HVAC Services in Sunnyvale, CA

When you need an AC or furnace repair in Sunnyvale, we should be the first company you call. Our team can address any problem, from the smallest issue to a major malfunction. Most HVAC issues start small; the symptoms can be immediately noticeable or somewhat subtle at first, but the underlying cause can escalate quickly into a costly repair. Or, if your AC or heater is failing, prompt service can ensure it’s replaced quickly with the right one for your home.

Contact Calvey Heating and Air for HVAC repair or replacement if you notice the following signs of trouble:

• AC blows warm air
• Furnace blows cool air
• Weak airflow
• Loud noises
• Foul odors
• High humidity
• HVAC leak
• Short cycling
• High energy bills

We’re a full-service air conditioning and heating installation company. It’s time to consider replacing your HVAC system if it shows the signs above, is more than 10 years old, or still requires R-22 refrigerant. Also, consider replacing it if frequent repairs have been needed in the past year.

Our technicians also provide annual maintenance. Scheduling tune-ups can ensure your heating and cooling system runs smoothly and efficiently. It can also avoid major repairs by addressing issues early, and extend the lifespan of equipment, protecting your investment. And, aside from correcting potential safety hazards, maintenance is required by many manufacturers to keep your warranty valid.

A broken heater can leave you shivering in winter and is a safety hazard. Gas furnaces can leak carbon monoxide if a combustion problem occurs or the heat exchanger cracks. Even an electric furnace can be a fire hazard. Therefore, it’s important to call an experienced contractor for help when your heating system isn’t working properly. 

At Calvey Heating and Air, our team works quickly to restore your comfort and safety. A lack of heating, weak or yellow pilot light, or noise from a furnace indicates a problem that must be addressed promptly. Our technicians get to the root of the problem and find a permanent solution. As with all of our service calls, a 30-day warranty is included that covers any issue that arises after a repair.

We can fix:

• Gas or power supply problems
• Pilot light issues
• Broken blower components
• Damaged heat exchangers
• Faulty gas valves
• Broken draft inducer motors
• Faulty circuit boards

Ductwork can take up a lot of space and be a source of energy loss. Installing it can require a lot of time and effort, while extending ducts to a finished basement or home addition can be a challenge. A ductless mini split gets around these hassles and is a great choice for smaller Sunnyvale homes.

A mini split system cools the air by circulating refrigerant, like a central AC system does. It includes wall-mounted indoor air handlers that each cool a smaller space, yet are more powerful than portable or window-mounted air conditioners (and quieter). A small conduit connects the outside condenser unit and indoor units, each of which can be turned on and off independently for customized temperature control.

The ability to turn off units in unoccupied rooms saves energy. So does the absence of ductwork that can become contaminated and develop leaks. Additionally, many ductless systems have advanced built-in filtration to improve indoor air quality.

A heat pump is an alternative to a furnace that delivers warm or cool air, depending on the season. It’s an effective solution because of the region’s generally mild temperatures. The benefits include lower energy costs compared to traditional heating and cooling systems, a longer lifespan, and improved indoor air quality. Heat pumps also save space as only one system is needed, and increase safety as they don’t rely on combustion.

In addition, you can qualify for a rebate under the TECH Clean California program if you live in a single-family or small multi-family home. Our team handles all the paperwork. They can also help you with the following heat pump services:

• Installation/Replacement: We can replace your existing HVAC system or install a heat pump for a new construction, providing the right system for your needs and budget. Our team installs air-source, ground-source, and other heat pumps.
• Repair: At Calvey Heating and Air, our technicians fix issues such as a heat pump constantly cycling on and off, making strange noises, or not switching between heating and cooling modes. We provide a fast diagnosis and repair using advanced tools.
• Maintenance: Bi-annual maintenance can avoid costly repairs and early system failures. It includes inspecting major heat pump components, checking electrical parts, tightening connections, sealing duct leaks, lubricating motors, and more. We’ll provide a quote and schedule repairs if needed.

Poor indoor air quality poses a significant risk to human health, and air pollutants tend to be more concentrated inside than they are outdoors. Fortunately, there are various ways to improve the quality of the air you breathe at home. Calvey Heating and Air offers several residential and commercial air quality solutions in Sunnyvale, including the following:

• Air Purifiers: We install High-Efficiency Particulate Air (HEPA) filters with tiny fibers that can remove extremely small particles (down to 0.3µm). These fibers are randomly arranged so the filter can capture them more effectively.
• Humidifiers: Whole-house humidification systems help prevent dry skin, reduce static electricity, and protect wooden furniture. They can also make the air feel warmer without turning up the furnace. 
• Duct Cleaning: The advanced equipment we use loosens debris and vacuums it out of your ductwork, from the vents to the air handler. It enables us to address a major source of indoor air pollution—dirty ducts (we also clean dryer vents).

We are family-owned and committed to customer satisfaction. Prompt, professional service, honesty, and fair pricing help us build lasting relationships. Our technicians also treat your home as if it were their own, ensuring everything is neat and clean while working on your HVAC system. They’re NATE-certified, extensively trained, and highly experienced.

Our team goes to great lengths to get the job done right the first time. We also have you covered with a 30-day warranty on service calls and a 3-year warranty on new equipment installations.
