Our HVAC Services in San Jose

Installation and Replacement of HVAC Systems

At EM Energy and Air, we specialize in installing and replacing a variety of heating and cooling systems. Upgrade your old furnace, install a new air conditioning unit, or explore the benefits of a heat pump or mini-split system. We’ve got you covered.

Furnaces

We can install a range of high-efficiency furnaces that will keep you warm, keep the energy bills reasonable, and last for many years. We’ll assess your home’s specific needs, and recommend the right furnace or system to keep you comfortable. If your current furnace is outdated or requires frequent repairs, it might be time to consider a replacement! We will recommend brands based on your budget and use-case, and we’ll acquire the unit and install it with our trademark warranty.

Mini-Splits

Mini-split systems are perfect for homes that lack ductwork or for adding climate control to specific areas. You can enjoy independent temperature control in different rooms. If you’re looking to cool or heat a specific area of your home, such as a garage, addition, or separate living space, a mini-split system can provide the perfect solution. We would be happy to take a look at your space and help you decide if a mini split system is a good fit.

Air Ducts

You can’t get away with ragged duct work. Leaky or poorly designed ducts can lead to significant energy loss, reduce the effectiveness of your heating and cooling systems, and cause higher bills. We specialize in installing and replacing air ducts to make sure your HVAC system operates at peak performance.

AC Repair in San Jose, CA

When HVAC problems arise, EM Energy and Air is here to help. We can diagnose and repair a wide range of HVAC issues, from minor malfunctions to major breakdowns. Whether your furnace isn’t heating properly, your AC is blowing warm air, or your heat pump is making strange noises, we have the skills and tools to get your system back up and running quickly. We will also be honest regarding a prognosis – if the unit is not worth saving, we will help you pick a new heating or cooling system within your budget.

Other HVAC Services in San Jose

Ductwork

In addition to installing new air ducts, we also offer comprehensive ductwork services, including repairs and maintenance. Ducts can develop leaks, accumulate dust and debris, or become misaligned, all of which can reduce your system’s efficiency and air quality. Rodents may also destroy ducts as they try to access the cool or warm air in your home.

Attic Ventilation

A properly ventilated attic helps regulate your home’s temperature and prevent moisture buildup. Poor ventilation can cause your attic to overheat in the summer and retain moisture in the winter, and this leads to poor energy efficiency and even roof damage. At EM Energy and Air, we assess your attic’s ventilation needs and provide solutions like vents, fans, insulation and more.

Insulation

We offer a variety of insulation services, including installation and replacement of blown-in fiberglass, cellulose, and mineral wool. Whether you need to insulate your attic, walls, or crawlspace, we can recommend and install the right insulation for your home’s specific needs.

And More

We help with attic rodent control, cleaning and disinfecting, home remodeling work, and more. If there’s a service we don’t specifically offer, we can likely make a good recommendation.

Let’s Talk About Efficiency and SEER Rating

What Is a SEER Rating?

If you’re thinking about upgrading your HVAC system, you’ve probably come across the term SEER. It stands for Seasonal Energy Efficiency Ratio. This rating measures the cooling output of an air conditioning unit over a typical season, divided by the total amount of energy it consumes. A higher SEER rating indicates better energy efficiency. For homeowners in San Jose where cooling demand is moderate but consistent, choosing a system with a SEER rating of 15 or higher can reduce your utility bills without sacrificing comfort.

How SEER Impacts Your Utility Bill

Older systems often carry SEER ratings of 10 or lower. Replacing one of those units with a system rated at SEER 16 or 18 can lower your electricity usage during the summer months. Over time, the energy savings can offset the cost of the new installation. Heat pumps also follow similar ratings and often include a separate HSPF (Heating Seasonal Performance Factor) for their heating function. We are happy to explain how those metrics translate into performance and savings for your specific home.

What Affects Overall HVAC Efficiency?

A high SEER rating is only part of the picture. The design and condition of your ductwork, the level of attic insulation, the quality of the installation, and even your thermostat settings all affect how efficiently your system performs. At EM Energy & Air, we take the time to look at every aspect of your home to make sure your HVAC system isn’t working harder than it needs to. If your home has leaky ducts, uneven airflow, or poor zoning, we can help address those issues as part of a new installation or upgrade.

What are signs I may need HVAC repair instead of replacement?

If your system is less than 12–15 years old, and the problem seems limited to a part like the capacitor, thermostat, or blower motor, a repair may be all you need. We’ll always explain your options.

Are your installation warranties really unlimited?

Our labor warranty has no fixed expiration. If we installed it and the problem is due to workmanship, we will fix it. Manufacturer warranties apply separately to parts and equipment.

Do you work on older homes with limited duct access?

Yes. Many of our San Jose clients live in older homes. We offer mini splits and ductless systems for areas where duct installation is difficult or not cost-effective.

How do I know if a heat pump is right for my home?

Heat pumps are ideal for San Jose’s moderate climate. They offer heating and cooling in one unit and are highly efficient. We can evaluate your home’s size, insulation, and usage needs to determine if a heat pump is a good fit.
