Frequently Asked Questions
Understanding your home's systems can be complex. We've gathered the most common inquiries about HVAC, electrical, and our unique service approach. Our goal is to provide you with clear, concise answers that build confidence in choosing A & H Electrical Heating & Cooling for your needs.
How effective are air cleaners at removing allergens?
Our high-efficiency air cleaners can remove up to 99.98% of airborne allergens, significantly improving air quality, especially for homes with allergy sufferers or pets.
What size furnace do I need?
Furnace size is based on square footage, insulation, ductwork, and airflow — not just the old unit size. Oversized equipment causes short cycling and uneven heat. We evaluate the home to recommend the correct capacity.
What size air conditioner do I need?
Air conditioners must be matched to the home and duct system. Bigger is not better. Incorrect sizing leads to humidity problems and higher energy bills.
How long does installation take?
Most residential equipment replacements take one day. More complex systems or commercial equipment may require additional time depending on electrical and duct modifications.
What are your hourly charges?
Service is based on diagnosis and repair scope. We explain findings and options before work continues so there are no surprises.
How often should I replace my air conditioner?
Typical lifespan is 12–18 years depending on maintenance and operating conditions. We only recommend replacement when repair is no longer reliable or cost-effective.
Can a heat pump lower my energy bills?
In many homes, yes. Heat pumps can provide efficient heating and cooling, especially during mild temperatures. We determine if your electrical system and home layout are suitable.
Do I need a humidifier in my home?
It adds controlled moisture to the air while the heating system runs, maintaining a comfortable indoor humidity level.
Are programmable thermostats worth it?
Yes. Proper programming reduces run time and improves comfort. Smart thermostats also help monitor system operation.
How can i lower my electric bill with lighting?
Upgrading to LED lighting significantly reduces energy usage and heat output while improving reliability.
I think I have an electrical short — what should i do?
Turn off the affected circuit and avoid resetting repeatedly. Electrical faults should be diagnosed to prevent damage or fire risk.
Do you offer after-hours service?
Yes. Emergency and after-hours service is available for urgent situations affecting comfort, safety, or business operation.
Do you service restaurants and commercial buildings?
Yes. We regularly service restaurants, commercial facilities, and industrial equipment including ventilation and refrigeration systems.
How far do you travel?
We serve Metro Detroit and Southeast Michigan including surrounding communities.
Problems we fix that others often miss
Many system failures are not caused by the part that stopped working. They are caused by an electrical, airflow, or control condition that keeps damaging the equipment. Our combined electrical and mechanical approach allows us to identify the real source of the failure.
Repeated breaker trips
Often blamed on motors or compressors, but commonly caused by wiring issues, incorrect circuit sizing, or electrical load problems.
Furnace or AC replacing parts repeatedly
When capacitors, boards, or sensors keep failing, the system usually has voltage, grounding, or airflow conditions shortening component life.
Intermittent operation
Systems that work sometimes and fail other times are typically control or electrical signal problems, not equipment failure.
New equipment not working properly
Improper wiring, airflow setup, venting, or control configuration can prevent new systems from operating correctly. We evaluate installation conditions, not just the unit.
Units locking out or needing constant reset
Safety devices activate for a reason — overheating, combustion issues, electrical signal loss, or airflow restriction. We find and correct the condition causing shutdown.
High energy bills
Oversized equipment, improper setup, or electrical inefficiencies cause excessive run time. Correct system operation restores efficiency.
Restaurant equipment failing during operation
Ventilation balance, electrical supply, and refrigeration load must work together. We diagnose the system as a whole to prevent downtime. Our goal is not temporary operation — it is reliable operation.
What makes A&H different?
Most companies specialize in only one trade. HVAC companies replace parts. Electricians repair wiring. But modern equipment depends on both working together. A&H Electrical Heating & Cooling is built around understanding the entire system. Our background in electrical and mechanical service allows us to diagnose the root cause of failures instead of repeatedly replacing components. Many customers call us after multiple service visits elsewhere because the problem keeps returning. We focus on correct diagnosis, safe operation, and long-term reliability — not temporary fixes or unnecessary replacements. One contractor. One diagnosis. The problem fixed properly.
Our service process
We keep service straightforward and clear so customers know exactly what is happening at every step.
1. Schedule & Arrival: We arrange a service time and arrive prepared to diagnose the issue. For urgent problems, after-hours service is available.
2. Complete System Diagnosis: We evaluate electrical supply, controls, airflow, and mechanical operation — not just the failed part — to identify the real cause.
3. Explanation Before Repair: Findings are explained in plain language along with repair options. No work is performed without approval.
4. Proper Repair: Repairs are completed cleanly and safely with attention to long-term reliability, not temporary fixes.
5. Verification & Operation Check: The system is tested to confirm proper and safe operation before leaving.
Our goal is simple: fix the problem correctly and make sure you understand what was done and why.
