Q: Should you tip HVAC technicians?

• <div><p>It&rsquo;s not customary to tip HVAC technicians, and most professionals won&rsquo;t expect it. However, it&rsquo;s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren&rsquo;t expected.</p></div>

Q: Can you run a window unit and central air together?

• <div><p>Though it may seem redundant, you can absolutely have a central AC unit and a window AC in your home. In fact, if you place a window AC unit near your central air, it can help move the cooler air throughout your home. But doubling up on your AC methods can get pricey, so factor in cost accordingly.</p></div>

Q: What are the signs of mold in an air conditioner?

• <div><p>One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.</p></div>

Q: How much does it cost to replace an AC evaporator or condenser coil?

• <div><p>The cost to replace an AC evaporator coil is typically between $600 and $2,500, with an average cost around $1,300 to $1,350. The price of the coil itself can range from $550 to $1,100, depending on the brand, size, and style, with professional labor adding around $700. Replacing a condenser coil is generally less expensive, costing about $800. Because this repair involves handling refrigerants, it requires a licensed AC professional. Regular inspections, which cost between $200 and $600, can help prevent costly coil replacements.</p></div>

Q: Is it bad to turn AC on and off frequently?

• <div><p>No, it isn&rsquo;t necessarily <a href="https://www.angi.com/articles/is-it-bad-to-keep-turning-ac-on-and-off.htm">bad to turn your AC on and off</a> frequently&mdash;contrary to popular belief. Even if you stop and start your AC throughout the day, it won&rsquo;t use as much energy as it would if you ran it nonstop. </p><p>If you&rsquo;re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.</p></div>

"Tim and Jeff were very fastidious in setting up, cleaning, and making sure the house was in good order when they left . We also had an Aeroseal treatment which followed with James and Connor. It did take some time to set up after the vents were cleaned and blown out, but the application of this polymer to close gaps in lthe galvinized steel ducts was remarkable."
