Get a Free HVAC Inspection and Estimate

We take our inspections seriously. We will stop by your home or commercial space, run detailed diagnostics on your furnace, AC system, ducts, insulation, or your other concern, and take the time to provide a thorough and detailed report. Our inspections usually result in an accurate quote right there on the spot.

We are a small family business, and we keep it that way on purpose. We want to maintain our quality of service, and our customers actually speak with the owner of EM Energy & Air throughout each job. We carefully maintain the quality of our work, and that will never change.

Bay Area Furnace Installation and Repairs

Old furnaces can pose more than just a comfort problem—they can also affect your health and finances. Dust and allergens often circulate through outdated systems, causing respiratory issues and reducing indoor air quality. On top of that, older furnaces consume significantly more energy, which drives up utility bills.

At EM Energy and Air, we offer modern, energy-efficient furnace installations to help you save money while keeping your home cozy during cooler months. Whether you prefer a gas or electric-powered unit, we’ll help you choose a model that fits your home and your budget. Variable-speed units, which adjust airflow for maximum efficiency, are an excellent option for reducing energy consumption without sacrificing comfort.

If your furnace isn’t working as it should, our repair services can diagnose and resolve any issue. From replacing worn-out components to addressing airflow problems, we’ll get your system back in top condition so you can enjoy reliable heating all winter long.

Heat Pump Installation and Repair

Heat pumps are great for the Bay Area because of their  energy-efficiency and ability to both heat and cool your home. They use minimal electricity as well. If your heat pump is underperforming, we offer comprehensive repair services to address common issues like low refrigerant levels, frozen coils, or faulty sensors. For new installations, we’ll recommend models that deliver maximum efficiency and performance. We always prefer high quality American-made models.

Central Air Installation in the Bay Area

If your system isn’t keeping up with the heat, our team can troubleshoot and repair problems like refrigerant leaks, malfunctioning compressors, or clogged drain lines. We also offer new installations for those looking to replace outdated or inefficient units. We can pick the right duct work, install the ducts, and get your HVAC system up to speed

Ductless Mini-Splits

Ductless mini-split systems provide zoned cooling, allowing you to adjust temperatures in individual rooms or spaces. Whether you need a repair or a new installation, our technicians can help you find the right mini-split system for your space.

Ductwork and Duct Cleaning

Your ductwork plays an important role in distributing air throughout your home or business, but over time, it can become clogged with dust, debris, and allergens. Dirty ducts not only reduce the efficiency of your HVAC system but can also hurt your indoor air quality.

We offer professional duct cleaning services to remove buildup and improve airflow. If your ducts are damaged or poorly designed, we can also provide repairs or install new ductwork to optimize your system’s performance. Properly sealed and insulated ducts prevent energy loss, keeping your home comfortable and your utility bills lower.

Insulation Installation and Replacement

Insulation is a key component of any energy-efficient home. Without proper insulation, your heating and cooling system has to work harder to maintain a consistent temperature, leading to higher energy costs and uneven comfort.

We provide expert insulation installation and replacement services to help you achieve maximum efficiency. From upgrading attic insulation to replacing old or damaged materials, we help your home retain heat in the winter and stay cool in the summer. Modern insulation materials are not only more effective but also environmentally friendly. In fact, we only install high quality insulation that is free from formaldehyde.
