10 Best HVAC Companies in Redwood City, CA

Signs You May Need HVAC Repair or Replacement

An HVAC system that's malfunctioning or outdated likely needs professional attention for maintenance or replacement. Watch for these signals that your system needs service:

• Cracking, rust, or corrosion
• Odd noises when turning on
• Frequent breakdowns and need for repairs
• Thermostat malfunctions or temperature control issues
• Refrigerant leaks
• Uneven heating/cooling or poor air circulation
• Unusually high energy bills
• 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 identify problems and determine whether repair or full HVAC replacement is the better solution.

Cost of HVAC Installation and Maintenance in Redwood City

Your HVAC installation or maintenance cost varies depending on the type of unit. Common HVAC unit varieties include the following:

• Split or mini-split: Homes without ductwork for centralized climate control frequently have split or mini-split HVAC systems. These systems consist of indoor units in each room to control temperature, which all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions much like a standard split system, but is able to utilize either gas or electricity for power.
• Heat pump: Heat pumps move warm and cool air between your home and outside. These systems don't generate their own heat or AC, so they work better in milder climates.
• Packaged heating and air: Packaged HVAC systems are a good choice for smaller houses. They have a single cooling and heating unit, normally in an attic or basement. This unit is often small, cost-effective, and easy to maintain.

HVAC expenses vary based on the work needed. HVAC systems are complicated and may need multiple types of maintenance. Prices for common jobs are as follows:

Ways to Save Money on HVAC Costs

Fixing your HVAC by repairing or replacing parts when needed is crucial, but can be costly. Luckily, there are actions you can take to minimize wear and tear over time on your system.

• Change the position of your blinds seasonally. Keeping your blinds open in the winter helps you take advantage of passive solar heating. Keeping them closed in the summer helps keep some of this heat out. Both of these measures help reduce the strain on your HVAC system.
• Keep your system clean. Cleaning your ductwork, indoor evaporator coil, condenser fan blades, and grills regularly helps your HVAC system work efficiently and lowers the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.
• Change filters regularly. Cleaning or replacing your air filters every 30–90 days helps air flow smoothly through your system. Also try to keep debris away from the outdoor portions of your HVAC system as much as possible.
• Monitor for potential problems. Monitoring your system for problems — for example, by checking your thermostat and energy bills routinely — helps you catch issues before they get too expensive.

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is crucial for an easy installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.

Compare Multiple Bids

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

Check Credentials

It's important to choose an HVAC company that employs technicians with the proper qualifications and expertise. In all states, HVAC contractors have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, a contractor must pass an exam (the specific exam depends on what kind of equipment they plan to work with). Section 608 certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." 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). 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. You should also check a provider's reviews and complaints with organizations such as the Better Business Bureau (BBB), Google Reviews, and Yelp. You want to hire a company with glowing reviews and stories of positive service experiences.

Understand Work Details

It’s important to understand what the work process will look like. For HVAC repairs, the company should detail the particular parts that need replacement and why. Confirm that your technician will clean and test your system afterward to guarantee everything is working correctly. When replacing your HVAC system, ask the contractor to provide details on the new estimated installation time, features, brand, model, and energy efficiency. Before signing a contract, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.

Compare Warranties

A trustworthy HVAC company will back its repair work and equipment installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully review warranty terms for each contractor and choose the provider that offers the greatest protection at a reasonable price.

Get Quote in Writing

Always get HVAC estimates in writing before work begins. A comprehensive quote will cover costs for both materials and labor. Make sure that you agree to all terms before signing the contract.
