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 professional attention from a technician who can make repairs or install a new unit. Watch out for these common indicators that your HVAC needs service:
Arrange an inspection if you notice any of these problems. A local technician can evaluate your system, detect problems, and determine whether you need repairs or a new HVAC unit.
What you pay for HVAC installation or maintenance is determined by your system style. Common HVAC unit styles include the following:
HVAC costs differ based on the services needed. HVAC systems are complicated and may need several types of maintenance. Prices for common jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,792-$4,569 | |
| Hybrid Split | $3,632-$6,691 | |
| Heat Pump | $2,812-$28,655 | |
| Packaged Heating and Air | $235-$392 |
It's important to take care of HVAC repairs and replacements in a timely manner, but it can also be expensive. Fortunately, there are some steps you can take to reduce wear and tear on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $59-$157 | |
| Condensor Cleaning | $1,177-$3,530 | |
| Thermostat Repair | $78-$196 | |
| Ductwork Cleaning | $377-$941 |
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 fix your system, providing you with effective heating and cooling in your home.
Request estimates from three or more HVAC contractors. Explain your issues and ask if technicians can inspect your system in person. Compare each contractor's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid companies that pressure you or demand payment before work.
Choose an HVAC company with highly trained technicians who have proper licensing and experience. In all states, HVAC contractors have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, contractors must pass an exam (the specific exam depends on what 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 at the state level.
In Michigan, HVAC contractors are required to be licensed as Mechanical Contractors by the Department of Licensing and Regulatory Affairs (LARA). Contractors need to have at least three years of experience and must pass an exam. Licenses can be verified on LARA's website. Always check a provider's reviews and complaints with organizations such as Google Reviews, the Better Business Bureau (BBB), and Yelp. Look for a a provider with glowing reviews and stories of positive service experiences.
Make sure you understand the details of your project before it begins. If HVAC repairs are required, have your provider list which parts require replacement and why. Confirm that your technician will clean and test your system after the repair to verify that everything works. For replacement, ask your contractor to explain the new HVAC system features, energy efficiency, estimated installation time, brand, and model. Before signing a contract, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.
A trustworthy HVAC company will back its repair work and equipment installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully compare the fine print between contractors and choose the company that provides the best protection within your budget.
Always get estimates for HVAC service in writing before committing to a provider. An itemized quote should cover both materials and labor. Make sure you review all terms before signing a contract.
You should have your HVAC system inspected approximately twice yearly. Following an inspection, your technician will inform you what services are needed. You should also call a technician if you notice new issues such as leaks, strange noises, or unusual smells. If your system has ductwork, it should be inspected every few years.
Usually, it's smart to have your HVAC system inspected in the spring and fall, as technicians tend to be less busy at these times. This also helps get your system ready for the summer and winter, when it typically sees the most use.
You can save energy during the winter by reducing the amount of work your HVAC system needs to do to heat your home. Keep your thermostat as low as you can and avoid making drastic changes in the temperature — only increase or decrease it a few degrees at a time. If you can, try switching to a smart thermostat.
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 can take anywhere from a few hours up to two days. This timeline can be affected by the size of your house, how easily accessible your system is, and any issues your technician runs into.
For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. In Bangor, you can probably make do with a unit that's on the lower end of this range. If your home is larger than 1,000 square feet, central air is likely to be more effective than window units for cooling.
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).
Normally, HVAC financing is provided by a third-party lender. If your HVAC company doesn't offer financing, you might consider taking out a loan on your own. Be sure to talk to a financial advisor and your HVAC company to find out what options are available to you and appropriate for your situation.
There are a number of ways you can make your HVAC system more energy-efficient:
