10 Best HVAC Companies in Foster City, CA

Signs You May Need HVAC Repair or Replacement

If your home's HVAC system isn't working correctly or nearing the end of its lifespan, you might need an HVAC contractor for repairs or replacement. Watch for these common signs that your system needs professional attention:

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

If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can diagnose problems and determine whether repair or full HVAC replacement is the best course of action.

Cost of HVAC Installation and Maintenance in Foster City

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

• Split or mini-split: Homes without ductwork for central heating and cooling often have split or mini-split HVAC systems. These systems consist of internal units in each room to regulate temperature. These indoor units connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions much like a standard split system, but has the capacity to draw on either gas or electricity for power.
• Heat pump: Heat pumps exchange warm and cool air between your home and outside. They don't make their own heating and cooling, so they work best in more temperate climates.
• Packaged heating and air: Packaged HVAC systems are a smart choice for smaller houses. These systems have a single heating and cooling unit, typically located in a basement or attic. They're compact, cost-effective, and easy to maintain.

HVAC maintenance costs differ based on the specific services needed. HVAC systems can be complicated and potentially require a number of services. Fees for typical jobs are as follows:

Ways to Save Money on HVAC Costs

It’s important to take care of HVAC repairs and replacements when they are required, though they can be expensive. The good news is that homeowners have ways to minimize progressive deterioration and reduce the frequency of breakdowns.

• Change filters regularly. Air flows best through your HVAC system when you replace or clean the filters every 30–90 days. Also avoid letting debris pile up on the outside areas of your HVAC.
• Keep your system clean. Regularly cleaning ductwork, condenser fan blades, grills, and indoor evaporator coil helps your HVAC system run efficiently and lowers the risk of mold. The National Air Duct Cleaners Association recommends cleaning your heating and cooling system when it starts to look dirty.
• Change the position of your blinds seasonally. Closing your blinds in the summer blocks some passive solar heat from getting indoors. Opening the blinds in the winter allows this same heat to help warm your home. Both of these measures help lower the work required from your HVAC system.
• Monitor for potential problems. Keeping a close eye on the efficiency of your HVAC system — for instance by checking your thermostat settings and energy bills — helps you find and solve issues before they get out of hand.

How To Choose a Local HVAC Company

Knowing the right things to look for in an HVAC company is key for a smooth installation or repair. Established providers with certified technicians can offer assurance your HVAC system will deliver consistent heating and cooling year-round.

Compare Multiple Bids

Contact at least three HVAC companies for quotes. Describe your issues and schedule an in-person inspection if possible. Compare providers' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand upfront payment.

Check Credentials

Look for an HVAC company that employs skilled technicians with the necessary licensure and training. HVAC contractors in all states must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for any individual who helps "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 at the state level.

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

Understand Work Details

Always make sure you know the details of any project. For HVAC repairs, your provider should specify which parts need replacement and why. Confirm that your technician will clean and test your system after repairs are done to ensure that it’s working properly. When replacing your HVAC, have the provider describe the new model, energy efficiency, features, brand, and estimated installation time. Before signing a contract, ask how your provider plans to accurately size the unit for your home and how much it will cost.

Compare Warranties

Reputable HVAC companies back their work with warranties. Compare warranties from different companies, keeping in mind that broader coverage is better. Look for the company that provides the most coverage for a fair price.

Get Quote in Writing

Always get quotes for HVAC service in writing before work begins. A comprehensive quote should cover both labor and materials. Make sure you review all terms before signing a contract.
