Paul at Delta T, from the start was responsive and professional. He responded within minutes of my request, arrived within hours and solved the lack of A/C issues. He even gave a thorough assessment of the HVAC system and provided recommendations to keep it optimal. His service is also the best value.
Save yourself some time and choose "Delta T Freelance Heating and Air LLC" first. We highly recommend them and will be using them for All our Hvac needs

Paul was friendly, professional, and prompt. He came out and fixed my hvac which was giving me no air. He came and replaced the faulty part in no time at all. He was very knowledgeable and helpful. Definitely would use him again!

My A/C unit had gone out on a hot day in May. Paul quickly responded to my inquiry and then listened patiently to the concerns I vocalized over the phone. Upon his arrival, he was professional and prompt to evaluate the issue. He even took the time to explain the issue. I appreciate the patience and the results. Thank you for your service, Paul. May you continue to be successful! Dr. T

I needed a new HVAC system for my townhouse and I was totally overwhelmed with the process. Paul from Delta T was responsive and calming in his demeanor. His explanation of the issue and solutions was made from a place of concern and educating me on the options rather than just a sales tactic. On installation day, he and his team showed up on time and ready to work. They made the decision to move the outdoor unit to a better location that allows better use of my backyard. I have lived in this house for 20 years and just assumed that the location of the unit was non-negotiable. I am very impressed with Paul and his team and recommend them highly to anyone and everyone.

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
We offer AfterPay and the prices are fair and transparent. Thumbtack charges per referral and that cost is taken into consideration to allow us to still be relatively profitable. This charge is consistent with current market pricing.
What is your typical process for working with a new customer?
We call immediately to understand your needs.
Once we determine the best course of action to assist you, we schedule.
During the appointment window we can provide you with a Qoute and hopefully execute all repairs on that visit.
Installations require more planning then repairs.
What education and/or training do you have that relates to your work?
I am a license Mechanical Master HVAC Technician in Maryland and Virginia with several years of on the job training as well as formal academic training.
I also have a bachelors in business.
