Knowing what to look for in an HVAC company is important for a successful project. Look for an experienced, licensed contractor that can give you peace of mind and ensure your system provides reliable heating and air conditioning for your home.
Request estimates from three or more HVAC providers. Explain your issues and ask if specialists 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. HVAC contractors in all states 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 intend 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.
Normally, all Montana contractors must register with the Department of Labor and Industry. Independent contractors can apply for exemption. If a company has employees, it must have workers' compensation insurance. 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 starting. For HVAC repairs, have your provider specify which parts need replacement and why. Confirm that your technician will clean and test the entire system after the repair to verify that everything works. When replacing your HVAC, ask the provider to explain the new energy efficiency, estimated installation time, brand, model, and features. Before signing paperwork, make sure you understand how your provider will determine the right system size for your home and what the price will be.
Reliable HVAC companies provide warranties for their work. The broader the coverage, the better, so make sure to review warranties between companies. Choose the one that gives you the most coverage at a fair cost.
Always get HVAC estimates in writing before work begins. A comprehensive quote will cover costs for both labor and materials. Ensure that you understand all terms before signing the contract.
You should have your HVAC system inspected twice yearly. After the inspection, your technician will inform you what services are required. You should also call a technician if you notice new issues such as strange noises, leaks, or unusual smells. If your system has ductwork, it should be inspected every few years.
Usually, you should 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 typically 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 is comfortable and don't make drastic changes in the temperature — increase or decrease it a few degrees at a time. If you're able to, try switching to a smart thermostat.
Generally, HVAC installation or replacement takes one to three days for the entire system. Installing or replacing a furnace or air conditioning unit takes anywhere from about half a day up to two days. The exact amount of time will vary depending on things like the size of your house, how easily accessible different areas are, and whether your technician finds any problems.
Usually, HVAC financing is through a third-party lender. If your HVAC company doesn't offer these options, you could consider taking out a loan on your own. Be sure to speak with a financial advisor and your HVAC company to find out what options are available to you and appropriate for your situation.
There are several ways you can make your HVAC system more energy-efficient:
