Ready for the Hot Weather?
Prepare Your Air Conditioner Before the Heat Arrives
Your air conditioner may sit unused for months before temperatures begin to climb. A professional tune-up lets a trained technician inspect the equipment, test its operation, and identify concerns before the system works through the hottest days of summer. Mark Hill Heating & Air provides detailed AC maintenance throughout Tulsa, Broken Arrow, and the surrounding metro.
Cooling Maintenance for the System You Rely On
What’s Included in an AC Maintenance Tune-Up?
Mark Hill follows a detailed process designed to evaluate the operation, condition, and performance of your air-conditioning system.
We inspect accessible cooling equipment and mechanical components for wear, corrosion, damage, loose connections, drainage problems, and other conditions that may affect performance.
Early spring is often the best time to schedule AC maintenance because it lets you inspect the equipment before summer temperatures and appointment demand rise.
We Service a Variety of Cooling Systems
Cooling Systems We Maintain
Different cooling systems require different maintenance procedures. Mark Hill services central air conditioners, heat pumps, ductless systems, and other common residential cooling equipment from all major brands. Each visit is tailored to the system installed in your home.
01
Central Air Conditioners
Central air conditioners rely on properly matched indoor and outdoor components, adequate airflow, proper refrigerant levels, reliable electrical controls, and clear condensate drainage. Maintenance lets the technician assess these areas and confirm the system cools as expected.
02
Air Handlers
The air handler circulates conditioned air throughout the home and plays an important role in airflow and cooling performance. We inspect accessible blower components, electrical connections, filters, airflow, temperature performance, condensate drainage components, and applicable controls for conditions that could affect comfort or system operation.
03
Variable-Speed and Multi-Stage Systems
Variable-speed and multi-stage systems adjust their output to match changing comfort demands. Maintenance includes inspecting applicable controls, airflow, electrical components, coils, drainage, and performance across the system’s available operating stages.
04
Heat Pumps
Heat pumps provide both cooling and heating from the same system. Cooling-season maintenance may include checking coils, refrigerant performance, airflow, electrical components, condensate drainage, and the system’s ability to transfer heat effectively.

05
Packaged HVAC Systems
Packaged systems combine heating and cooling components within one outdoor cabinet. The maintenance process depends on the system’s configuration, but it may include inspecting coils, electrical parts, blower components, airflow, drainage, and overall cooling performance.
06
Ductless Mini-Split Systems
Ductless mini-splits require care for both the indoor air handlers and outdoor equipment. Maintenance can include cleaning accessible filters and coils, checking condensate drainage, inspecting electrical components, measuring system performance, and confirming that each zone cools properly.

What Tulsa Homeowners Are Saying About Mark Hill
Frequently Asked Questions About Tulsa AC Maintenance
Before you schedule.
How often should I schedule AC maintenance?
Most residential air-conditioning systems should be professionally maintained once a year. The equipment manufacturer or an existing service agreement may include additional maintenance requirements.
What time of year is best for AC maintenance?
Early spring is a convenient time to schedule AC maintenance because it allows the system to be inspected before hot weather and peak service demand arrive. You can still schedule maintenance later if the equipment has not been serviced recently.
What is included in an AC tune-up?
An AC tune-up includes applicable inspection, testing, cleaning, lubrication, and adjustment of accessible mechanical, electrical, airflow, thermostat, coil, refrigerant-performance, and condensate components.
Is AC maintenance the same as an AC inspection?
The terms are sometimes used interchangeably, but a complete maintenance visit generally includes both an inspection and routine service tasks such as cleaning, testing, tightening, lubrication, and applicable adjustments.
Will maintenance prevent every AC breakdown?
No. Maintenance cannot prevent every component failure or guarantee uninterrupted operation. It can help identify developing concerns and address routine service needs before the system reaches the most demanding part of the cooling season.
Can AC maintenance help lower my energy bills?
Maintenance can help correct certain conditions that reduce system efficiency, such as restricted airflow, dirty accessible components, loose electrical connections, or improper operation. Actual energy savings depend on the equipment, its condition, home efficiency, thermostat settings, usage, and weather.
Do you maintain AC systems installed by another company?
Yes. Mark Hill maintains and repairs all major residential air-conditioning brands, regardless of who originally installed the equipment.
Is an AC tune-up the same as an AC repair?
No. A tune-up focuses on preventive inspection and maintenance. If we find a failed component or another repair need, we will explain the issue and provide an estimate before completing additional work.
Does a new air conditioner need annual maintenance?
Yes. New equipment should be maintained regularly to monitor its operation, identify developing concerns, and satisfy applicable manufacturer warranty requirements.
What Maintenance Plans does Mark Hill offer?
Mark Hill currently offers ECO, PRO, and ELITE Maintenance Plan levels. Visit our Maintenance Plans page or contact our team to compare current features, pricing, and benefits.
