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 home's HVAC system isn't working correctly or nearing the end of its lifespan, you might need an HVAC contractor for repairs or replacement. Look for these common signs that your system requires professional attention:
If you're experiencing any of these HVAC issues, have a technician inspect your system. A local professional can identify problems and let you know whether whether fixing or replacing your HVAC unit is the best solution.
What you spend on HVAC installation or maintenance depends on your system style. Common HVAC unit styles include the following:
HVAC maintenance costs vary based on the specific services needed. HVAC systems can be complicated and potentially require a number of services. Price ranges for typical jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,907-$4,862 | |
| Hybrid Split | $3,865-$7,120 | |
| Heat Pump | $2,992-$30,492 | |
| Packaged Heating and Air | $250-$417 |
Essential HVAC maintenance is important, but can be pricey. Thankfully, homeowners can take steps to reduce wear and tear on their system and lower future maintenance needs.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $63-$167 | |
| Condensor Cleaning | $1,252-$3,756 | |
| Thermostat Repair | $83-$209 | |
| Ductwork Cleaning | $401-$1,002 |
Knowing what to look for in an HVAC company is important for a successful project. Look for an experienced, licensed contractor that can give you peace of mind and make sure your system provides reliable heating and air conditioning for your home.
Contact at least three HVAC providers for quotes. Describe the issues and have technicians visit to inspect your HVAC system if possible. Compare the contractors' explanations, solutions, estimated costs, warranties, and timeframes. Avoid providers that pressure you or demand payment upfront.
Choose an HVAC company with skilled technicians who have proper licensing and experience. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, contractors must pass an exam (the specific exam depends on the kind of equipment they intend to work with). Section 608 certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." All other licensing requirements are handled at the state level.
HVAC contractors and subcontractors in Mississippi are required to be licensed by the Mississippi State Board of Contractors. To be licensed, contractors need to provide proof of general liability insurance, as well as workers' compensation insurance if they have above a certain number of employees. You should also read reviews and complaints on sites like the Better Business Bureau (BBB), Google Reviews, and Yelp. Pick a company with glowing reviews and reports of good customer experiences.
Always make sure you understand what a company’s process is like. When HVAC repairs are needed, ask your provider to list which parts require replacement and explain why. Confirm that your technician will clean and test the system after finishing the work to verify proper operation. When getting a replacement, ask the contractor to explain the new HVAC system brand, energy efficiency, model, features, and estimated installation time. Before starting the project, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.
Good HVAC companies offer warranties on repairs and equipment installations. The more complete the coverage, the better. Compare warranty details between companies and pick the one that offers the best protection for the fairest price.
Always get estimates for HVAC service in writing before work begins. A comprehensive quote should cover both labor and materials. Make sure you agree to all terms before signing a contract.
Typically, your HVAC system should be inspected twice a year. After that inspection, your HVAC technician will tell you what services are required. You should also call a technician if you start to notice any issues, like leaks, strange noises, or unusual smells. If your home has ductwork, it should be serviced every few years.
The best times 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, when it typically gets 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 you comfortably can, and try to avoid making drastic changes in temperature all at once. Keep your roof well-maintained and seal any leaks around your doors and windows 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 between one and 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 things like the size of your home, how easily accessible different areas are, and whether your technician discovers any problems.
For a 2,000-square-foot home, look for a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In Madison, you may be able to make do with a lower-capacity furnace.
For a 2,000-square-foot home, you'll also want an air conditioning unit with around 2.5 to 5 tons of capacity. In Madison, you'll likely look for something on the higher end of this range. Usually, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.
Typically, HVAC financing is provided by a third-party lender. If your HVAC company doesn't have financing options, you could consider taking out a loan on your own. Be sure to speak with a financial advisor and your HVAC company to find out what options are available and appropriate for your situation.
There are a number of ways you can make your HVAC system more energy-efficient:
