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:
A malfunctioning or aging HVAC system probably needs attention from a professional who can make fixes or install a new unit. Look out for these common indicators that your HVAC needs service:
If you notice any of these HVAC red flags, your system evaluated. A local provider can complete an inspection, identify problems, and advise you whether you should repair or replace your HVAC unit.
The cost of HVAC installation or maintenance varies depending on the type of unit you have. Common kinds of HVAC units include the following:
The price of HVAC maintenance also depends on the kind of work being done. HVAC systems are complex and can require different kinds of maintenance. The prices of some common jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,794-$4,574 | |
| Hybrid Split | $3,636-$6,698 | |
| Heat Pump | $2,815-$28,684 | |
| Packaged Heating and Air | $236-$393 |
Repairing or replacing your HVAC system when needed is crucial, 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 | $59-$157 | |
| Condensor Cleaning | $1,178-$3,533 | |
| Thermostat Repair | $79-$196 | |
| Ductwork Cleaning | $377-$942 |
Knowing the indicators of a reliable HVAC company is key for a smooth repair or installation. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent coolig and heating year-round.
Contact at least three HVAC companies for quotes. Explain your issues and schedule an in-person inspection if possible. Compare providers' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid companies that pressure you or demand upfront payment.
Look for an HVAC company that employs skilled technicians who have the necessary training and licenses. HVAC contractors in all states must 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 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 Oklahoma, HVAC contractors are required to be licensed by the Oklahoma Construction Industries Board. To work on HVAC projects, a contractor can have an HVAC/R limited license (which allows them to work on only small jobs) or an HVAC/R unlimited license (which allows them to work on all jobs). Individuals need to have four years of experience and must pass an exam to become fully licensed contractors. Always check a provider's reviews and complaints with organizations such as the Better Business Bureau (BBB), Google Reviews, and Yelp. Choose a provider with glowing reviews and stories of positive service experiences.
It’s important to know what the work process is going to look like. For HVAC repairs, the company should detail the particular parts that need replacement and why. Confirm that your technician will clean and test the full system afterward to ensure proper functioning. When replacing your HVAC, have the provider describe the new features, model, brand, estimated installation time, and energy efficiency. Before signing a contract, ask about the process your provider will use to properly size the new system for your home and how much it will cost.
Reliable HVAC companies offer warranties on repairs and equipment installations. The more complete the coverage, the better. Review warranty details between companies and pick the one that offers the best protection within your budget.
Always get HVAC bids in writing before work begins. A thorough quote covers costs for both materials and labor. Make sure that you agree to all terms before signing the contract.
You should have your HVAC system inspected about twice yearly. At the time of the inspection, your technician will tell you what services are needed. You should also have your system inspected if you start noticing issues such as leaks, unusual smells, or strange noises. If your home has ductwork, you should have it inspected every few years.
Generally, you should have your HVAC system inspected in the spring and fall, as these times tend to be less busy. This also helps make sure your system is prepared 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 avoid making drastic changes in temperature all at once. Keep your roof well-maintained and seal any leaks around your windows and doors to avoid letting cool air escape. 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 a furnace or a single air conditioning unit, this might 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 issues your technician uncovers.
For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. In Collinsville, you'll probably want to choose a unit that's on the higher end of this range. For a house over 1,000 square feet, central air will 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 Collinsville, you may 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:
