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. Watch out for these common signs that your HVAC needs service:
If you notice any of these HVAC issues, have a technician inspect your system. A local professional can detect problems and let you know whether whether repairing or getting a new HVAC unit is the best solution.
The cost of HVAC installation or maintenance varies depending on the type of unit you have. Common types of HVAC units include the following:
HVAC maintenance costs differ depending on the particular service needed. HVAC systems are complex and can require different maintenance services. Fees for common services are as follows:
HVAC Unit Type | Cost | |
---|---|---|
Split | $2,049-$5,224 | |
Hybrid Split | $4,152-$7,650 | |
Heat Pump | $3,215-$32,762 | |
Packaged Heating and Air | $269-$448 |
Fixing your HVAC by repairing or replacing parts when needed is important, but can be costly. Thankfully, there are actions you can take to minimize wear and tear over time on your system.
Service | Cost | |
---|---|---|
Filter Replacement | $67-$179 | |
Condensor Cleaning | $1,345-$4,036 | |
Thermostat Repair | $90-$224 | |
Ductwork Cleaning | $430-$1,076 |
Finding the right HVAC company is key for a smooth installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.
Contact at least three HVAC providers for quotes. Explain the issues and have technicians visit to inspect your system if possible. Compare the providers' explanations, solutions, estimated costs, warranties, and timeframes. Avoid contractors that pressure you or demand payment upfront.
Look for an HVAC company that employs skilled technicians with the necessary licensure and training. 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 the type 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. Always check a company's reviews and complaints with organizations such as Google Reviews, the Better Business Bureau (BBB), and Yelp. Choose a provider with glowing reviews and stories of positive service experiences.
Always make sure you understand the details of any project. For HVAC repairs, your provider should list which parts require replacement and why. Confirm that your technician will clean and test the full system after repairs are completed to ensure that it’s working properly. When replacing your HVAC, request that the company explain the new model, brand, estimated installation time, features, and energy efficiency. Before signing a contract, be sure you understand how your provider will determine the right system size for your home and what the price will be.
A trustworthy HVAC company will stand behind its repair services and equipment installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully review warranty terms for each contractor and choose the provider that offers the greatest protection within your budget.
Always get HVAC quotes in writing before work begins. A comprehensive quote will cover costs for both materials and labor. Confirm that you understand all terms before signing the contract.
You should have your HVAC system inspected approximately twice a year. At the time of the inspection, your technician will inform you what services are required. You should also call a technician if you notice new issues such as unusual smells, leaks, or strange noises. If your home has ductwork, it should be inspected every few years.
Generally, it's best to schedule inspections in the spring and fall, as technicians tend to be less busy at these times. This also helps get your system ready for the summer and winter, when it probably 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 can, and avoid making drastic changes in temperature all at once. Keep your roof in good shape and seal any leaks around your windows and doors to avoid letting cool air escape. Similarly, ensure that your attic is well ventilated to avoid trapping excess heat in your home.
It takes around one to three days to have an 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 will be determined by the size of your home, the accessibility of your system, and any new issues your technician runs into.
For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. In Los Altos, you'll probably want to choose a unit that's on the higher end of this range. If your home is larger than 1,000 square feet, central air will generally 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 Los Altos, 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:
