FAQs
What are the most common signs that my heating system needs professional repair?
Watch for uneven temperatures in different rooms, unexplained rises in utility bills, short-cycling (the furnace turning on and off quickly), unusual noises such as banging or squealing, persistent odors, or a yellow instead of blue burner flame. If you notice any of these in your Blaine home, call Precise Diagnostics Heating & Air Conditioning right away—ignoring them can lead to costlier damage or safety hazards like carbon monoxide leaks.
How fast can Precise Diagnostics Heating & Air Conditioning get to my Blaine home in an emergency?
We offer 24/7 emergency service throughout Blaine and surrounding neighborhoods. Most winter call-outs are handled within two hours, even during peak cold snaps. Our technicians arrive in fully stocked vehicles, so in more than 90 % of cases we can diagnose and repair your heating system in a single visit.
Do you work on all brands and types of furnaces, boilers, and heat pumps?
Yes. Our NATE-certified technicians are factory-trained to service and repair every major brand—Carrier, Lennox, Trane, Goodman, Rheem, Bryant, and more—as well as gas, electric, and oil furnaces, hydronic boilers, and ducted or ductless heat pumps. We keep a large parts inventory on hand specifically for the models most commonly installed in Blaine homes.
What is included in a diagnostic service call, and how much does it cost?
A standard diagnostic visit includes a 21-point inspection: thermostat calibration, voltage and amp draw checks, airflow testing, combustion analysis, safety-switch verification, and visual inspection of the heat exchanger and flue. We then provide a written report with repair options and upfront pricing. The diagnostic fee is $99, which is waived if you authorize the repair during the same visit.
Can timely heat repair really lower my energy bills?
Absolutely. A malfunctioning blower motor, clogged filter, or cracked heat exchanger forces the system to work harder and consume more gas or electricity. Restoring proper airflow, combustion, and efficiency settings can reduce heating costs by 10–25 %, according to ENERGY STAR data. Many Blaine customers see the repair pay for itself within one heating season.
Is there anything I should check before calling for service?
Yes—confirm the thermostat is set to "Heat" and batteries are fresh, ensure the furnace switch and circuit breaker are on, and replace a dirty air filter. If you have a gas system, verify the gas valve is open. If those steps don’t restore heat, shut the system off and call us. Continuing to run a failing heater can damage components or compromise safety.
