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 maintenance or replacement. Watch for these signs that your system needs service:
If you notice any of these HVAC red flags, your system evaluated. A local company can complete an inspection, diagnose problems, and recommend repairing or replacing your HVAC unit.
The cost of HVAC installation or maintenance varies depending on the kind of unit you have. Common types of HVAC units include the following:
The amount you spend on HVAC maintenance also varies depending on the kind of work you're having done. HVAC systems are complex and might require different kinds of maintenance. The prices of some common jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,886-$4,808 | |
| Hybrid Split | $3,822-$7,041 | |
| Heat Pump | $2,959-$30,153 | |
| Packaged Heating and Air | $248-$413 |
Taking care of necessary HVAC repairs and replacements when needed is crucial, but can be costly. Luckily, there are steps you can take to minimize wear and tear over time on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $62-$165 | |
| Condensor Cleaning | $1,238-$3,714 | |
| Thermostat Repair | $83-$206 | |
| Ductwork Cleaning | $396-$991 |
Finding the right HVAC company is vital for an easy installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide reliable heating and air conditioning year-round.
Contact at least three HVAC companies for quotes. Describe your issues and schedule an in-person inspection if possible. Compare companies' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand upfront payment.
Choose an HVAC company with well-trained technicians who have appropriate licensing and experience. In all states, HVAC contractors have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, a contractor must pass an exam (the specific exam depends on the kind of equipment they plan 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 by the state.
All HVAC contractors in Georgia must be licensed. They may hold a Class I or Class II license. A Class I license requires four years of experience and limits the type of equipment a contractor can work on. A Class II license requires five years of experience and is unrestricted. Licenses can be verified on the Secretary of State's website. Checking reviews on Yelp, the Better Business Bureau (BBB), Google Reviews, and similar sites can assist your decision. Choose a provider with stellar reviews and reports of positive experiences from customers.
It’s important to know what the work process is going to look like. For HVAC repairs, the company should explain the particular parts that need replacement and why. Get confirmation that your technician will clean and test your system afterward to ensure proper functioning. When getting a replacement, ask the contractor to explain the new HVAC system estimated installation time, energy efficiency, features, model, and brand. Before work begins, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.
Reputable HVAC companies back their work with warranties. Look at warranties from different companies, while remembering that broader coverage is better. Look for the provider that offers the most coverage for a fair price.
Get a written proposal before HVAC work starts. A comprehensive quote includes both labor and material costs. Make sure you understand and accept all terms before signing the contract.
You should have your HVAC system inspected about twice a year. At the time of the inspection, your technician will inform you what services are needed. You should also have your system inspected if you notice new issues such as leaks, unusual smells, or strange noises. If your system has ductwork, it should be inspected every few years.
Generally, it's smart to schedule inspections in the spring and fall, as these times tend to be less busy. This also helps get your system ready for the summer and winter, when it likely 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 is comfortable, 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, HVAC installation or replacement takes one to three days for the entire system. Installing or replacing a furnace or air conditioning unit can take as little as half a day or as much as two days. The exact amount of time will depend on things like the size of your house, how easily accessible different sections are, and whether your technician finds any problems.
For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. In LaGrange, 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 will generally be more effective for cooling than window units.
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 LaGrange, you might be able to make do with a lower-capacity furnace.
Normally, HVAC financing is provided by a third-party lender. If your HVAC company doesn't offer financing, you may consider taking out your own loan. Be sure to talk to your HVAC company and a financial advisor to determine what options are available to you and appropriate for your situation.
