We were a little apprehensive when ER Services acquired Jones Heating & Air since Jones had taken care of us for many years, and ER Services is located a fair distance from our home. However, they have exceeded our expectations. They have consistently been dependable, professional, stand firmly behind their work,…
Kevin was very helpful and informative. He talked me through each step. I would recommend him to everyone.

ER Services has helped us w our HVAC Gaspack/s for over 25 years. They do excellent work, communicate well, & always keep us informed. They are installing a new HVAC system today. They brought us 2 room AC units for our den/kitchen & our bedroom. I highly recommend them.
The young man that came to my home, was top notch. He went above and beyond and I know he was hot. I appreciate him for all his hard work and doing his best. Thanks so much we need more people like you who will do all they can and be honest. I will always be grateful for the good people that I come into contact with. Thanks
ER Mech / Plumbing always does a fantastic job! We hired them to do repairs in our neighborhood and I have hired them for both mechanical and plumbing and they're very professional. I believe they can be trusted not to overcharge and they know their stuff. I recommend Dashawn for HVAC service for sure!
Dashawn Spellman was thorough, patient, and helpful with information I asked for. Knowledgeable and trustworthy. Great person.
Kevin is very professional, knowledgeable and answered all of our questions and concerns. Would love to have Kevin as our regular technician!
Kevin performed the 2026 spring maintenance cycle on my York HMH7 inverter heat pump system. Kevin did a very good job which included a static pressure test which is something that I have been wanting for sometime now. He was very accommodating to my many questions and is very knowledgeable with these systems.
