Do both my boiler and water heater need their own expansion tank?

• <div><p>Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater. </p></div>

Is it worth it to repair an HVAC system, or should I replace it?

• <div><p>It is usually worth it to repair your HVAC system instead of replacing it. However, one exception is if your system is reaching the end of its life—usually 15 to 25 years. Otherwise, repairs will cost an average of <b>$350</b>, and a <a href="https://www.angi.com/articles/insider-s-price-guide-new-heating-and-cooling-system.htm">full HVAC replacement would total</a> <b>$7,500</b> in most cases, or between <b>$5,000 and $22,000</b>, depending on the type of system. A reputable HVAC repair company can inspect your system and let you know if replacing it would be more cost-effective. </p></div>

Do HVAC repair companies need to be licensed?

• <div><p>Many states don’t have specific license requirements for HVAC repair companies, but your local city or county might. You can check online for local requirements and then Angi’s <a href="https://www.angi.com/angi-license-check.htm">contractor licensing tool</a> to see if the company you’re considering is licensed. Regardless of licensing, you should ensure your company is fully insured. We recommend checking to see if the company holds third-party certifications, including North American Technician Excellence (NATE) certification and R-410A certification, which qualifies your provider to work with HVAC refrigerants.</p></div>

There's nothing worse than the A/C failing the first time it gets really hot. Monica replied quickly, and Don was out on time. We anticipated a big problem since this was a rental property and the previous renter had "fixed" the furnace on his own, which affected the A/C Don fixed it with...
