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 broken or getting old, it likely needs servicing or replacement from an HVAC company. Look for these signs your system needs service:
If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can diagnose problems and determine whether repair or full HVAC replacement is needed.
What you spend on HVAC installation or maintenance is determined by your system type. Common HVAC unit styles include the following:
The price of HVAC maintenance also varies depending on the kind of work being done. HVAC systems are complex and may require different kinds of maintenance. The prices of some common jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,829-$4,662 | |
| Hybrid Split | $3,706-$6,827 | |
| Heat Pump | $2,869-$29,238 | |
| Packaged Heating and Air | $240-$400 |
HVAC system repairs and replacements are important, but can be expensive. Luckily, there are steps homeowners can take to reduce wear and tear on their system and lower future maintenance needs.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $60-$160 | |
| Condensor Cleaning | $1,201-$3,602 | |
| Thermostat Repair | $80-$200 | |
| Ductwork Cleaning | $384-$960 |
Knowing the indicators of a good HVAC company is important. A properly licensed contractor with the right experience will give you confidence that they can maintain your HVAC system properly, providing you with effective heating and cooling for your home.
Get quotes from three or more HVAC contractors. Describe your issues and ask if technicians can inspect your system in person. Review each contractor's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid providers that pressure you or demand payment before work.
Look for an HVAC company that employs qualified technicians who have the necessary training and licenses. 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 contractors who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." Contractors 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 Alabama, HVAC contractors are required to be licensed by the Board of Heating, Air Conditioning and Refrigeration Contractors. Contractors need to hold a surety bond and must complete a set number of continuing education hours each year. You should also read reviews and complaints on sites like Google Reviews, the Better Business Bureau (BBB), and Yelp. Choose a company with glowing reviews and reports of good customer experiences.
Always make sure you understand what a company’s process looks like. When getting HVAC repairs, ask your provider to specify which parts require replacement and explain why. Confirm that your technician will clean and test your system after finishing the work to guarantee proper operation. When replacing your HVAC, ask the provider to explain the new features, brand, energy efficiency, estimated installation time, and model. Before signing paperwork, 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.
Reliable HVAC companies offer warranties on service and installations. The more complete the coverage, the better. Review warranty details between providers and pick the one that offers the most comprehensive protection within your budget.
Always get HVAC bids in writing before work begins. A thorough quote covers costs for both materials and labor. Ensure that you understand all terms before signing the contract.
Generally, your HVAC system should be inspected twice a year. After an inspection, your HVAC technician will tell you what, if any, services are required. You should also have your system inspected and serviced if you start to notice any issues, such as leaks, unusual smells, or strange noises. 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 often 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, which is when it normally 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 well-maintained and seal any door or window leaks to help keep cool air in. Similarly, make sure 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 an air conditioning unit or a furnace may take anywhere from a few hours up to two days. The exact amount of time will be based on things like the size of your home, how easily accessible different areas are, and whether your technician finds any problems.
For a 2,000-square-foot home, you'll want a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In Foley, you may be able to make do with a furnace on the lower end of this range.
For a 2,000-square-foot home, you'll also want to purchase an air conditioning unit with around 2.5 to 5 tons of capacity. In Foley, you'll likely need something on the higher end of this range. In general, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.
Your HVAC company may provide financing options through a third-party lender, or you may choose to obtain your own loan. It's smart to discuss payment options with a financial advisor and your HVAC company to make sure that you're choosing the best option for you.
There are a number of ways you can make your HVAC system more energy-efficient:
