Signs You May Need HVAC Repair or Replacement

If your HVAC system is faulty or getting old, it likely needs servicing or replacement from an HVAC company. Look for these indicators your system needs service:

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

These HVAC red flags indicate that you should have your system evaluated. A local technician can complete an inspection, diagnose problems, and advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in Simi Valley

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

  • Split or mini-split: If your home lacks the ductwork for central air or heating, you probably have a split or mini-split system instead. Split HVAC systems have interior units in each room to manage 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 having 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 more suited to more moderate climates. They may not be as effective during Simi Valley's hot summers.
  • Packaged heating and air: Packaged HVAC systems work best 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, energy-efficient, and easy to maintain.

The cost of HVAC maintenance also varies depending on what kind of work being done. HVAC systems are complicated and might require different kinds of maintenance. The prices of some common jobs are as follows:

HVAC Unit TypeCost
Split$1,932-$4,925
Hybrid Split$3,915-$7,213
Heat Pump$3,031-$30,888
Packaged Heating and Air$254-$423

Ways to Save Money on HVAC Costs

Essential HVAC maintenance is important, but can be expensive. Fortunately, homeowners can take steps to reduce wear and tear on their system and lower future maintenance needs.

  • Change the position of your blinds seasonally. Leaving your blinds open during the colder months 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 strain on your HVAC system.
  • Keep your system clean. Cleaning your grills, indoor evaporator coil, ductwork, and condenser fan blades 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.
  • Change filters regularly. Switching out your air filters or washing them every 1–3 months allows effective air circulation through your system. Also try to keep debris from accumulating on the external parts of your HVAC.
  • Monitor for potential problems. Monitoring the efficiency of your HVAC system — for instance by checking your thermostat settings and energy bills — helps you identify and fix problems before they get too expensive.
ServiceCost
Filter Replacement$63-$169
Condensor Cleaning$1,268-$3,805
Thermostat Repair$85-$211
Ductwork Cleaning$406-$1,015

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is important for a successful project. Look for an experienced, licensed contractor that can offer you peace of mind and ensure your system provides reliable air conditioning and heating for your home.

Compare Multiple Bids

Request estimates from three or more HVAC companies. Explain your issues and ask if technicians can inspect your system in person. Review each provider's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid companies that pressure you or demand payment before work.

Check Credentials

It's important to choose an HVAC company that employs technicians with the appropriate qualifications and expertise. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, contractors must pass an exam (the specific 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 by the state.

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. Contractors with employees must also meet insurance requirements. Reviewing feedback on Google Reviews, the Better Business Bureau (BBB), Yelp, and similar sites can help your decision. Choose a provider with great reviews and reports of positive customer experiences.

Understand Work Details

Make sure you know the details of your project before starting. If HVAC repairs are required, have your provider detail which parts need replacement and why. Confirm that your technician will clean and test the entire system after the repair to verify that everything works. When replacing your HVAC, have the contractor explain the new energy efficiency, features, brand, model, and estimated installation time. Before signing paperwork, be sure you understand the process your provider will use to size the new HVAC system appropriately for your home and what the price will be.

Compare Warranties

A trustworthy HVAC company will back its repair services and equipment installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully compare warranty terms between contractors and choose the company that provides the best protection at a reasonable price.

Get Quote in Writing

Always get estimates for HVAC service in writing before committing to a provider. A comprehensive quote should cover both labor and materials. Make sure you agree to all terms before signing a contract.

Frequently Asked Questions About HVAC in Simi Valley, CA

You should have your HVAC system inspected about twice yearly. After the inspection, your technician will inform you if any services are required. You should also call a technician if you start noticing issues such as strange noises, leaks, or unusual smells. If your system has ductwork, you should have it inspected every few years.

Normally, it's smart 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 likely 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. Set your thermostat as close to the outside temperature as you comfortably can, and try to avoid making drastic changes in temperature all at once. Keep your roof in good shape and seal any leaks around your doors and windows 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 only need an air conditioning unit or a furnace, this can take between half a day and two days. This timeline can be affected by the size of your house, how easily accessible your system is, and any new issues your technician runs into.

For a 2,000-square-foot home, you should look for a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In Simi Valley, you may be able to make do with a furnace on the lower end of this range.

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

Normally, HVAC financing is through a third-party lender. If your HVAC company doesn't offer financing, you could consider taking out a loan on your own. Be sure to speak with your HVAC company and a financial advisor to learn what options are available to you and appropriate for your situation.

There are a number of ways you can make your HVAC system more energy-efficient:

  • Make sure your air ducts remain clean, and clean or change your air filters regularly.
  • Schedule regular inspections to take care of issues as they arise.
  • Make sure your doors and windows are well-sealed and keep your attic well-ventilated.
  • Install a smart thermostat. If you don't want to or can't buy one, try keeping your inside temperature as close to the outside temperature as is comfortable.
  • When replacing part of your system, explore Energy Star-certified or similar environmentally friendly options.
