Signs You May Need HVAC Repair or Replacement

If your HVAC system is broken or getting near the end of its lifespan, it likely needs repairs or replacement from an HVAC company. Watch for these indicators your system needs service:

  • Thermostat malfunctions or temperature control issues
  • Frequent breakdowns and need for repairs
  • Refrigerant leaks
  • Strange noises when the system turns on
  • Poor air circulation or uneven heating/cooling
  • Cracking, corrosion, or rust
  • Higher than normal energy bills
  • An HVAC system that's over 15 years old

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

Cost of HVAC Installation and Maintenance in San Lorenzo

The cost of HVAC installation or maintenance changes depending on the type of unit you have. Common types of HVAC units include the following:

  • Split or mini-split: If your home lacks the right ductwork for central heating or air, you likely have a split HVAC system. Split or mini-split systems consist of internal units that regulate the temperature in individual rooms, and that are all connected to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system performs similarly to a standard split system, but has the capacity to draw on either electricity or gas for power.
  • Heat pump: Heat pumps transfer hot and cold air between your home and the outdoors. They don't generate their own heating and cooling, so they work best in more temperate climates and may not be as effective during San Lorenzo's hot summers.
  • Packaged heating and air: Packaged HVAC systems work best in smaller homes. They consist of a single combined heating and air conditioning unit, commonly located in a basement or attic. This unit is typically space-saving, energy-efficient, and straightforward to maintain.

The price of HVAC maintenance also varies depending on the kind of work being done. HVAC systems are complex and may require different kinds of maintenance. The cost of some common repairs is as follows:

HVAC Unit TypeCost
Split$2,094-$5,338
Hybrid Split$4,243-$7,817
Heat Pump$3,285-$33,475
Packaged Heating and Air$275-$458

Ways to Save Money on HVAC Costs

It's important to take care of HVAC repairs and replacements in a timely manner, but it can also be expensive. Fortunately, there are steps you can take to slow the wear and tear on your system.

  • Change filters regularly. Switching out or cleaning your air filters every 1–3 months helps air flow smoothly through your HVAC system. You should also try to prevent dirt and debris from building up around the external parts of your system.
  • Keep your system clean. Cleaning your grills, indoor evaporator coil, condenser fan blades, and ductwork regularly helps keep your HVAC system working efficiently and lowers the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it begins to look dirty.
  • Monitor for potential problems. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, helps you resolve them before they get out of hand.
  • Change the position of your blinds seasonally. During winter, leave your blinds open so your home benefits from passive solar heat. In summer, keep blinds shut to block out heat. Doing both decreases the amount of work your HVAC system must perform.
ServiceCost
Filter Replacement$69-$183
Condensor Cleaning$1,375-$4,124
Thermostat Repair$92-$229
Ductwork Cleaning$440-$1,100

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is vital 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

Contact at least three HVAC contractors for quotes. Describe your issues and schedule an in-person inspection if possible. Compare companies' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand upfront payment.

Check Credentials

Look for an HVAC company that employs skilled technicians who have the necessary training and licenses. HVAC contractors in all states must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for all contractors 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 by the state.

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. You should also check reviews and complaints on sites like Google Reviews, the Better Business Bureau (BBB), and Yelp. Pick a company with positive reviews and reports of fantastic customer experiences.

Understand Work Details

Always make sure you know what a company’s process is like. When getting HVAC repairs, ask your provider to specify which parts require replacement and why. Confirm that your technician will clean and test the full system afterward to ensure proper operation. When replacing your HVAC system, ask the contractor to provide details on the new features, model, brand, estimated installation time, and energy efficiency. Before signing a contract, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.

Compare Warranties

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

Get Quote in Writing

Always get HVAC bids in writing before work begins. A thorough quote will cover costs for both materials and labor. Make sure that you agree to all terms before signing the contract.

Frequently Asked Questions About HVAC in San Lorenzo, CA

You should have your HVAC system inspected approximately twice yearly. After the inspection, your technician will tell you if any services are required. You should also schedule an inspection if you notice new issues such as strange noises, leaks, or unusual smells. If your home has ductwork, it should be inspected every few years.

Normally, it's a good idea to schedule inspections in the spring and fall, as these times tend to be less busy. This also helps make sure your system is prepared for the summer and winter, when it typically sees the most use.

You can save energy during the summer by reducing the amount of power your HVAC system uses to keep your home cool. Keep your thermostat temperature as close to the outside temperature as you can, and avoid making drastic changes in temperature all at once. Keep your roof in good shape and seal any leaks around your windows and doors to avoid letting cool air escape. Similarly, ensure that your attic is well ventilated to avoid trapping excess heat in your home.

It takes around one to three days to have an HVAC system installed or replaced. If you need just a furnace or a single air conditioning unit, this might take anywhere from a few hours up to two days. This timeline will be determined by the size of your home, the accessibility of your system, and any new issues your technician uncovers.

For a 2,000-square-foot home, look for a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In San Lorenzo, you may be able to make do with a lower-capacity furnace.

For a 2,000-square-foot home, you'll also want to purchase an air conditioning unit with around 2.5 to 5 tons of capacity. In San Lorenzo, you'll likely need a unit on the higher end of this range. In general, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.

Your HVAC company may offer financing options through a third-party lender, or you may choose to obtain a loan on your own. It's a good idea to discuss payment options with your HVAC company and a financial advisor to make sure that you're choosing the best option for you.

There are several ways you can make your HVAC system more energy-efficient:

  • Make sure your air ducts remain clean, and change or clean your air filters on a regular basis.
  • Have regular inspections to take care of problems as they come up.
  • Keep your attic well-ventilated and make sure all doors and windows are well-sealed.
  • Install a smart thermostat. If you aren't able to purchase one, try keeping the temperature indoors as close to the outside temperature as is comfortable.
  • When replacing part of your HVAC system, explore Energy Star-certified or other environmentally friendly options.
