10 Best HVAC Companies in Los Altos Hills, CA

Signs You May Need HVAC Repair or Replacement

A malfunctioning or aging HVAC system probably needs professional attention from a technician who can make repairs or install a new unit. Watch out for these common signs that your HVAC needs service:

• Frequent breakdowns and need for repairs
• Temperature control issues or thermostat malfunctions
• Uneven heating/cooling or poor air circulation
• Refrigerant leaks
• Unusually high energy bills
• Corrosion, rust, or cracking
• Strange noises when the system turns on
• An HVAC system that's over 15 years old

If you're experiencing any of these HVAC issues, have a technician inspect your system. A local professional can detect problems and decide whether fixing or replacing your HVAC unit is the correct solution.

Cost of HVAC Installation and Maintenance in Los Altos Hills

The price of HVAC installation or maintenance varies depending on the type of unit you have. Common kinds of HVAC units include the following:

• Split or mini-split: Homes without ductwork for centralized climate control often have split or mini-split HVAC systems. These systems consist of internal units in each room to control temperature, which all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system operates similar to a normal split system, but has the advantage of being able to utilize energy from either electric or gas sources.
• Heat pump: Heat pumps transfer warm and cool air between your home and outside. They don't create their own heating and cooling, so they work more efficiently in more temperate climates and may not be as effective during Los Altos Hills' hot summers.
• Packaged heating and air: Packaged HVAC systems are often a good option for smaller homes. They consist of a single combined heating and cooling unit, typically located in an attic or basement. This unit tends to be compact, efficient, and easy to maintain.

The amount you spend on HVAC maintenance also varies depending on what kind of work you're having done. HVAC systems are complicated and can require different kinds of maintenance. The prices of some common jobs are as follows:

Ways to Save Money on HVAC Costs

HVAC system repairs and replacements are important, but can be pricey. Thankfully, homeowners can take steps to reduce wear and tear on their HVAC and lower future maintenance needs.

• Keep your system clean. Cleaning your ductwork, grills, condenser fan blades, and indoor evaporator coil 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 when it starts to look dirty.
• Change filters regularly. Replacing or cleaning your air filters every 1–3 months helps air flow smoothly through your system. Also try to keep debris away from the external sections of your HVAC system as much as possible.
• Monitor for potential problems. Monitoring the efficiency of your HVAC system — for instance by reviewing your thermostat settings and energy bills — helps you identify and fix problems before they get out of hand.
• Change the position of your blinds seasonally. Opening your blinds in winter allows passive solar heat into your house. Closing your blinds in summer blocks some heat from getting indoors. Both of these measures help lower the work required from your home’s HVAC system.

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

Get quotes from three or more HVAC companies. Explain your issues and ask if specialists can inspect your system in person. Review each provider's diagnoses, recommended solutions, estimated cost, warranties, and timeline. Avoid companies that pressure you or demand payment before work.

Check Credentials

Choose an HVAC company with skilled technicians who have proper licensing and experience. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, contractors must pass an exam (the specific exam depends on the kind of equipment they intend 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.

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 company's reviews and complaints with organizations such as Yelp, the Better Business Bureau (BBB), and Google Reviews. Choose a provider with glowing reviews and stories of positive service experiences.

Understand Work Details

Make sure you know the details of your project before it begins. For HVAC repairs, have your provider specify which parts require replacement and why. Get confirmation that your technician will clean and test your system after the repair to ensure that everything works. When getting a replacement, ask the contractor to explain the new HVAC system features, brand, model, estimated installation time, and energy efficiency. Before starting the project, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

Reliable HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Review warranty details between companies and pick the one that offers the best protection within your budget.

Get Quote in Writing

Get a written quote before HVAC work starts. A comprehensive quote includes both labor and material costs. Make sure you understand and agree to all terms before signing the contract.
