step approach in homes throughout the service area.

What a technician may check next:

  • Fixtures and shut-off valves: Faucets, shower valves, hose bibbs, and nearby stops

  • Supply components: Corroded flex lines, failing stops, or loose connections

  • Drain and sewer lines: Inspection, cleaning, or hydro-jetting when leaks are related to backups

If water is actively leaking, shut off the nearest valve or the main water supply and avoid using the affected fixture until a plumber investigates.

Whole-house water filter installation pricing is finalized after an on-site water test and system sizing because costs vary by filter type, flow capacity, and how your plumbing is configured.

Most price differences come from the media and stages selected, whether a prefilter or bypass is added, and how the unit connects to your main water line. We start with a quick water quality evaluation before recommending equipment that fits your home’s needs.

If your shutoff valves are in good condition and the main water line is accessible, installation is typically more straightforward. Corroded valves, difficult access, or tight installation spaces can add labor and affect the final cost.

Schedule a water test and written quote so you’ll know the exact installed price before any work begins.

“Carlyle found the source of a leak in our water filter; we were convinced it was the service line to the house. He saved us over $1000, time, and digging up the yard for no reason. Great work of doing his diligence on providing the right service.” — David S.

The cost of an electrical inspection for a house varies depending on the home and the scope of the inspection. Standalone inspection pricing depends on factors such as home size, age, and electrical panel complexity, with final pricing confirmed after an on-site review.

Our licensed electricians inspect the electrical systems in your home using National Electrical Code guidance. Most of the inspection focuses on verifying the main electrical panel’s operation, labeling, and grounding, since hidden electrical risks can often be identified there first.

If the electrical panel runs hot, smells burnt, or trips frequently, treat the issue as urgent. Otherwise, a regular electrical safety inspection can help identify potential problems before they become costly or dangerous.

Schedule an inspection when:

  • Buying a property or building new

  • Adding or replacing a major appliance

  • Remodeling

  • The structure is 40+ years old

Ask for an upfront, itemized quote after a brief on-site walkthrough.

“Jason and Tony did great inspection of the whole electrical system of my house.” — Bruce Miglin

Drain cleaning for a clogged drain at G4 Electrical is quoted with upfront, flat-rate pricing after diagnosis, and the cost depends on the clog’s location and severity. Many blockages are simple fixture clogs, while mainline issues or root intrusion require more time and specialized equipment.

Our technicians diagnose drain problems carefully to identify the cause before recommending a solution. You’ll receive clear findings and pricing before work begins, so you know what to expect before the repair is performed.

What drives the final price:

  • Access point and line type: Sink, tub, toilet, or main sewer cleanout

  • Clog makeup and depth: Grease, wipes, heavy buildup, or roots

  • Required methods: Professional auger, camera inspection, hydro-jetting, or trenchless repair

  • Scheduling factors: After-hours or emergency service may affect labor and dispatch costs

For accurate pricing, the final cost is confirmed after an on-site assessment so the recommended solution addresses the actual cause of the blockage.
