Know the Warning Signs

Is Your Air Conditioner Trying to
Tell You Something?

These are common signs your air conditioning system may need professional service.

01

Warm Air from Vents

If your AC is running but blowing warm or slightly cool air, it may have refrigerant, compressor, or airflow issues.

02

High Energy Bills

An inefficient air conditioner works harder to cool your home, leading to higher monthly utility costs.

03

Strange Noises

Grinding, banging, rattling, or squealing sounds usually signal worn or damaged components that require repair.

04

Weak Airflow

Poor airflow often indicates clogged filters, duct issues, or a failing blower motor that needs attention.

05

Frequent Cycling

If your AC constantly turns on and off, it could be caused by thermostat issues, electrical problems, or an improperly functioning system.

Uneven Comfort Throughout the Home

When some rooms stay warm while others are cool, your air conditioning system or ductwork may not be distributing air properly.

Stratz designed and installed our original heating & AC system in our new house 17 years ago. It is a high-efficiency 3-zone system, and we have been extremely pleased with it. In addition, we have used Stratz every year for our annual inspections and check-ups, as well as the occasional repair and replacement. All of Stratz's technicians are very knowledgeable and experienced, and have always been very friendly and courteous. I wholeheartedly recommend Stratz without any reservations to anyone looking for a high quality professional heating and AC service.

Caleb was my technician. He replaced my blower on my furnance. He was kind enough to come back and explain the blower furnance noise after installation.

Not knowing other prices, i have nohing to compare the expense to.

I surely appreciated them, for it was a very cold night.

We had a leak in our on demand water heater at our cottage. We found it on our arrival after being gone for several weeks. Called them, Nick came within a half hour. Got it evaluated, turned hot water off and put a plan for replacement - this was a Friday afternoon. Got a call on Monday with our options, Tuesday afternoon Chad and his assistants were there. The install was great. Very professional, left everything clean and neat, answered all my husbands questions. Awesome job to all of you. Highly recommend!

We were very pleased with the responsiveness and quality of the work of the team at Stratz.
Reece was available to help with a furnace that decided to misbehave over the Christmas holidays. He let us know in advance of his arrival, diagnosed and fixed the problem quickly, and was courteous and professional throughout.
We had a similar good experience with Jacob in November on another problem. He was also thoroughly professional, courteous and helpful.
Highly recommend both technicians and the team at Stratz.

Caleb was awesome. He came the same day I called and although he had already put in a full day he stayed as long as it took. Not only did he fix a problem that has been ongoing for several years he was attentive, professional and very personable. My exceptionally shy grandson took to him; repeatedly watching and talking to him, not usually done with ANY stranger. Caleb is special. I know who to call now and will look into maintenance plans. Thanks for all you do.
How do I know if my air conditioner needs repair?

Common warning signs include warm air coming from vents, weak airflow, unusual noises, frequent cycling, water leaks, unpleasant odors, or rising energy bills.

Warm air can result from low refrigerant levels, dirty air filters, frozen evaporator coils, thermostat issues, or compressor problems. A professional inspection can identify the exact cause.

We recommend scheduling professional AC maintenance once a year, ideally in the spring, to improve efficiency, reduce breakdowns, and extend system lifespan.

Most common AC repairs can be completed during a single service visit, depending on the issue and parts availability.

If your system is over 10–15 years old, requires frequent repairs, or has significantly reduced efficiency, replacement may be the better long-term investment. Our technicians will always provide honest recommendations without pressure.
