Energy-efficient heating solutions for your California home.

Heating your home shouldn’t be a challenge. Sadly, many California residents find themselves spending far too much money on their heating bill, especially through the cooler months of the year. There are a number of home heating solutions that can allow you to move toward enhanced home performance, and Greiner is ready to help determine which is right for your home.

Heating Service and Installation

  • Furnaces — The furnaces of the past are anything but energy efficient. Greiner sells and installs new high-efficiency furnaces that are ideal for those who are looking to stick with a traditional HVAC system, yet want to save money on their monthly heating bill.
  • Mini-split Heat Pumps — Mini-splits are extremely popular today, and for good reason. They’re considered by many in the home performance industry to be the most energy-efficient heating solution available, offering flexibility in installation like no other option can.
  • Indoor Air Quality — The quality of the air you and your family breathes should never be left to chance. At Greiner, we only install heating systems that promote strong indoor air quality (IAQ), ensuring that your home is a safe and healthy environment year-round.
  • Ventilation Systems / Ductwork — Not all ventilation systems are designed to best suit the homes they’re in, and ductwork can easily suffer damage such as cracks and leaks. We’ll help you make any modifications that might be necessary or even install a completely new ventilation system for your home.

High-efficiency furnaces for true home comfort.

California residents owe it to themselves to heat their homes with modern, energy-efficient furnaces. Unfortunately, not everyone has made the switch. Many homeowners heat with old, outdated furnaces that are anything but efficient, often without even realizing the amount of money they’re losing in the process.

Greiner installs high-efficiency furnaces that are perfect for anyone working toward achieving true home performance.

Energy-efficient home heating at its very best.

Mini-split heat pumps are the premier choice for those who want to improve home comfort while also saving money on their energy bill. A relatively new type of home heating system, mini-splits operate without ducts and offer flexibility of placement in practically any room throughout your home. For California homeowners currently using an old furnace, making the jump to mini-split heat pumps is like night and day.

Greiner Heating Indoor Air

Because you deserve to breathe free and clear in your own home.

Have you ever thought about the quality of the air you’re breathing at home? The thing is, most people don’t unless there’s something obviously wrong. No one wants to breathe poor-quality air day-in, day-out, and in many cases, doing so can prove to be more than a simple nuisance. The air inside your home doesn’t have to be poor quality, and understanding what can affect indoor air quality (IAQ) is the first step toward remedying whatever issues may exist.

Your ducts are the “lungs” of your home – don’t overlook their importance.

It’s common to take certain aspects of the home for granted. Take your home’s ductwork and ventilation system, for example. Ductwork allows the warm air generated by your home heating system to move from room to room, yet most people go through their day without even taking note of this. The issue with this is that problems associated with ventilation systems and duct design do happen, and they can have a marked effect on home performance.
