Yes, absolutely. Just like a car needs oil changes and tire rotations to run reliably, your home’s HVAC (heating and cooling) system requires regular maintenance by a qualified technician.
Scheduled maintenance and tune-ups are essential for optimal performance, energy efficiency, and preventing unexpected, costly breakdowns.
Twice a year, usually during the Spring and Fall. Similar to a your vehicles oil change, regular maintenance on your home HVAC system keeps it running efficiently saving you money year round and it helps prevent costly emergency breakdowns. Our maintenance plans will keep you comfortable all year round.
Our seasonal maintenance ensures your comfort and safety year-round. We tune up your cooling in spring and your heating in winter, with every visit including a full safety and efficiency inspection.
A thorough tune-up should include the following:
You should change your home air filter every 1-3 months for standard 1-inch pleated filters, but check it monthly, especially with pets, allergies, or heavy HVAC use.
Thicker filters (3-5 inches) that are usually located in a media cabinet near your air handler or furnace can last longer, up to 6 months.
If you’re unsure, always refer to your unit’s operating manual for any specific manufacturers recommendations.
While homeowners can (and should) perform simple tasks like changing air filters regularly, and inspecting or lightly cleaning their outdoor unit for dirt and debris build-up, a professional inspection and maintenance is essential.
Certified technicians have the tools and expertise to diagnose hidden issues, handle refrigerants safely, and perform calibrations that directly impact efficiency and longevity tasks that go beyond DIY.
If your AC fan runs but no cold air comes out, the most common causes are a dirty air filter (causing the coil to freeze), low refrigerant (from a leak), or a failed capacitor or compressor in the outdoor unit.
First, replace the air filter and ensure vents are open, this ensures the unit has adequate air flow.
If that doesn’t help, turn the system off and call us, our technicians perform a full system diagnosis to pinpoint the exact issue and provide a clear, upfront solution.
A water leak typically indicates a clogged condensate drain line. This line removes humidity collected from your air and can become blocked with algae or mold. Other causes include a broken condensate pump or a frozen evaporator coil. Turn off the system to prevent water damage and contact a technician to clear the line and inspect the unit.
With proper annual maintenance, a well-installed central AC unit typically lasts 15 to 20 years. Lack of maintenance, constant use in extreme climates, or improper sizing can shorten its lifespan to 10-12 years. If your system is over 15 years old and requires frequent repairs, it may be more cost-effective to consider a replacement.
An AC unit freezes due to restricted airflow (from a dirty filter or blocked vents) or low refrigerant levels. Both issues prevent the evaporator coil from absorbing heat properly, causing condensation to freeze. Turn the system off to let the ice melt and call Oklahoma Heat, Air, and Refrigeration to schedule a technician to address the underlying issue before restarting.
The right size air conditioner isn’t just about cooling power it’s about precision comfort, efficiency, and system health. Using outdated “square footage per ton” rules often leads to two costly mistakes:
The Oversized System: Cools the temperature but not the humidity (leaving air sticky), turns on and off constantly (wasting energy and wearing parts), and creates uncomfortable hot/cold spots.
The Undersized System: Runs non-stop on the hottest days (skyrocketing bills), never achieves the set temperature, and burns out prematurely from overwork.
To avoid these issues, our technicians perform a comprehensive Heat Load Calculation. This computer-based analysis goes far beyond square footage to account for your home’s unique blueprint, insulation, windows, sun exposure, and even daily household activity. The result is a perfectly sized system that:
Maintains consistent temperature and ideal humidity.
Operates quietly with fewer on/off cycles.
Minimizes energy consumption and extends equipment life.

Yes, absolutely. A severely clogged filter restricts airflow over the evaporator coil, causing it to freeze into a solid block of ice. This ice buildup blocks all airflow and can trip safety sensors, shutting the system down entirely. Simply replacing your air filter every 1–3 months (for 1″ filters) is the easiest and most important maintenance step you can take to prevent unnecessary breakdowns and maintain cooling efficiency.
A furnace blowing cold air often indicates a delayed ignition due to a dirty flame sensor, a faulty hot surface ignitor, or a problem with the gas valve or supply. For electric heat pumps, it could mean the system is in defrost mode or you may need to turn on emergency heat mode. Check your thermostat settings first, then contact a heating repair technician for a diagnosis. We’ll be more than happy to get you home warm and comfortable again, give us a call!
First check that your thermostat is set to “HEAT” and is below room temperature, ensure the furnace power switch is on, and check your home’s circuit breaker.
If these are fine, the issue could be a tripped limit switch, a failed inducer motor, or a malfunctioning thermostat.
For safety, further diagnosis should be done by a licensed technician.
The average lifespan of a well-maintained gas or electric furnace is 15 to 20 years. If your furnace is over 15 years old and needs frequent repairs, upgrading to a new, efficient model is often more cost-effective. We offer free estimates for all replacements and upgrades.
The limit switch is a critical safety device that shuts off the burner if the furnace overheats, often due to restricted airflow (dirty filter, closed vents, failing blower). If it trips repeatedly call our office to schedule a technician to diagnose and resolve the root cause to prevent a hazardous condition.
This indicates the system is struggling to meet the set temperature. Common causes include a dirty air filter, leaky ductwork, an undersized furnace, or a failing component like the heat exchanger or gas valve. This strains the system and increases bills schedule a diagnostic service visit as soon as possible to prevent a costly breakdown!
Absolutely. A clogged filter restricts airflow, causing the furnace to overheat. This triggers the safety limit switch to shut the system down to prevent damage. Regularly replacing your filter is the simplest and most important thing you can do to prevent unnecessary breakdowns.
