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 indicators that your HVAC needs service:
If you notice any of these HVAC issues, we recommend having a technician inspect your system. A local professional can diagnose problems and let you know whether whether fixing or replacing your HVAC unit is the best solution.
Your HVAC installation or maintenance cost changes depending on the type of unit. Common HVAC unit varieties include the following:
HVAC maintenance costs vary based on the specific services needed. HVAC systems can be complex and potentially require several different services. Price ranges 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 |
HVAC system repairs and replacements are important, but can be pricey. Fortunately, there are steps homeowners can take to reduce wear and tear on their HVAC and lower future maintenance needs.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $63-$168 | |
| Condensor Cleaning | $1,259-$3,777 | |
| Thermostat Repair | $84-$210 | |
| Ductwork Cleaning | $403-$1,007 |
Knowing what makes a trustworthy HVAC company is crucial for a smooth installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.
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.
When looking for an HVAC provider, choose one with technicians that have the right training, licenses, and experience. In all states, HVAC contractors must 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 what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled at the state level.
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, and contractors with employees must also meet insurance requirements. You should also read reviews and complaints on sites like Google Reviews, the Better Business Bureau (BBB), and Yelp. Pick a company with positive reviews and testimonials about fantastic customer experiences.
It’s important to understand what the work process is going to look like. For HVAC repairs, the company should list the particular parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to make sure everything is operating properly. When replacing your HVAC, ask the contractor to describe the new model, brand, estimated installation time, features, and energy efficiency. Before work starts, ask about the process your provider will use to properly size the new system for your home and how much it will cost.
Reliable HVAC companies provide warranties for their services. Broader coverage is better, so make sure to review warranties between providers. Choose the one that offers the best coverage at a fair cost.
Get a written quote before HVAC work starts. A full quote includes both labor and material costs. Make sure you understand and agree to all terms before signing the contract.
Typically, you should have your HVAC system inspected twice a year. After an inspection, your HVAC technician will tell you what services are needed. You should also call a technician if you notice any new 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 your HVAC system inspected are the spring and fall. Technicians are generally less busy during these times, which makes it easier to get an appointment. This also helps get your system ready 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 try to avoid making drastic changes in temperature all at once. Keep your roof well-maintained and seal any door or window leaks to help keep cool air in. Similarly, ensure that your attic is well ventilated to avoid trapping excess heat in your home.
Generally, whole-system HVAC installation or replacement takes one to three days. Installing or replacing a furnace or air conditioning unit may take anywhere from a few hours up to two days. The exact amount of time will depend on factors like how large your home is, how easily accessible different sections are, and whether your technician discovers any problems.
For a 2,000-square-foot home, you'll need between 2.5 and 5 tons of air conditioning capacity. In Lancaster, you'll probably want to explore units on the higher end of this range. If your home is larger than 1,000 square feet, central air will 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 Lancaster, you may be able to make do with a lower-capacity furnace.
There are a number of ways you can make your HVAC system more energy-efficient:
