McCrea is a family owned business that has served our area since 1936. Financing and rebates are available on Trane systems installed by McCrea. Resistrictions apply and these are limited time offers call for details. "Its hard to stop a Trane"

"We bought a new construction and McCrea installed the HVAC. Home inspection identified the heat pump was not working in Oct. 2020. McCrea identified it was due to leaking refrigerants and promise fixed the issue. Our electric bill was extremely high the following two months and the heat pump was not cooling in Spring 2021. McCrea sent technician and again repaired the system. Bought their maintenance plan. We had 4+ repairs plus regular tune up in the past two years. Last week the heat pump stopped cooling again. We are out of labor warranty and charge us with $89 diagnostic cost after membership discount. It took three days for them to send someone to check while we suffering 90F in our house. They identified the compressor dead and need replacement. They charge $1900 for labor after membership discount. Most likely cause of the compressor failure is "suicide" with assistance. Low refrigerant at beginning and over change in later repairs likely contributed the short life."

We are a small family owned Heating, Ventilation, and Air Conditioning (HVAC) company located in Sharpsburg, MD. The business was started in 1989 under the name of RW Harrell's Pump Service Inc. when Diane Harrell and Ronnie Harrell purchased a well pump and water system business from a gentleman that was retiring. Ronnie had worked in the HVAC field from the time he had graduated from high school so it was natural to add HVAC to the services that this new company would offer. Ronnie and Diane built the company by word of mouth and continue to grow the company in this manner. Additional DBA - Harrell's Services. Additional fax - 928-492-8004

When you move, you’re packing up more than just “stuff.” You’re packing everything that makes your house a home. Across town, the state, or the country - we’ll help you get it there safely.

"JK uses a virtual estimate to provide a quote. That's a trick! It's common that the price they quote is a lot lower than what you WILL HAVE to pay to get your stuff. The process was easy, but can say the estimate we received to move across the country was $5,000 higher than 2 large PODs to start. In the end, they ended up adding almost $8,000...b/c they quoted the incorrect weight to start, as well as charging for a smaller truck that we never requested. The moving company that did the physical part, wasn't JK, and they were hard, polite, and great workers! I reached out and begged JK to help with the major increase (added 65% more to the total...and that was NOT budgeted in whatsoever! After numerous requests for ANY $ help, we were told simply "No." I worked with the physical moving company and they offered to help with some of the expenses...JK, Nope, Nadda, & basically told me TOO D*** BAD! DON'T USE THEM FOR ANY QUOTES!"

FAQs for ducts & vents installation and replacement projects in Williamsport, MD

Return air vents aren't required in every room, but proper placement is essential for system efficiency. According to industry standards, you'll need one return vent for every 100 to 150 square feet of living space. Ideally, each room would have its own return vent, especially larger rooms exceeding 100 square feet. 

Without adequate return airflow, your HVAC system works harder, energy costs increase, and comfort decreases. A professional assessment can determine the optimal number and placement of return vents for your specific home layout.

Signs that your home needs additional return air vents include rooms that feel consistently stuffy, noticeable temperature variations between rooms, doors that slam shut when the HVAC system operates, or unexpectedly high energy bills. Excessive dust accumulation around supply vents can also indicate inadequate return airflow. 

If you experience these issues, consulting with an HVAC professional can help determine if adding return vents would improve your system's performance.

Supply vents deliver conditioned air into your living spaces, while return air vents draw room air back to your HVAC system for reconditioning. Supply vents push treated air into rooms, while return vents pull air from rooms back toward your heating and cooling equipment. 

Both components are essential for proper air circulation and system balance. Without sufficient return capacity, your HVAC system may experience pressure imbalances that reduce efficiency and comfort.

You should inspect and clean your return air vents at least once annually, according to industry recommendations. However, homes with pets, allergy sufferers, or noticeable dust buildup may benefit from more frequent cleaning. 

Regular maintenance helps maintain good indoor air quality and ensures your HVAC system operates efficiently. Professional duct cleaning, which addresses the entire system beyond just the visible vents, is recommended every few years, depending on your home's specific conditions.
