Signs You May Need HVAC Repair or Replacement

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

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

If you see any of these HVAC issues, we recommend having a technician inspect your system. A local professional can identify problems and decide whether fixing or replacing your HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Walnut

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

  • Split or mini-split: If your home lacks the ductwork for central heating and cooling, you likely have a split or mini-split system instead. Split HVAC systems have interior units in each room to control temperature. These connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions comparably to a regular split system. It gives flexibility by providing the option to use either electricity or gas for energy.
  • Heat pump: Heat pumps work by circulating hot and cold air between your home and the outdoors. These systems don't produce heat or air conditioning themselves, and are better for more moderate climates. They may not be as effective during Walnut's hot summers.
  • Packaged heating and air: Packaged HVAC systems work well in smaller houses. They consist of a single combined heating and air conditioning unit, typically located in an attic or basement. This unit is typically space-saving, energy-efficient, and easy to maintain.

HVAC maintenance prices vary based on the specific services needed. HVAC systems can be complex and potentially require several different services. Costs for typical jobs are as follows:

HVAC Unit Type Cost
Split $1,918-$4,889
Hybrid Split $3,886-$7,159
Heat Pump $3,009-$30,658
Packaged Heating and Air $252-$420

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 minimize progressive deterioration and reduce the frequency of breakdowns.

  • Monitor for potential problems. Monitoring the efficiency of your HVAC system — for instance by reviewing your thermostat settings and energy bills — helps you find and solve issues before they get out of hand.
  • Keep your system clean. Regularly cleaning ductwork, grills, indoor evaporator coil, and condenser fan blades helps your HVAC system run efficiently and lowers the risk of mold. The National Air Duct Cleaners Association advises cleaning your heating and cooling system when it starts 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 in warmer seasons helps prevent some heat from getting inside. Doing both helps reduce the demand on your HVAC system.
  • Change filters regularly. Switching out your air filters or washing them every 1–3 months allows effective air circulation through your HVAC system. You should also try to keep debris from accumulating on the outdoor sections of your HVAC.

Service Cost
Filter Replacement $63-$168
Condensor Cleaning $1,259-$3,777
Thermostat Repair $84-$210
Ductwork Cleaning $403-$1,007

How To Choose a Local HVAC Company

Knowing the indicators of a good HVAC company is important. 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 heating and cooling in 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 contractors' explanations, solutions, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand payment upfront.

Check Credentials

Choose an HVAC company with well-trained technicians who have appropriate licensing and experience. In all states, HVAC contractors have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, a contractor must pass an exam (the type of exam depends on what kind of equipment they plan 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 at the state level.

HVAC contractors in California 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. Checking reviews on the Better Business Bureau (BBB), Google Reviews, Yelp, and similar sites can help your decision. Choose a provider with stellar reviews and stories of positive experiences from customers.

Understand Work Details

It’s important to know what the work process will look like. For HVAC repairs, the company should explain the particular parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to ensure proper functioning. When replacing your HVAC, ask the contractor to provide details on the new brand, features, energy efficiency, model, and estimated installation time. Before work begins, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.

Compare Warranties

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

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Walnut, CA

Normally, you should have your HVAC system inspected twice a year. After an inspection, your HVAC technician will tell you what, if any, services are required. You should also call a technician if you notice any new issues, like unusual smells, strange noises, or leaks. If you have ductwork in your home, it should be serviced every few years.

The best times to have an HVAC inspection are during the spring and fall. Technicians tend to be less busy during these times, making it easier to get an appointment. This also helps get your system ready for the summer and winter, the times of the year when it sees the most use.

You can save energy during the summer by making it easier for your HVAC system to keep your home cool. Set your thermostat as close to the outside temperature as is comfortable, and try to avoid making drastic changes in temperature all at once. Keep your roof in good shape and seal any door or window leaks to help keep cool air in. Similarly, make sure your attic is well ventilated to avoid trapping excess heat in your home.

It takes roughly 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 may take anywhere from a few hours up to two days. This timeline can be influenced by the size of your house, the accessibility of your system, and any new issues your technician uncovers.

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

For a 2,000-square-foot home, you'll also want to look for an air conditioning unit with around 2.5 to 5 tons of capacity. In Walnut, you'll likely look for a unit on the higher end of this range. Usually, 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 might be able to obtain a loan on your own. It's smart to discuss payment options with your HVAC company and a financial advisor to make sure that you find the best option for you.

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

  • Keep ductwork clean, and clean or change your air filters on a regular basis.
  • Schedule regular inspections to take care of issues 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 it comes time to replace any part of your HVAC system, explore Energy Star-certified or similar environmentally friendly options.
