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

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."

"Came home to my washer leaking after a long week. Small river in my condo.

FAQs for central humidifier installation and replacement projects in Hancock, MD

Unless you have advanced HVAC, plumbing, and electrical skills, hiring a pro is worth the investment. Improper installation can strain or even damage the furnace, leading to repairs that dwarf the cost of professional labor. Certified installers deliver a precise, code-compliant setup and help the system run efficiently for years.

Your whole-house humidifier choice comes down to budget and upkeep. Drum models cost less but demand frequent pad changes and vigilant cleaning to avoid mold. Flow-through units carry a higher price tag yet need less maintenance because water drains away rather than sitting in a reservoir. Decide how much ongoing work you’re comfortable handling before you buy.

Whole-house humidifier repairs average $230 but can reach $500, based on unit type, repair complexity, and local labor rates. Systems tied into extensive ductwork or large homes tend to cost more to fix. Routine maintenance, like the occasional pad change, cleaning, and inspection, helps you avoid those higher repair bills and keeps the humidifier working longer.

If indoor humidity regularly falls below 30%, a whole-house humidifier is a smart upgrade. Dry air aggravates allergies, chapped skin, and static, while ENERGY STAR recommends 30% to 50% year-round (30% to 40% in cold climates to curb condensation). If levels climb above that range, consider a whole-house dehumidifier instead.

A well-maintained whole-house humidifier lasts for 10 to 15 years. If yours is pushing a decade and performance drops or energy use climbs, start planning for a replacement. Upgrading boosts efficiency and indoor comfort, and an HVAC pro can confirm whether repairs or a new unit make better financial sense.

A whole-house humidifier is installed directly into your HVAC system and positioned near the furnace or air handler to maximize performance. It connects securely to both the ductwork and plumbing systems, ensuring complete integration. Hiring a professional guarantees a safe, efficient, and permanent installation that protects your system from future operational issues.
