Los Angeles Air Conditioning Service

We are experts in the various types of air conditioning units in use in the Los Angeles, CA area.

Mini-Split Systems – These are separate room units often used when ductwork is unavailable.

Central Air Systems – Generally “whole house” air conditioning supplied from one larger unit.

Heat Pumps – Consists of an indoor unit called an air handler and an outdoor unit similar to a central air conditioner.

Package/Roof Mount Units – Generally used on flat roofs using open ductwork.

Window Mount AC Units – These small units are designed to cool a single room, window mounted for ventilation and plugged into a home’s power outlet.

Air Conditioning Installation Services

We offer two of the top brands in heating and cooling, Lennox and Trane. We take into consideration your home’s construction materials, size, room configurations, insulation quality, circuit breakers/panels and ductwork to determine the air conditioning installation system that is right for you.

Air Conditioning Repair & Maintenance Services

Our trucks are well-stocked with heating and air conditioning parts that are most commonly prone to failure in AC units. Most AC repairs can be accomplished in a single trip! In an emergency, our technicians are available after hours and weekends.

Insulation Services in Los Angeles, CA

Not only are we HVAC installers, Nexgen offers a range of experthome insulation services in Los Angeles designed to keep your home more comfortable while saving energy and money.

  • Attic Insulation – Attic insulation is like a blanket for your home, keeping heated air warm in the winter and cooler air inside in the summer.
  • Crawl Space Insulation – The Nexgen team are experts when it comes to finding insulation voids in your home like often-overlooked crawl spaces.
  • Air Duct Insulation – Air ducts are often just thin aluminum pipes that move treated air from your system into the rooms. Ductwork that is not insulated can lose much of its warmth or coolness along the way. Ductwork insulation can make a dramatic difference in the comfort of your home.
  • Exterior Wall Insulation – Outer wall insulation may be minimal or ineffective, especially if you have an older home. Blown-in insulation in outside walls can refresh their insulating power.

Hot Water Heater Tanks in Los Angeles

While proper maintenance can extend the life of your hot water heater, it will need a repair or replacement at some point. Nexgen can help.

  • Water Heaters Installation – Nexgen offers the installation of both traditional and tankless water heaters. Contact us to discuss what is best for you and your family.
  • Water Heater Repairs & Water Heater Maintenance – Water heaters, for the most part, go about their business quietly. They should have annual maintenance like draining. When a water heater stops working, it may still be able to be repaired. Contact the pros at Nexgen before deciding on a replacement water heater.

Air Quality Services for Los Angeles Homeowners

Indoor air quality is a concern in Los Angeles, especially if your family suffers from allergies. We can help with a variety of services designed to improve the quality of your home’s air.

  • Air Quality Assessments – Our indoor air quality testing will help determine the extent of any air quality problems in your home.
  • Air Cleaner Installation – The solution may be a whole house air cleaner. Our HVAC contractors will be happy to discuss your options.
  • Air Duct Cleaning and Sealing – Many indoor air quality problems are caused by clogged air filters and dirty air ducts. New filters and an air duct cleaning and sealing can often resolve these issues.
