10 Best HVAC Companies in San Jose, CA

Signs You May Need HVAC Repair or Replacement

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

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

If you notice any of these HVAC issues, you should have a technician inspect your system. A local professional can identify problems and determine whether repairing or getting a new HVAC unit is the correct solution.

Cost of HVAC Installation and Maintenance in San Jose

What you pay for HVAC installation or maintenance is determined by your system style. Common HVAC unit styles include the following:

• Split or mini-split: If your home's ductwork isn’t suited for a central HVAC system, you probably have a split or mini-split system. Split systems have internal units in each room to control temperature; these indoor units all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC unit operates similarly to a regular split system. It gives flexibility by providing the option to draw on either electricity or gas for energy.
• Heat pump: Heat pumps transfer hot and cool air between your home and the outdoors. They don't produce their own heat or AC, so they perform best in temperate climates and may not be as effective during San Jose's hot summers.
• Packaged heating and air: Packaged HVAC systems are a good choice for smaller homes. They have a single cooling and heating unit, typically in an attic or basement. This unit is often compact, energy-efficient, and easy to maintain.

HVAC expenses vary based on the services needed. HVAC systems are complicated and may need a number of types of maintenance. Costs for common jobs are as follows:

Ways to Save Money on HVAC Costs

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

• Keep your system clean. Cleaning your grills, indoor evaporator coil, condenser fan blades, and ductwork 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 when it begins to look dirty.
• 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 HVAC system.
• Monitor for potential problems. Monitoring your system for issues — for example, by checking your thermostat and energy bills routinely — helps you get ahead of problems before they get too expensive.
• Change filters regularly. Air flows best through your HVAC system when you change out or clean the filters every 1–3 months. Also try not to let debris pile up on the outside areas of your HVAC.

How To Choose a Local HVAC Company

Finding the right HVAC company is key 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

Request estimates from at least three HVAC companies. Describe your issues and ask if technicians can inspect your system in person. Compare each company's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid companies that pressure you or demand payment before work.

Check Credentials

Look for an HVAC company that employs skilled technicians with 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 required for any individual who helps "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 at the state level.

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 must have four years of experience and be bonded, and contractors with employees must also meet insurance requirements. Also look at a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Pick a company with positive feedback and stories of satisfied customers.

Understand Work Details

Make sure you know the details of any project before starting. For HVAC repairs, have your provider specify which parts require replacement and why. Confirm that your technician will clean and test the system after the repair to verify that everything works. For replacement, ask your contractor to explain the new HVAC system brand, estimated installation time, energy efficiency, model, and features. Before starting the project, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.

Compare Warranties

A trustworthy HVAC company will stand behind its repair services and equipment installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully compare the fine print between contractors and choose the company that provides the best protection within your budget.

Get Quote in Writing

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