10 Best HVAC

Signs You May Need HVAC Repair or Replacement

An HVAC system that's not working properly or old likely needs professional attention for repairs or replacement. Watch for these signals that your system needs service:

• Temperature control issues or thermostat malfunctions
• Refrigerant leaks
• Odd noises when the system turns on
• Higher than normal energy bills
• Frequent breakdowns and need for repairs
• Poor air circulation or uneven heating/cooling
• Cracking, rust, or corrosion
• 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 pinpoint problems and determine whether repair or full HVAC replacement is the better solution.

Cost of HVAC Installation and Maintenance in Los Altos

What you spend on HVAC installation or maintenance depends on your system style. Common HVAC unit styles include the following:

• Split or mini-split: If your home doesn't have the right ductwork for central air or heating, you likely have a split HVAC system. Split or mini-split systems consist of interior units that control the temperature in individual rooms. These interior units are all connected 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 work by circulating hot and cold air between your home and the outdoors. These systems don't create heat or air conditioning themselves, and are better for more moderate climates. They may not be as effective during Los Altos' hot summers.
• Packaged heating and air: Packaged HVAC systems are good for smaller homes. These systems consist of a single combined heating and cooling unit, typically located in a basement or attic. This unit tends to be compact, efficient, and easy to maintain.

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

Ways to Save Money on HVAC Costs

HVAC upkeep is important, but can be pricey. Luckily, homeowners can take steps to reduce wear and tear on their system and lower future maintenance needs.

• Change the position of your blinds seasonally. Keeping your blinds closed in the summer helps block out passive solar heat. Keeping them open in the winter helps you take advantage of this same heat. Both of these measures help reduce the frequency with which you need to run your HVAC.
• Change filters regularly. Switching out or cleaning your air filters every 30–90 days helps air flow efficiently through your HVAC system. We also recommend regularly clearing dirt and debris away from the external parts of your system.
• Monitor for potential problems. Monitor your system for issues, for example by routinely checking your thermostat and energy bills. This allows you to address issues before they get too expensive.
• Keep your system clean. Cleaning your grills, ductwork, condenser fan blades, and indoor evaporator coil regularly helps keep your HVAC system working 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.

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is important for a successful project. Look for an experienced, licensed contractor that can give you peace of mind and make sure your system provides reliable heating and air conditioning for your home.

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Describe the issues and have specialists visit to inspect your HVAC system if possible. Compare the companies' explanations, solutions, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand payment upfront.

Check Credentials

When picking an HVAC provider, choose one with technicians that have the appropriate training, licenses, and experience. HVAC contractors in all states need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for all technicians 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 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, and contractors with employees must also meet insurance requirements. Also look at a company's reviews and complaints on sites such as Google Reviews, the Better Business Bureau (BBB), and Yelp. Pick a company with great feedback and stories of satisfied customers.

Understand Work Details

It’s important to understand what the work process is going to look like. For HVAC repairs, the company should explain the exact parts that need replacement and why. Confirm that your technician will clean and test the full system afterward to guarantee everything is working correctly. When getting a replacement, ask the contractor to explain the new HVAC system brand, model, energy efficiency, estimated installation time, and features. 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 providers and pick the one that offers the most comprehensive protection within your budget.

Get Quote in Writing

Always get quotes for HVAC service in writing before committing to a provider. An itemized quote should cover both materials and labor. Make sure you understand all terms before signing a contract.
