"Great job. Anthony did a complete review of the house and the current venting and recommended the proper size for the AC. The installers and electricians came 3 days later, did additional wiring and piping and installed the entire system in 5 hours."

Hydro jet uses water at 4,000psi to clean the inside of the mainline drain which connects all the home's drains to the city's sewer system.
Using a snake we can go through the cleanouts on the side of the house.
With the cleanouts snaked, and the blockage located, we can send the hydro jet through the sewer vent and flush out the blocked drain.

"Javier (initial POC) and JR (the onsite technician) were GREAT! Javier called several times to make sure I understood everything that JR would be doing. When JR arrived, he was very courteous and professional. He explained the steps he would go through to troubleshoot my AC. he quickly found the problem (bad capacitor), and replaced it quickly. The whole process was less than an hour. Highly recommend Javier and his team for any heating and air conditioning issues that may arise (including purchase and installation)."

"I had a great experience from start to finish with Attic Shield. Elliott called to check in and see how you were doing after the service. My family and I noticed a huge difference with the air conditioning holding the indoor temp cooler especially during these warmer summer days. Thanks again Elliott."

"The team installed new chimney caps due to deteriorating conditions that needed repair. They took the time to explain step by step what this repair involved. The team showed up on time, completed the job in the estimated time frame, and left absolutely no mess to clean up. It was a pleasure dealing with this company."

"I replaced an "In wall" Air conditioner & Heater. This vendor found ne an exact fit for the existing hole and the 110 Volt operating system, not the 220V used by most companies. The price to replace and haul the old unit away, was very low and I was particularly impressed with the friendliness of Edgar, the owner! This transaction was based on mutual trust, of performance, and I was not disappointed."

Customers say: True professional

"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"

Air Conditioning questions, answered by experts

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

High humidity is one of the most common reasons for air vents to sweat or produce condensation. When the cool, dry air from your HVAC unit meets warm and moist air in your home, it will cause condensation. Insulating your ductwork can help prevent this. If you live in a very humid region, a dehumidifier can also help.

Here’s how AC professionals will clean your AC coils:

  1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

  2. Remove the faceplate.

  3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

  4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

  5. Use the vacuum hose to suck up any extra debris.

  6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

  7. Let the solution sit for at least 15 minutes.

  8. Gently wipe away loosened grime and debris with a microfiber cloth.

  9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.

Trick question: There is no difference between an AC and a furnace blower motor. Whether you have central air and heat or just one of these, the same blower motor carries hot and cold air throughout the ductwork in your home. Certain systems may have separate blower motors for the AC and furnace, but each serves the same function.

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.
