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 having issues or getting near the end of its lifespan, it likely needs servicing or replacement from an HVAC company. Look for these indicators your system needs service:
Schedule an inspection if you notice any of these problems. A local technician can evaluate your system, detect problems, and decide whether you need to fix or replace your HVAC.
What you pay for HVAC installation or maintenance varies based on your system style. Common HVAC unit styles include the following:
HVAC maintenance costs vary based on the specific services required. HVAC systems can be complicated and potentially require a number of services. Fees for typical jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,808-$4,608 | |
| Hybrid Split | $3,663-$6,748 | |
| Heat Pump | $2,836-$28,900 | |
| Packaged Heating and Air | $237-$396 |
It’s important to make any essential HVAC fixes or replacements as needed, though they can be expensive. The good news is that homeowners have methods to decrease the effect of wear and tear and reduce the frequency of breakdowns.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $59-$158 | |
| Condensor Cleaning | $1,187-$3,560 | |
| Thermostat Repair | $79-$198 | |
| Ductwork Cleaning | $380-$949 |
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 air conditioning and heating for your home.
Contact at least three HVAC companies for quotes. Explain the issues and have technicians visit to inspect your HVAC system if possible. Compare the providers' explanations, solutions, estimated costs, warranties, and timeframes. Avoid providers that pressure you or demand payment upfront.
Look for an HVAC company that employs skilled technicians with 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 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 what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled by the state.
There are no state-level requirements for general HVAC licensing in Pennsylvania. However, there may be local licensing requirements or certifications required to work on specific projects. You can also verify whether a contracting company has a valid Pennsylvania business license. You should also check reviews and complaints on sites like the Better Business Bureau (BBB), Google Reviews, and Yelp. Choose a company with positive reviews and reports of great customer experiences.
It’s important to know what the work process will look like. For HVAC repairs, the company should explain the exact parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to ensure proper functioning. When replacing your HVAC, ask the contractor to describe the new estimated installation time, energy efficiency, brand, features, and model. Before work starts, 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 service and equipment installations. The more complete the coverage, the better. Compare warranty details between companies and pick the one that provides the best protection for the fairest price.
Get a written estimate before HVAC work starts. A full quote includes both materials and labor costs. Make sure you understand and accept all terms before signing the contract.
You should have your HVAC system inspected twice a year. At the time of the inspection, your technician will tell you what services are required. You should also schedule an inspection if you start noticing issues such as strange noises, leaks, or unusual smells. If your home has ductwork, you should have it inspected every few years.
Usually, it's best to 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 probably sees the most use.
You can save energy throughout the year by reducing the amount of power your HVAC system uses to maintain the temperature of your home. During all seasons, keep your thermostat as close to the outside temperature as possible, and try to adjust it only a few degrees at a time. You might also consider getting a smart thermostat.
For a 2,000-square-foot home, look for a furnace that's between 50,000 and 80,000 BTUs (British thermal units).
For a 2,000-square-foot home, you'll also want an air conditioning unit with around 2.5 to 5 tons of capacity. Generally, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.
Your HVAC company might provide financing options through a third-party lender, or you might be able to obtain a loan on your own. It's a good idea to discuss payment options with your HVAC company and a financial advisor to make sure that you find the best option for you.
There are several ways you can make your HVAC system more energy-efficient:
