Q: How do I know if my AC needs a tune-up?

• <div><p>The simplest indicator is how long it&rsquo;s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.</p></div>

Q: How do I reset my air conditioner?

• <div><p>To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Next, find the &ldquo;reset&rdquo; button on your AC unit and hold it for three to five seconds. The unit should beep several times. If your air conditioner doesn&rsquo;t have a reset button, leave the circuit breaker off for 30 minutes. Afterward, turn the power back on at the breaker and program the thermostat to &ldquo;cool&rdquo; to test the system.</p></div>

Q: Do all portable air conditioners have to be vented out a window?

• <div><p>Not necessarily. Some portable air conditioners may be vented out a door, wall, or ceiling&mdash;or even into another room. It&rsquo;s not necessarily dangerous to run a portable air conditioner without venting it, but it is counterproductive since the unit needs to vent the heat in order to cool the room down in the first place. Without venting your portable AC unit, you&rsquo;re essentially running a dehumidifier and increasing the temperature in the room. </p></div>

Q: Can a frozen evaporator coil cause damage?

• <div><p>A frozen coil can cause permanent damage to your HVAC system and lead to costly repairs if not fixed. It can cause the unit to overheat and also cause the compressor to fail. It&rsquo;s vital to turn the unit off if the coil is frozen and address the issue as soon as possible. </p></div>

Q: How long does it take to fix an air conditioner?

• <div><p>Most AC repair technicians will take between <b>two and six hours</b> to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.</p></div>

Absolutely loved these guys!!! They went FAR ABOVE AND BEYOND for us working on our OLD water heater. I have no doubt than any other plumber would have just given up and said "Buy a new one!" But not these guys. Saved me a bunch of money!!! I'll definitely be using them in the future.

Our heat pump blower was not working at all. Even though it was the day after Thanksgiving, John Providenti didn't hesitate to come out on a service call. When he arrived he knew exactly what to look for and found a blown capacitor. He had the correct replacement part in his truck and was able...
