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:

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

These HVAC red flags indicate that you should have your system evaluated. A local company 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 Vacaville

What you spend on HVAC installation or maintenance depends on your system type. Common HVAC unit styles include the following:

  • Split or mini-split: If your home doesn’t have the ductwork for central air or heating, you likely 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 unit operates similarly to a regular split system. It provides flexibility by providing the option to draw on either electricity or gas for energy.
  • Heat pump: Heat pumps circulate hot and cool air between your home and the outdoors. They don't produce their own heat or AC, so they perform best in mild climates and may not be as effective during Vacaville'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, usually located in a basement or attic. This unit is typically small, energy-efficient, and straightforward to maintain.

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

HVAC Unit Type Cost
Split $2,004-$5,109
Hybrid Split $4,061-$7,482
Heat Pump $3,144-$32,041
Packaged Heating and Air $263-$439

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 reduce gradual wear and tear and reduce the frequency of breakdowns.

  • Change filters regularly. Air flows best through your HVAC system when you change out or clean the filters every 1–3 months. Also avoid letting debris pile up on the outside areas of your HVAC.
  • 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 amount of work your HVAC system needs to do.
  • 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.
  • Keep your system clean. Keeping your ductwork, condenser fan blades, indoor evaporator coil, and grills clean helps your system function optimally and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.

Service Cost
Filter Replacement $66-$175
Condensor Cleaning $1,316-$3,947
Thermostat Repair $88-$219
Ductwork Cleaning $421-$1,053

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

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

Check Credentials

When hiring an HVAC provider, choose one with technicians that have the appropriate training, licenses, and experience. HVAC contractors in all states need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all technicians 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 the type of equipment they intend to work with) to be certified by the EPA. 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). The CSLB considers HVAC contractors to be specialty contractors. All contractors must have four years of experience and be bonded, and contractors with employees must also meet insurance requirements. You should also read reviews and complaints on sites like the Better Business Bureau (BBB), Google Reviews, and Yelp. Choose a company with glowing reviews and reports of great customer experiences.

Understand Work Details

Make sure you understand the details of any project before it begins. When getting HVAC repairs, have your provider specify which parts need replacement and why. Get confirmation that your technician will clean and test your system after the repair to verify that everything works. When replacing your HVAC, have the contractor explain the new energy efficiency, model, brand, features, and estimated installation time. Before work starts, make 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

Good HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Compare warranty details between providers and pick the one that offers the best protection for the fairest price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Vacaville, CA

Typically, you should have your HVAC system inspected twice a year. After that inspection, your HVAC technician will tell you what services are required. You should also have an inspection if you start to notice any issues, such as unusual smells, strange noises, or leaks. If your home has ductwork, it should be serviced every few years.

The best times of the year to have an HVAC inspection are during the spring and fall. Technicians are less busy during these times, so it will be easier to get an appointment. This also ensures that your system is ready for the summer and winter, which is when it normally gets 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 you can, and avoid making drastic changes in temperature all at once. Keep your roof in good shape and seal any door or window leaks to avoid letting cool air escape. Similarly, make sure your attic is well ventilated to avoid trapping excess heat in your home.

It takes between one and three days to have your HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this might take anywhere from a few hours up to two days. This timeline can be affected by the size of your house, the accessibility of your system, and any new issues your technician runs into.

For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. In Vacaville, you'll probably want to purchase a unit on the higher end of this range. For a house over 1,000 square feet, central air will usually be more effective than window units for cooling.

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

Usually, HVAC financing is provided by a third-party lender. If your HVAC company doesn't offer these options, you could consider taking out a loan on your own. Be sure to talk to a financial advisor and your HVAC company to find out what options are available to you and appropriate for your situation.

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 regularly.
  • Have regular inspections to take care of issues as they come up.
  • 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 it comes time to replace any part of your system, explore Energy Star-certified or other environmentally friendly options.
