10 Best HVAC Companies in Milpitas, CA

Signs You May Need HVAC Repair or Replacement

An HVAC system that's broken or past its lifespan likely needs professional attention for repairs or replacement. Watch for these signs that your system needs service:

• Frequent breakdowns and need for repairs
• Thermostat malfunctions or temperature control issues
• Strange noises when turning on
• Corrosion, rust, or cracking
• Unusually high energy bills
• Refrigerant leaks
• Poor air circulation or uneven heating/cooling
• An HVAC system that's over 15 years old

If you see any of these HVAC issues, have a technician inspect your system. A local professional can detect problems and let you know whether whether repairing or getting a new HVAC unit is the correct solution.

Cost of HVAC Installation and Maintenance in Milpitas

The cost of HVAC installation or maintenance varies depending on the kind of unit you have. Common varieties of HVAC units include the following:

• Split or mini-split: If your home doesn't have the right ductwork for central air or heating, you probably have a split HVAC system. Split or mini-split systems consist of indoor units that regulate the temperature in individual rooms. These interior units are all connected to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions very similarly to a standard split system. It has the advantage of being able to utilize either electricity or gas for power.
• Heat pump: Heat pumps transfer warm and cool air between your home and outside. These systems don't generate their own heat or AC, so they work more effectively in milder climates and may not be as effective during Milpitas' hot summers.
• Packaged heating and air: Packaged HVAC systems are good for smaller houses. Packaged systems consist of a single heating and cooling unit, typically located in an attic or basement. This unit tends to be compact, efficient, and easy to maintain.

HVAC maintenance prices vary depending on the particular service needed. HVAC systems are complex and might require different kinds of maintenance. Costs for some common services are as follows:

Ways to Save Money on HVAC Costs

Fixing your HVAC by repairing or replacing parts when needed is important, but can be costly. Fortunately, there are actions you can take to reduce gradual wear and tear on your system.

• Monitor for potential problems. Keep an eye on your system for issues, for example by consistently checking your thermostat and energy bills. This helps you address problems before they get too expensive.
• Change filters regularly. Changing your air filters or washing them every 30–90 days allows effective air circulation through your HVAC system. Also try to keep debris from accumulating on the outdoor sections of your HVAC.
• Keep your system clean. Cleaning your ductwork, indoor evaporator coil, grills, and condenser fan blades regularly helps your HVAC system work efficiently and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system once it starts to look dirty.
• Change the position of your blinds seasonally. During winter, leave your blinds open so your home benefits from passive solar heat. In summer, keep blinds shut to block out heat. Doing both decreases the amount of work your HVAC system is required to do.

How To Choose a Local HVAC Company

Knowing the indicators of a good HVAC company is important. A properly licensed contractor with the right experience will give you confidence that they can fix your system, providing you with effective heating and cooling for your home.

Compare Multiple Bids

Request estimates from three or more HVAC companies. Describe your issues and ask if technicians can inspect your system in person. Compare each company's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid companies that pressure you or demand payment before work.

Check Credentials

When hiring an HVAC provider, choose one with technicians that have the right training, licenses, and experience. In all states, HVAC contractors need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for all contractors who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." An individual must pass an exam (the type of exam depends on what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled on a state-by-state basis.

In California, HVAC contractors must be licensed by the Department of Consumer Affairs Contractors State License Board (CSLB). The CSLB considers HVAC contractors to be specialty contractors. All contractors are required to have four years of experience and to be bonded. Contractors with employees must also meet insurance requirements. Always check a provider's reviews and complaints with organizations such as Google Reviews, Yelp, and the Better Business Bureau (BBB). You'll want to select a company with glowing reviews and stories of positive service experiences.

Understand Work Details

Make sure you know the details of any project before it begins. If HVAC repairs are required, have your provider detail which parts require replacement and why. Get confirmation that your technician will clean and test the entire system after the repair to ensure that everything works. When replacing your HVAC system, ask the contractor to provide details on the new energy efficiency, features, brand, estimated installation time, and model. Before work begins, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.

Compare Warranties

Trustworthy HVAC companies provide warranties for their work. Broader coverage is better, so make sure to review warranties between companies. Choose the one that provides the most comprehensive coverage at a fair cost.

Get Quote in Writing

Get a written estimate before HVAC work begins. A full quote includes both labor and material costs. Make sure you understand and accept all terms before signing the contract.
