Today's Homeowner looks at dozens of datapoints on hvac companies to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
A faulty or aging HVAC system probably needs professional attention from a technician who can make fixes or install a new unit. Look out for these common signs that your HVAC needs service:
Schedule an inspection if you notice any of these issues. A local technician can inspect your system, identify problems, and figure out whether you need repairs or a new HVAC unit.
HVAC installation or maintenance prices change depending on your system. Common HVAC unit varieties include the following:
HVAC maintenance prices vary depending on the particular service needed. HVAC systems are complicated and can require different kinds of maintenance. Fees for some common services are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $2,024-$5,159 | |
| Hybrid Split | $4,100-$7,554 | |
| Heat Pump | $3,175-$32,351 | |
| Packaged Heating and Air | $266-$443 |
It's important to repair or replace your HVAC system when it's broken, but it can also be expensive. Luckily, there are steps you can take to reduce wear and tear on your HVAC.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $66-$177 | |
| Condensor Cleaning | $1,328-$3,985 | |
| Thermostat Repair | $89-$221 | |
| Ductwork Cleaning | $425-$1,063 |
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 air conditioning and heating in your home.
Contact at least three HVAC providers for quotes. Explain your issues and schedule an in-person inspection if possible. Compare providers' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid companies that pressure you or demand upfront payment.
Choose an HVAC company with highly trained technicians who have proper 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, an individual 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 by the state.
HVAC contractors in California 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. Checking reviews on Google Reviews, Yelp, the Better Business Bureau (BBB), and similar sites can help your decision as well. Choose a company with great reviews and stories of positive experiences from customers.
Make sure you understand the details of any project before starting. For HVAC repairs, have your provider detail which parts need replacement and why. Get confirmation that your technician will clean and test the system after the repair to verify that everything works. When replacing your HVAC, ask the installation company to provide details on the new model, features, 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.
Reliable HVAC companies provide warranties for their services. Broader coverage is better, so make sure to compare warranties between companies. Choose the one that provides the most comprehensive coverage at a fair cost.
Get written quotes before starting any HVAC work. The quote should outline costs for both labor and materials. Read all terms carefully before signing.
Generally, your HVAC system should be inspected twice a year. After an inspection, your HVAC technician will tell you what services are required. You should also call a technician if you notice any new issues, such as strange noises, leaks, or unusual smells. If you have ductwork in your home, it should be serviced every few years.
The best times of the year to have an HVAC inspection are the spring and fall. Technicians tend to be less busy during these times, which makes it easier to get an appointment. This also ensures that your system is ready for the summer and winter, the times of the year when it 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 comfortably can, and 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 avoid letting cool air escape. Similarly, ensure that your attic is well ventilated to avoid trapping excess heat in your home.
Generally, HVAC installation or replacement takes between one and three days for the entire system. Installing or replacing a furnace or air conditioning unit can take as little as half a day or as much as two days. The exact amount of time will be based on things like how large your home is, how easily accessible different parts of the system are, and whether your technician runs into any problems.
For a 2,000-square-foot home, you'll need between 2.5 and 5 tons of air conditioning capacity. In Discovery Bay, you'll probably want to explore units on the higher end of this range. For a house over 1,000 square feet, central air is likely to be more effective than window units for cooling.
For a 2,000-square-foot home, you'll also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units). In Discovery Bay, you might be able to make do with a lower-capacity furnace.
There are several ways you can make your HVAC system more energy-efficient:
