What HVAC customers say
Roman did a great job servicing the AC units at both of our properties. He was professional, honest, and very thorough. He checked everything, explained what he found, completed the maintenance, and gave us useful recommendations. Fair pricing, great service, and easy to work with.

What this symptom usually means
a system that runs far more than it used to, without a change in habits or weather, is usually working harder than it should to reach the same result — a sign of an efficiency-robbing fault. It's rarely a single guaranteed cause, which is why a proper diagnosis matters.
Likely causes
- A dirty air filter or coil. Restricted airflow forces the system to run longer to move the same amount of conditioned air.
- Low refrigerant charge. A system low on refrigerant works harder and longer to reach the set temperature.
- Duct leaks. Conditioned air lost to unconditioned spaces means the system has to make up the difference.
- An aging or failing component. A weakening capacitor, motor, or compressor draws more power and runs longer than a healthy one.
- Deferred maintenance. Systems that haven't been serviced in a year or more often show up as a gradual bill increase before an outright failure.
Safe checks you can do first
These are safe for anyone — no tools, gas, refrigerant, or electrical work:
- Swap in a fresh air filter if it's overdue.
- Compare this month's runtime to the same month last year, if you can.
- Note whether any rooms feel noticeably worse than others, which can point to duct issues.
What not to attempt
- Don't assume it's just 'an old system' without a diagnosis — many efficiency losses are repairable.
- Don't delay — a system working this hard is often close to a bigger failure.
Repair first
Roxly focuses on repair and maintenance of existing residential systems. Most of the causes above are serviceable components — a capacitor, contactor, motor, or coil repair — which is why a proper diagnosis comes before any bigger conversation.
When to call a technician
A seasonal maintenance visit checks exactly the components most likely to be driving up runtime, before they cause a full breakdown. A technician diagnoses the actual fault and reviews findings and an estimate before any work. Service availability may vary by location, equipment type, brand, technician availability, and the scope of the requested work. Listing a city or service on this site does not guarantee same-day arrival. Contact Roxly Appliance & Refrigeration Repair to confirm availability for your address and equipment.
