Holtzople is a leading HVAC company in Frederick, Carroll, and Washington counties in Maryland, as well as Adams and small parts of Franklin & York counties in Pennsylvania, featuring all the top brands in the Heating and Cooling industry, such as Trane, Bryant, Lennox, Carrier, ClimateMaster, WaterFurnace, and more. We recently added an electrical department to our services, making us your one-stop shop for HVAC and electrical needs. Quality is Not Expensive, It's Priceless!

"Happy Holidays all! Please use my Holtzople (H) review to help you address your HVAC needs! Last summer, my Trane AC unit failed. Corey W (H) was the tech that came out to the house and troubleshooted/resolved the problem (leaking refrigerant). He also advised on probability of future repairs. Sadly, the unit performed well for only a short time before failing. It was time to consider my options. Repairs were becoming more frequent and costly. Tyler (H System Designer) visited and walked around my house inspecting my current HVAC system. We discussed repairing or replacing my ailing AC unit. He recommended replacing with a split ductless system and emailed a quote for 1. Enhanced Mitsubishi hyper heat mini split system (system) 2. Favorable financing options - low interest rates and affordable monthly payments. The install took a week. H’s crew arrived each morning, respected my property, and worked as a team to carefully install the new system. With gratitude, John"

"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."

Our commitment is 100% guaranteed customer satisfaction on every project. Call us today, so that we can give you a free estimate and make your project come to life!

"Josh, the representative from Basement Gurus was outstanding! We had experienced a water issue in our finished basement. Josh thoroughly examined the interior and exterior of the home and determined that the leak might be plumbing related. Josh could have very easily exploited our ignorance and suggested a solution purely beneficial to his company that may not have addressed the underlying cause of the problem. Instead, he demonstrated his integrity by realistically assessing the situation even if it would jeopardize the sale. This is commendable particularly in this era where cutthroat business practices are commonplace. I highly recommend Basement Gurus. They are fortunate to have an employee like Josh who exhibits concern for the customer at such a high level. "

Subcontractors questions, answered by experts

It pays to hire a project manager or general contractor when you have a large-scale project that will take over a week to complete, especially when it involves structural changes and multiple subcontractors. This includes hiring a general contractor to build a house, add an extension, or manage other projects that need a building permit.

Yes, most general contractors require a down payment for project completion. A reasonable down payment for a contractor is 10% to 25% of the total project cost, though that will vary based on project size and location. The down payment helps cover the upfront costs of materials and permits and helps ensure payment for the project at hand. 

Construction typically takes 1-3 weeks, depending on the project’s scope and customization.

No, builders and general contractors don’t expect tips. In fact, some companies may prohibit their employees from accepting client tips. If you want to show gratitude for a job well done, consider writing a review of your builder or contractor or agreeing to be a reference for potential new customers.

General contractors typically manage home renovation or build projects that last more than a week and involve various skilled tradespeople. Some examples include building a new home or barn, adding an extension or garage, or carrying out major room remodels involving extensive plumbing, electrical, and structural changes.
