## The honest read

Muller Heating & Plumbing works on heating systems and plumbing, and the company says it has been in business 24 years. Its BBB profile lists boiler installation and cleaning, burner service, forced hot air and hot water, radiant heating and steam boilers among its services, and BBB grades it A+.

A 2025 customer said they had used the company for seven years, that the service technicians were efficient, willing to answer questions and arrived in a timely manner, and that the office called to say when they were on the way. That customer said they relied on the company for furnace maintenance and all their plumbing needs.

A 2026 customer who had used the company for eight years said they called about a leak in a bathroom faucet. That customer said the tech looked at it, did no work, said a lot of drywall would need to be opened up, and still charged for an hour; a different plumber then had the job done in 30 minutes.

A 2025 customer said they called for service and were told the company didn't take on new customers. A 2025 customer said the owner spoke to them in a condescending manner on the phone, said they had big jobs underway, and couldn't say when someone would be out.

**Strengths:**
- Furnace maintenance — a 2025 customer relied on them over seven years
- Office arrival call — a 2025 customer said the office called before arrival

**Concerns:**
- Charged without a repair — a 2026 customer paid an hour for a faucet visit
- New customers turned away — a 2025 customer was told no new customers
- Phone manner — a 2025 customer said the owner was condescending
