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:
If your HVAC system is faulty or getting near the end of its lifespan, it likely needs servicing or replacement from an HVAC company. Look for these signs your system needs service:
Book an inspection if you notice any of these issues. A local technician can assess your system, detect problems, and decide whether you need to fix or replace your HVAC.
Your HVAC installation or maintenance cost varies depending on the style of unit. Common HVAC unit types include the following:
HVAC maintenance costs differ depending on what services are needed. HVAC systems are complex and can require different maintenance services. Prices for common services are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,830-$4,665 | |
| Hybrid Split | $3,708-$6,831 | |
| Heat Pump | $2,871-$29,253 | |
| Packaged Heating and Air | $240-$400 |
Repairing or replacing your HVAC system when needed is important, but can be expensive. Thankfully, there are steps you can take to minimize wear and tear over time on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $60-$160 | |
| Condensor Cleaning | $1,201-$3,604 | |
| Thermostat Repair | $80-$200 | |
| Ductwork Cleaning | $384-$961 |
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 fix your system, providing you with effective air conditioning and heating for your home.
Get quotes from at least three HVAC contractors. Explain your issues and ask if technicians can inspect your system in person. Compare each provider's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid contractors that pressure you or demand payment before work.
When hiring 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 mandatory 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 by the state.
HVAC contractors in Texas are required to be licensed by the Texas Department of Licensing and Regulation. Contractors need to have at least four years of experience within the past six years and must provide proof of insurance. An individual can also be a registered technician, which has no experience requirements, or a certified technician, which requires two years of experience. Registered and certified technicians must both be supervised by a licensed contractor. Also look at a company's reviews and complaints on sites such as Google Reviews, the Better Business Bureau (BBB), and Yelp. Pick a company with glowing feedback and stories of satisfied customers.
Always make sure you know what a company’s process is like. When getting HVAC repairs, ask your provider to explain which parts require replacement and explain why. Confirm that your technician will clean and test the full system at the end of the job to ensure proper operation. When replacing your HVAC system, ask the installation company to provide details on the new estimated installation time, brand, features, model, and energy efficiency. Before work begins, 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 offer warranties on repairs and installations. The more complete the coverage, the better. Review warranty details between companies and pick the one that offers the best protection for a fair price.
Always get quotes for HVAC service in writing before committing to a provider. A detailed quote should cover both labor and materials. Make sure you understand all terms before signing a contract.
You should have your HVAC system inspected about twice a year. Following an inspection, your technician will inform you if any services are required. You should also call a technician if you notice new issues such as strange noises, unusual smells, or leaks. If your system has ductwork, you should have it inspected every few years.
Normally, it's a good idea to have your HVAC system inspected 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 typically sees 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 is comfortable, and try to avoid making drastic changes in temperature all at once. Keep your roof in good shape and seal any window or door leaks to avoid letting cool air escape. Similarly, ensure that 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 anywhere from a few hours up to two days. This timeline will be affected by the size of your home, how easily accessible your system is, and any issues your technician runs into.
For a 2,000-square-foot home, you'll need between 2.5 and 5 tons of air conditioning capacity. In Waco, 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 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 Waco, you might 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:
