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 broken or getting old, it likely needs servicing or replacement from an HVAC company. Watch for these indicators your system needs service:
If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can identify problems and determine whether repair or full HVAC replacement is the better solution.
Your HVAC installation or maintenance cost varies depending on the style of unit. Common HVAC unit types include the following:
HVAC maintenance costs vary depending on what services are needed. HVAC systems are complex and can require different kinds of maintenance. Costs for some common services are as follows:
HVAC Unit Type | Cost | |
---|---|---|
Split | $1,985-$5,061 | |
Hybrid Split | $4,023-$7,411 | |
Heat Pump | $3,115-$31,739 | |
Packaged Heating and Air | $261-$434 |
Essential HVAC maintenance is important, but can be pricey. Luckily, homeowners can take steps to reduce wear and tear on their HVAC and lower future maintenance needs.
Service | Cost | |
---|---|---|
Filter Replacement | $65-$174 | |
Condensor Cleaning | $1,303-$3,910 | |
Thermostat Repair | $87-$217 | |
Ductwork Cleaning | $417-$1,043 |
Knowing the right things to look for in an 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.
Get quotes from three or more HVAC companies. Describe your issues and ask if technicians can inspect your system in person. Review each provider's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid providers that pressure you or demand payment before work.
It's important to choose an HVAC company that employs technicians with the proper qualifications and expertise. 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 type of 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 at the state level.
There are no state-level licensing requirements for HVAC technicians in Massachusetts. However, HVAC technicians who do certain cooling work may need a Refrigeration Technician License for larger projects.
You should also check with your city or municipal government to learn if HVAC contractors have any local licensing requirements. You should also check reviews and complaints on sites like the Better Business Bureau (BBB), Yelp, and Google Reviews. Choose a company with glowing reviews and reports of fantastic customer experiences.
It’s important to understand what the work process will look like. For HVAC repairs, the company should explain the particular parts that need replacement and why. Confirm that your technician will clean and test your system afterward to make sure everything is operating properly. When replacing your HVAC system, ask the installation company to provide details on the new features, brand, model, estimated installation time, and energy efficiency. Before signing a contract, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.
Trustworthy HVAC companies stand behind their work with warranties. Compare warranties from different companies, remembering that more comprehensive coverage is better. Look for the company that provides the most coverage for a reasonable price.
Get written quotes before starting any HVAC work. The quote should outline costs for both labor and materials. Read all terms carefully before signing.
You should have your HVAC system inspected approximately twice yearly. After the inspection, your technician will inform you what services are required. 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, you should have it inspected every few years.
Normally, it's a good idea to have your HVAC system inspected 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 probably sees the most use.
You can save energy during the winter by reducing how much power your HVAC system uses to heat your home. Keep your thermostat as low as you can and don't make drastic temperature changes — only increase or decrease it a few degrees at a time. If possible, try switching to a smart thermostat.
Generally, whole-system HVAC installation or replacement takes one to three days. Installing or replacing an air conditioning unit or a furnace may take anywhere from a few hours up to two days. The exact amount of time will be based on things like the size of your home, how easily accessible different areas are, and whether your technician runs into any problems.
For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. In Dennis, you'll probably be fine with a unit that's on the lower end of this range. For homes over 1,000 square feet, central air will 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).
There are several ways you can make your HVAC system more energy-efficient:
