Expert Solutions for Waltham Homes

From scheduled maintenance to major infrastructure overhauls, executed to the highest trade standards.

01

Furnace & Boiler Repair

Fast, accurate diagnosis and repair for gas furnaces, oil-fired furnaces, hot water boilers, and steam boilers — from failed igniters and blower motors to leaking radiators and no-heat emergencies. As Waltham's local heating oil supplier and furnace repair service, we stock the parts most older New England systems need, so most repairs are done in a single visit.

  • ✓ Code-compliant installation
  • ✓ Upfront agreed pricing
  • ✓ Workmanship warranty included
02

Steam Boiler Tune-Ups & Maintenance

Annual precision tune-ups for steam and hydronic systems, including burner combustion adjustment, low-water cutoff testing, gauge glass cleaning, and air vent service — the maintenance that keeps century-old radiator systems in Waltham's older homes running quietly and efficiently. A properly tuned oil boiler burns cleaner, uses less fuel, and is far less likely to quit on the coldest night of the year.

  • ✓ Code-compliant installation
  • ✓ Upfront agreed pricing
  • ✓ Workmanship warranty included
03

Ductless Mini-Split & Heat Pump Installation

High-efficiency ductless mini-split and central heat pump design and installation, perfect for adding quiet, zoned cooling and heating to a single room or a whole house without tearing open walls. We handle cold-climate heat pump sizing, line-set routing, electrical coordination, and full oil-to-heat-pump conversion — many of our Newton and Lexington customers cut heating costs dramatically while gaining air conditioning they never had.

  • ✓ Code-compliant installation
  • ✓ Upfront agreed pricing
  • ✓ Workmanship warranty included

“Very happy with Genove's work. Armando discussed the project with us on the front end, thoroughly considering and educating us on the various options. In the end, we opted to install a ductless AC in one room. The price seemed very fair. The work by Richie and Ryan was carried out as scheduled, efficiently, and well. All were professional, friendly, and helpful. I'd recommend them to anyone.”
