"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

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.

When first installed, flex ducts shouldn’t cause airflow problems in your home. However, because flex ducts aren’t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren’t tight enough, your HVAC could work twice as hard for the same air pressure. If you’re worried about the airflow in your home, a rigid duct may be your best bet.

Yes, mini-split systems are generally less expensive to run than central air conditioners and are significantly more energy-efficient. Because mini-splits do not rely on ductwork, they avoid the energy loss associated with ducted systems, allowing cooled or heated air to reach its destination more efficiently. Additionally, they offer zoned control, meaning you can run units in individual rooms and turn them off in unoccupied areas. This capability can lead to energy savings of about 30% compared to a central air system, resulting in a lower monthly energy bill.

Don’t run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs. Fix the problem (with a pro’s help, if you need it), and put a dry filter in place before you turn the system back on.

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.
