Middletown sits in the Middletown Valley in western Frederick County, between Catoctin Mountain and South Mountain. Homes here run from old farmhouses and village houses along Main Street to subdivisions built much more recently, so on any given week we might be bleeding radiators in one house and replacing a heat pump in the next. Cold winters and humid summers mean both halves of the system earn their keep. For plumbing service in town, see our Middletown, MD page.
HEATING
Furnaces, Heat Pumps and Boilers in the Middletown Valley
Heating is where most of our Middletown calls start. Gas and propane furnaces fail in familiar ways: an igniter that cracks, a flame sensor coated in residue, a pressure switch that will not close. Our furnace repair visits test each part in order rather than guessing. Heat pumps bring their own set of problems, from defrost boards to outdoor fan motors, and a heat pump repair call checks the refrigerant side and the electrical side together.
Boilers deserve their own mention. Many older homes in the valley still heat with hot water or steam radiators, and a boiler that is maintained can run quietly for a long time. Annual service covers the burner, the circulator pump, the expansion tank, the relief valve and the venting. If a boiler has reached the end of its life, we can talk through boiler installation options that keep the radiators you already have.

Fantastic service - bought a home with a very old hot water heater, and Brick Street’s quote came out to be substantially less than the other plumbers I spoke with. No compromise on service for the price, though - Mary was incredibly responsive and friendly when it came to scheduling a time to install the new water heater, and Tylerr did an outstanding job getting the water heater set up and running. Overall very easy to work with, reasonably priced, and professional!
Alex Lafrance⭐⭐⭐⭐⭐ Excellent Service – Highly Recommend Brick Street Plumbing Water Heaters I recently had my entire HVAC system replaced after my old unit had been in my home for over 20 years. I requested an estimate through Home Depot, and they referred me to Brick Street Plumbing. Water Heaters, From beginning to end, my experience was excellent! Brian came to my home, carefully explained the different options available, and walked me through the entire installation process. He was very professional, knowledgeable, patient, and always available to answer my questions. Communication with Brian was outstanding throughout the entire project. One of the best parts of the installation was that they were able to relocate my water heater into an unused space in my basement. This made the entire HVAC area much more spacious, organized, and accessible. I am extremely happy with how everything turned out! I also want to recognize Austin, Gmo, and Dani for their excellent work. They were professional, hardworking, respectful of my home, and paid great attention to detail. The entire team did an amazing job! Replacing an HVAC system is a major investment, but Brick Street made the entire experience smooth and stress-free. I am extremely satisfied with the quality of their work, professionalism, and customer service. I highly recommend Brick Street to anyone looking for a reliable company for HVAC installation or replacement.

Aman SethiUpdate 10/2/2026 The manager got in touch with us and promptly sent out a service technician that was able to quickly diagnose and troubleshoot the issue with our thermostat. ------------------------------------------------------------------------------------------------------ We got our AC replaced by Brick Street through Home Depot. After a week our AC wasn't working so we had to put in a service call. They came out and fixed it. Then our heating wasn't working and we put in a service call to have a tech come out to and troubleshoot but their HVAC department has been non responsive via email or voice mail. We are not able to get in contact with them at all. Will not be doing business with this company again. Very poor customer service.
Hai NguyenGreat service and installation by Tyler!
Adrian CalameVery very pleasant and professional and explained everything...

When an Upgrade Beats Another Repair
There comes a point where nursing an old system along costs more than it saves. Repeated repairs in a short span, rising energy bills with no change in habits, uneven temperatures and an outdated refrigerant are all signs to weigh replacement. A modern furnace, heat pump or air conditioner sized correctly for the home runs more quietly and uses less energy than the unit it replaces.
We plan an upgrade carefully: measuring the house, checking the ductwork and electrical service, and confirming the venting suits the new equipment. You get a clear picture of each option before anything is ordered. Everything we install is listed on our HVAC services page.

Frequently asked questions
Can a Middletown, MD house with radiators get air conditioning?
Yes. The most common route is a ductless mini split system, which uses small refrigerant lines instead of ducts and mounts slim indoor units on walls or ceilings. It leaves the boiler and radiators in place for heat. Another option is a high-velocity system with small flexible ducts that fit inside walls and closets. We look at the layout of the house and suggest which approach disturbs it least.
How long does a furnace last in a Frederick County home?
A well-maintained furnace often lasts well over a decade, and some run much longer, but the real answer depends on how it was installed and cared for. Furnaces that were oversized short-cycle and wear out sooner, and units that go years without cleaning or filter changes suffer too. Instead of judging by age alone, watch for rising repair frequency, uneven heat, rust or soot, and higher energy bills.
Should a boiler be serviced every year?
Yes, an annual check is a good habit for any boiler. The technician inspects and cleans the burner, checks combustion and venting, tests the relief valve and low-water cutoff where present, and looks at the circulator pump and expansion tank. Early fall is the ideal time, before the heating season begins. Regular service helps a boiler run efficiently and catches small leaks or worn parts before they cause a no-heat call.
What size air conditioner does my Middletown home need?
The right size comes from the house itself, not from square footage alone. Insulation, window area and direction, ceiling height, air leakage and the number of people living there all change the cooling load. An oversized unit cools fast but leaves the air damp, while an undersized one runs constantly. We measure and calculate before recommending a size, and we check whether your ducts can carry the airflow it needs.
Do you provide HVAC service for businesses in Middletown?
Yes. We work on heating and cooling equipment in shops, offices and other small commercial spaces as well as homes. That includes split systems, rooftop units, ductless setups and boilers. Because we answer 24/7 with no overtime fees, a business with a failed system after hours can call right away instead of waiting for the next business day to start the clock.
