"Allied Electric installed some Patio heaters for me, which also required upgrades to my electric panel. The entire process went smoothly and quickly - about a week from first engagement to job completion, and that included local permitting (which Allied managed) around the holiday weekend. Everyone I interacted with was friendly and knowledgeable, from Amber in the office, to Marioâ s inspection and quote, to Luisâ and Codyâ s installation. We are really enjoying being able to use our patio in the wintertime- Many thanks to the friendly Proâ s at Allied Electric!"

"Brian, the owner of the company was fantastic and friendly. We had him clean out two dryer vents and he even came out on a Saturday with a short notice. Would absolutely recommend him! Lastly, he pulled out a lot from each vent. Definitely feel safer knowing that my dryer will work properly and that nothing can catch fire. Thank you, Brian!"

"We were very pleased with the Richard and Ben's work.  They were extremely professional and responded to all our questions and gave us some additional advise which regard to the vents and potential solutions which we ultimately implemented solving our leakage issues.  I also visited the company's site and researched other references prior to hiring Trusted.  In every case nothing but high marks were given and after our service I can see why.  Trusted will be my go-to HVAC contractor from now on.  Extremely professional.

Heating and Air Conditioning questions, answered by experts

Yes, scorpions can enter a home through AC vents, especially if the system is not well-sealed. As excellent climbers, they can scale a home's exterior and squeeze through gaps as small as 1/16 of an inch. Scorpions are often attracted to the moisture around air conditioning ducts or seek cooler areas during hot weather, using vents as a pathway inside. They may slip through small openings where the duct meets the vent cover and travel within walls before emerging. To prevent this, inspect your vents, seal any gaps, and consider installing fine mesh screens.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air

Replacing an HVAC system does not always include new ductwork. The decision depends on the condition of your existing ducts. If they are in good shape, correctly sized for the new unit, and meet current standards, they can often be reused. However, if the ducts are damaged, poorly designed, or improperly sized, they will likely need to be replaced or upgraded to ensure the new system operates efficiently. An HVAC contractor will assess your ductwork and recommend the best course of action. Typically, ductwork is purchased separately, and a full replacement will add to the overall project cost.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.
