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:
An HVAC system that's not working properly or old likely needs professional attention for repairs or replacement. Watch for these signals that your system needs service:
If you notice any of the above, have a local HVAC technician inspect your system. They can diagnose problems and recommend whether repair or full HVAC replacement is required.
HVAC installation or maintenance costs change depending on your system. Common HVAC unit varieties include the following:
HVAC costs differ based on the services needed. HVAC systems are complicated and may need several types of maintenance. Costs for common jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,764-$4,496 | |
| Hybrid Split | $3,573-$6,583 | |
| Heat Pump | $2,767-$28,194 | |
| Packaged Heating and Air | $232-$386 |
Essential HVAC maintenance is important, but can be pricey. Luckily, there are steps homeowners can take to reduce wear and tear on their system and lower future maintenance needs.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $58-$154 | |
| Condensor Cleaning | $1,158-$3,473 | |
| Thermostat Repair | $77-$193 | |
| Ductwork Cleaning | $370-$926 |
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 keep your system running efficiently, providing you with effective heating and cooling in your home.
Contact at least three HVAC companies 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.
When looking for an HVAC company, choose one with technicians that have the proper 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." Contractors 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.
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 look at reviews and complaints on sites like the Better Business Bureau (BBB), Google Reviews, and Yelp. Pick a company with positive reviews and reports of good customer experiences.
Make sure you know the details of any project before starting. For HVAC repairs, have your provider specify which parts need replacement and why. Confirm that your technician will clean and test the entire system after the repair to ensure that everything works. When replacing your HVAC system, ask your contractor to provide details on the new energy efficiency, model, brand, features, and estimated installation time. 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.
Trustworthy HVAC companies provide warranties for their work. Broader coverage is better, so make sure to compare warranties between companies. Choose the one that offers the best coverage at a reasonable cost.
Get written estimates before beginning HVAC work. The quote should outline costs for both materials and labor. Review all terms carefully before signing.
Normally, your HVAC system should be 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, like leaks, strange noises, or unusual smells. If your home has ductwork, it should be serviced every few years.
The best times of the year to have an HVAC inspection are during the spring and fall. Technicians are less busy during these times, so it will be 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 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 comfortably can, and avoid making drastic changes in temperature all at once. Keep your roof in good shape and seal any window or door leaks to help keep cool air in. Similarly, ensure that your attic is well ventilated to avoid trapping excess heat in your home.
It takes between one and three days to have an HVAC system installed or replaced. If you only need an air conditioning unit or a furnace, this can take between half a day and two days. This timeline will be influenced by the size of your home, the accessibility of your system, and any new issues your technician discovers.
For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. In Dothan, 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 usually 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 Dothan, you might be able to make do with a lower-capacity furnace.
Your HVAC company might have financing options via a third-party lender, or you might be able to obtain your own loan. It's smart to discuss payment options with your HVAC company and a financial advisor to make sure that you're choosing the best option for you.
