Reliable HVAC Repair and Preventative Maintenance
Serving Middle River & Surrounding Areas
Comprehensive HVAC Repair Services
Fast Diagnostics, Lasting Fixes
When your AC or furnace falters, D&J Solutions LLC delivers fast, precise diagnostics to stop discomfort and damage. Our seasoned technicians use digital gauges, thermography, and electrical testing to pinpoint failures—whether it’s low refrigerant, a stuck contactor, a failed igniter, or a clogged condensate drain. We address root causes like airflow restrictions, duct leakage, or control faults rather than masking symptoms, restoring performance safely and efficiently.
We service all major HVAC configurations: gas and electric furnaces, heat pumps, central AC, ductless mini-splits, and packaged units. Typical repairs include compressors, blower motors, capacitors, contactors, relays, control boards, thermostats, TXVs, evaporator and condenser coils, draft inducers, flame sensors, pressure switches, and drain systems. EPA 608–certified pros handle refrigerant leaks and charging correctly, and our stocked vehicles enable many same-day fixes.
Lower Bills, Longer Equipment Life
Preventative maintenance lowers utility costs, prevents surprise breakdowns, and extends equipment life. Our tune-ups follow a 20+ point checklist: deep coil cleaning, drain pan and line treatment, filter replacement, refrigerant charge verification, amp-draw and voltage testing, tightening and lubrication, thermostat calibration, static pressure and airflow measurements, and safety control checks. For combustion equipment, we include combustion analysis, gas pressure adjustment, and flue draft verification.
The payoff is measurable: improved efficiency, quieter operation, better humidity control, and cleaner indoor air. Many manufacturers require annual service to keep warranties intact. Ask about our maintenance plans, which include seasonal visits, priority scheduling, repair discounts, and reminders—so your system stays optimized year-round without the hassle.
Transparent Process From Start To Finish
Expect a smooth, transparent experience. We offer convenient scheduling, clear arrival windows, and a call or text when we’re on the way. On site, technicians protect floors, verify the issue, and present options with upfront, no-surprise pricing. We proceed only with your approval and explain what was done, what to watch, and how to prevent future problems.
Quality is backed by training and accountability. Our licensed, insured, and background-checked team includes NATE-certified technicians experienced with Trane, Carrier, Lennox, Goodman, Rheem, York, Daikin, Bosch, and more. We follow best practices—nitrogen-purged brazing, proper evacuation, micron verification, accurate airflow setup, and code-compliant electrical and gas work.
Your investment is protected by workmanship guarantees and manufacturer-backed parts warranties. We document every visit, provide digital reports with photos as requested, and keep your system history to speed future service. If something isn’t right, we make it right—promptly and professionally.
