Signs You May Need HVAC Repair or Replacement

An HVAC system that's broken or old likely needs professional attention for maintenance or replacement. Watch for these indicators that your system needs service:

• Frequent breakdowns and need for repairs
• Rust, corrosion, or cracking
• Uneven heating/cooling or poor air circulation
• Strange noises when turning on
• Higher than normal energy bills
• Refrigerant leaks
• Thermostat malfunctions or temperature control issues
• An HVAC system that's over 15 years old

Book an inspection if you notice any of these issues. A local technician can assess your system, identify problems, and decide whether you need to fix or replace your HVAC.

Cost of HVAC Installation and Maintenance in San Mateo

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

• Split or mini-split: If your home lacks 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 is able to utilize either gas or electricity for power.
• Heat pump: Heat pumps exchange warm and cool air between your home and outside. These systems don't generate their own heat or AC, so they work more efficiently in moderate climates.
• Packaged heating and air: Packaged HVAC systems work best in smaller homes. They consist of a single combined air conditioner and heating unit, typically located in a basement or attic. This unit is typically space-saving, cost-effective, and straightforward to maintain.

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

Ways to Save Money on HVAC Costs

It’s important to make any essential HVAC fixes or replacements as needed, though they can be expensive. The good news is that homeowners have ways to reduce gradual wear and tear and reduce the frequency of breakdowns.

• Change filters regularly. Air flows best through your HVAC system when you change out or clean the filters every 30–90 days. Also try not to let debris pile up on the external sections of your HVAC.
• Monitor for potential problems. Keeping an eye out for problems, for instance by routinely checking your thermostat and energy bills, helps you resolve them before they get too expensive.
• Keep your system clean. Keeping your grills, condenser fan blades, indoor evaporator coil, and ductwork clean helps your system function optimally and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system whenever it begins to look dirty.
• Change the position of your blinds seasonally. Leaving your blinds open during the winter allows passive solar heating to warm your home. Closing the blinds during the summer helps prevent the same heat from getting inside. Doing both helps reduce the demand on your HVAC system.

How To Choose a Local HVAC Company

It's important to know what makes a good HVAC company. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can keep your system running efficiently, providing you with effective air conditioning and heating for your home.

Compare Multiple Bids

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

Check Credentials

Look for an HVAC company that employs qualified technicians who have the necessary licensure and training. In all states, HVAC contractors must 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." Contractors 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). HVAC contractors are considered specialty contractors by the CSLB. 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 company's reviews and complaints with organizations such as Google Reviews, the Better Business Bureau (BBB), and Yelp. Look for a a company with glowing reviews and stories of positive service experiences.

Understand Work Details

It’s important to understand what the work process is going to look like. For HVAC repairs, the company should list the specific parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to guarantee everything is working correctly. When replacing your HVAC, ask the provider to explain the new model, brand, energy efficiency, estimated installation time, and features. Before work starts, make sure you understand how your provider will determine the right system size for your home and what the price will be.

Compare Warranties

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

Get Quote in Writing

Get written quotes before beginning HVAC work. The quote should cover costs for both labor and materials. Review all terms carefully before signing.
