Signs Your HVAC System Needs Maintenance

Taking care of your HVAC system ensures it operates efficiently and can help avoid unexpected breakdowns. Here are some common signs that it’s time for professional maintenance:

  • Inconsistent temperatures: If some rooms are too hot or too cold, your system may need attention.
  • Strange noises: Banging, squealing, or rattling sounds can signal mechanical issues.
  • Higher energy bills: If your utility costs are rising but your usage hasn’t changed, your system might be working harder than it should.
  • Frequent cycling: If your system is turning on and off too often, it could be struggling to maintain the set temperature.
  • Unpleasant odors: Musty or burning smells may indicate issues that require immediate attention.

Scheduling regular maintenance can help address these problems early and extend the life of your system.

Mr. Mossor always informed me of what he was doing each day he came to my house to replace my upstairs furnace and AC unit. Was on time everyday and took great care while working in my home. I could not have contracted with a better person.

Carl was able to get to our house on short notice on a weeknight when we sprang a radiator leak just before Thanksgiving with a houseful if guests on the way! Looked like a disaster looming but he got the problem stopped quickly and gave us an accurate estimate of the time it would take to get the radiator replaced. He always showed up on the date and time he promised. He was very clear in his communications via text messaging. All in all he did a first- class job! Will definitely call on him again in the future for our furnace & radiator care.

Carl was quick to respond to our request, he offered a fair comparable price to other companies and he was able to point out some installation issues for a new unit that other service techs had not noticed prior to beginning installation.
Graham - Stephens City, VA 22655
Review
Carl is extremely professional, knowledgeable, courteous, organized, prompt, great communication, easy to work with, and was able to resolve any issues I had as well as answer any questions I had. I had many quotes but chose to go with Carl and his company to perform my HVAC work and highly recommend him and will definitely go to him with any other HVAC questions, concerns, or other work.
