10 Best HVAC Companies in Mountain View, 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 fixes or install a new unit. Watch out for these common indicators that your HVAC needs service:

• Frequent breakdowns and need for repairs
• Odd noises when turning on
• Higher than normal energy bills
• Poor air circulation or uneven heating/cooling
• Cracking, rust, or corrosion
• Refrigerant leaks
• Temperature control issues or thermostat malfunctions
• 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 best course of action.

Cost of HVAC Installation and Maintenance in Mountain View

HVAC installation or maintenance costs change depending on your system. Common HVAC unit varieties include the following:

• Split or mini-split: If your home doesn't have the right ductwork for central heating or air, you likely have a split HVAC system. Split or mini-split systems consist of indoor units that regulate the temperature in individual rooms, and that are all connected to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions very similarly to a standard split system. It has the benefit of being able to utilize either gas or electricity for power.
• Heat pump: Heat pumps transfer warm and cold air between your home and the outdoors. They don't produce their own heat or AC, so they work best in mild climates and may not be as effective during Mountain View's hot summers.
• Packaged heating and air: Packaged HVAC systems work well in smaller houses. They consist of a single combined air conditioner and heating unit, typically located in a basement or attic. This unit is typically compact, cost-effective, and easy to maintain.

The price of HVAC maintenance also varies depending on the kind of work you're having done. HVAC systems are complicated and can require different kinds of maintenance. The cost of some common repairs is as follows:

Ways to Save Money on HVAC Costs

It's important to repair or replace your HVAC system when it's broken, but it can also be expensive. Thankfully, there are some steps you can take to reduce wear and tear 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. Keeping your indoor evaporator coil, grills, condenser fan blades, and ductwork clean helps your system function optimally and reduces the chance of mold growth. The National Air Duct Cleaners Association recommends that you clean your HVAC system when it starts to look dirty.
• Change filters regularly. Air flows through your HVAC system most effectively when you change out or clean the filters every 30–90 days. Also avoid letting debris pile up on the external sections of your HVAC.
• 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 too expensive.

How To Choose a Local HVAC Company

It's important to know what makes a good HVAC company. A properly licensed contractor with the right experience will give you confidence that they can maintain your HVAC system properly, providing you with effective heating and cooling in your home.

Compare Multiple Bids

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

Check Credentials

It's important to choose an HVAC company that employs technicians with the proper qualifications and expertise. HVAC contractors in all states have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, individuals must pass an exam (the type of 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 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. Reviewing feedback on Google Reviews, Yelp, the Better Business Bureau (BBB), and similar sites can assist your decision. Choose a company with great reviews and reports of positive experiences from 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 particular parts that need replacement and why. Confirm that your technician will clean and test your system afterward to guarantee everything is working correctly. For replacement, ask your contractor to explain the new HVAC system estimated installation time, brand, model, features, and energy efficiency. Before signing a contract, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

A reputable HVAC company will stand behind its repair services and 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 best protection at a reasonable price.

Get Quote in Writing

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